Foreshadow: Women

"Pithouse Life" Sign at Mesa Verde

“Pithouse Life” Sign at Mesa Verde

Chapter 10 of Crucible of Pueblos, by Richard Wilshusen and Elizabeth Perry, looks at the position and roles of women in early Pueblo society, with a particular focus on how those roles seem to have changed with the economic and demographic changes of the late Basketmaker III and early Pueblo I periods that recent research is bringing into focus. It’s a thought-provoking chapter but in some ways rather odd, with many of its most intriguing proposals resting on what seems like fairly thin evidence.

The chapter looks at three main topics: food production, human reproduction, and gender relations in social power. Its overall thesis is that in the northern Southwest between AD 650 and 850 interrelated changes in food production systems and human reproductive rates led to major changes in gender roles, particularly regarding the division of labor between men and women, that may have led to settlement aggregation into villages and to changes in social power related to trade and ritual. The resulting social structure, in place by the end of the Pueblo I period in at least some areas, was the earliest form of the “Pueblo” society as known from modern ethnography, with its strict division of labor by gender and extension of this gendered ideology to many other domains of life.

Of the three main topics, the authors devote the most attention to the first, and it’s here that their arguments are strongest and most clearly supported by the archaeological evidence. The key change in food production during the period in question is the intensification (not introduction) of maize agriculture as the primary subsistence activity, supplemented by the growing of other crops like beans and squash, by the raising of domesticated turkeys, and by hunting and gathering of wild foods. Recent research has clarified the sequence and extent of this change, although a lot of questions still remain.

As the authors note, one of the most puzzling results of research on early agriculture in the northern Southwest is that maize is now clearly established as having been introduced as early as 2000 BC in several widely spaced parts of the Colorado Plateau (including Chaco Canyon), but for hundreds of years it appears to have remained a minor part of the diet of the groups that used it. It was only in the Basketmaker II period, between 300 BC and AD 300, that maize use became widespread, and even then, according to Wilshusen and Perry, local groups varied widely in the contribution of maize to their diets. There may have been a distinction between immigrant groups from the south that had a heavily agricultural subsistence base and local hunter-gatherers who were gradually incorporating some farming into their lifestyles.

This slow and incomplete adoption of agriculture is in contrast to the situation in other parts of the world where agriculture, once introduced, spread rapidly and quickly replaced hunting and gathering. It’s still not clear why, although Wilshusen and Perry note that as a tropical plant originating in Mexico, maize would have been poorly suited for the harsher climate of more northern latitudes, and that it would have taken some time for people to breed hardier varieties. It is also apparent that the variety of maize initially introduced was small and not as obviously superior to local wild plant foods as later varieties, and that it was initially introduced without an accompanying “package” of other domesticated foods, as was the case with agricultural spreads in other areas. Domesticated squash seems to have been introduced not long after maize, but separately, and domesticated turkeys appear to have been introduced from a different direction altogether, although the timing and details of their domestication remain very murky.

Be that as it may, the main point Wilshusen and Perry make in regard to this slow adoption of maize is that it is likely that women, who based on cross-cultural studies of hunter-gatherers tend to be responsible for gathering of plant foods, were involved in the initial use of maize in the northern Southwest. However, this small-scale introduction of a new food, even one associated with a new type of food production, probably wouldn’t have had a major impact on existing gender roles or division of labor. That would come later.

The full “Neolithic package” appears to have arrived in the northern Southwest between AD 300 and 600, with components including a larger, more productive variety of maize known as Harinosa de Ocho; beans, newly introduced from the south; greater use of turkeys for both meat and feathers; and greater investment in facilities for food storage and processing. The greater productivity enabled by these innovations led to rapid population growth and the spread of agricultural groups over the landscape, in striking contrast to the lack of such growth with the initial introduction of maize much earlier. Wilshusen and Perry associate these developments with the transition from Basketmaker II to Basketmaker III, as well as with the major changes in the roles of women that they document.

Additional support for these changes in food production come from complementary changes in storage facilities and grinding tools. As documented in the well-studied Dolores area, the importance of storage seems to have risen over the course of the late Basketmaker III and Pueblo I periods from AD 650 to 875. Storage facilities changed from small pit rooms isolated from the main dwellings to more secure and more solidly built storage rooms directly attached to living rooms and only accessible from them. These typically consisted of two storage rooms at the back of each living room, the beginning of the “suite” layout that would continue to be a key architectural feature into Chacoan times. It is possible that at least initially these paired rooms were used to store two years’ harvests, one in each room, so as to provide a subsistence buffer against drought and other unexpected problems.

There was also a shift over this period in grinding implements from basin metates with one-handed manos to much more efficient trough metates with two-handed manos. Beyond this shift, a greater variety of grinding tools became common over time. Together with the storage data, this indicates an increased importance of grinding as a component of food preparation. In the modern Pueblos grinding is a female-associated activity, part of an overall suite of food-preparation tasks accomplished by women that also includes shucking, shelling, drying, and storing corn. Of these tasks, however, grinding is considered particularly important to the female role, and it is an important part of female puberty ceremonies (of which the Navajo Kinaaldá, of clear Pueblo origin, is probably the best known). Men, on the other hand, are responsible for planting and harvesting the corn, as well as protecting the fields. This seems to be a change from the presumed hunter-gatherer system in which women were generally responsible for gathering plant foods as well as processing them, and Wilshusen and Perry suggest that it may have arisen in early Pueblo times as fields at greater distances from residence locations in villages became increasingly vulnerable to attack by enemies, prompting men’s role as warriors to encompass guarding fields and, in time, tending them as well.

Another important female task in modern Pueblos is making pottery, and this too seems to have become increasingly important with the expansion of agriculture in early Pueblo times. With more use of crops and additional cultigens such as beans, pots would have become more important for food preparation, and with the number of vessels needed and their short use-lives of 1 to 6 years women would have had to be constantly making new ones. (This is of course assuming that most pots for domestic use were made by the family unit itself, which may well be true for this early period but was not necessarily later on.) Based on detailed study of an isolated Pueblo I hamlet in the Central Mesa Verde area, Wilshusen and Perry estimate the following assortment of vessels for a typical household at any given time:

  • 2 to 7 small cooking jars
  • 1 to 4 medium cooking jars
  • 0 to 2 large cooking jars
  • 1 bowl
  • 0 to 3 ollas for water
  • 2 to 3 other vessels
  • 10 to 20 sherds from broken pots used as containers or tools

Keeping a household supplied with all these pots would have been a major part of a woman’s domestic labor, in addition to the food processing tasks mentioned above, along with other major responsibilities such as caring for children.

And speaking of children, Wilshusen and Perry go on to discuss human reproduction and the apparent changes in it associated with the other changes they identify. The two main changes they note are shifts in the use of cradleboards and an apparent increase in the societal fertility rate. This part is somewhat less thorough than the food production part of the paper, but it does still identify some intriguing evidence for change.

First, cradleboards. The authors note that study of these items, in which infants were bundled while they were very young,  has been surprisingly limited, despite their relevance to an important event that has long been recognized: the beginning of evidence for “cranial deformation,” or the reshaping of skulls as a result of prolonged contact with certain kinds of cradleboards in infancy. The shift from “undeformed” to “deformed” (the terminology is very problematic, as there is no evidence of health problems from the practice) crania is traditionally associated with the transition from Basketmaker III to Pueblo I, and early in the history of Southwestern archaeology the change in head shape was even taken as evidence for a population replacement. (That was in the early twentieth century when anthropologists put much more emphasis on skull shapes in defining populations than they do now.) It is now generally thought that the distinction is actually due to the use of soft versus hard cradleboards, but recent research that Wilshusen and Perry discuss suggests that both types of cradleboards were present in both Basketmaker and Pueblo times. Thus, the shift in cranial shape is actual due not to a change in the type of cradleboard but in how it was used. The main changes that actually seem to have occurred in the Pueblo I period are:

  • Foot rests on cradleboards disappear.
  • Hoods become more common.
  • Construction is more expedient.

According to Wilshusen and Perry, these changes together indicate that women had less need to move while carrying children in cradleboards, but that they needed more cradleboards overall, possibly indicating that they had more children. This part of the paper does not go into much detail about where these conclusions come from, but the overall conclusions is that this is further evidence that women were more tied to the domestic sphere in Pueblo I, and possibly that they had more children.

On that note, demographic data appear to indicate that the population increases seen in at least some part of the Pueblo world during Pueblo I were due largely to natural increase after initial immigration into new areas. The best data come from the Central Mesa Verde and Eastern Mesa Verde areas, both of which seem to show this pattern. Prehistoric demographics are notoriously hard to reconstruct, but based on the large recent data sets from major excavation projects Wilshusen and Perry propose that a Neolithic Demographic Transition (a major increase in fertility associated with the beginning of intensive agriculture) began in the northern Southwest around AD 300, with major consequences over time for women in particular, given their gender-defined economic roles. This is comparable to evidence seen in other parts of the world with the beginning of agriculture. The key point here for the role of women is that with increasing rates of both childbirth and survival of children beyond infancy, families would have become larger, increasing the amount of domestic labor required of women to maintain their households given the gendered division of labor presumed to have developed. This would be one explanation for the increased importance of food processing mentioned above.

Finally, Wilshusen and Perry talk about exchange and social power. The discussion here is very abbreviated, and relies heavily on references to the next chapter in the book (which is a little odd), but the basic idea is that rock art evidence shows a shift in social power to male leadership of ritual in late Basketmaker III, continuing into Pueblo I. Female economic roles expressed in matrilocal residence may have driven men to make external trade alliances, which over time developed into new ritual systems focused on important lineages within villages rather than large public rituals at central places not necessarily associated with a specific lineage or community. Matrilineal lineages were still important, and the focus of key rituals, but changing gender roles may have involved an increased role for the men of the lineage in certain types of rituals. Burial evidence from Ridges Basin may support some of these ideas, with striking differences in male and female burials, particularly in the types of exotic goods included. Both women and men were buried with exotic items occasionally, but the specific types of items varied, suggesting gendered access to different trade systems. There are also geographic differences within the basin suggesting different community connections and ideological systems. This section is intriguing but very sketchy, even compared to the rest of the paper. More detailed discussion of some of these ideas will have to wait for the next chapter.

Overall, the conclusion of this chapter is that over the course of the early Pueblo period gender roles shifted in a way that evolved into the system(s) that are well known from the modern Pueblos. This may have been a response, in part to the demographic shift resulting from the development of intensive agriculture, with its resulting higher birthrates and changes to the roles of women. Women’s labor was key to this transition, but it’s not clear that it was actually good for women as a class on net. There has been some discussion of the idea of “parallel status hierarchies,” in which men and women had different tasks but both allowed meaningful status through high achievement. However, later evidence from Pueblo sites shows that women were often excluded from access to high-value resources such as meat, and that their graves were generally less elaborate than men’s (a contrast to the Pueblo I situation in at least some areas). It doesn’t appear that many strictly comparable studies of these issues have been done of the Pueblo I period itself, so it’s hard to say how these changes felt for the women who were living through them. The authors of this paper seem to lean toward thinking the changes were not actually beneficial for those women, but the evidence is thin enough that it’s not clear.

Above I have summarized the arguments of this chapter as best I could, but it’s worth noting that the argumentation of the chapter itself is highly abbreviated, and summarizing it has required a lot of assumptions and interpretive leaps. It kind of reads like this paper is an abbreviated version of a longer argument, with some important parts left out. Nevertheless, it raises a lot of interesting questions that have rarely been addressed in Southwestern archaeology, especially regarding the early Pueblo period, and for that alone it is valuable.

Watching the Sun

Walls at Wijiji

Today is the winter solstice, and the seventh anniversary of this blog. I’ve traditionally posted about archaeoastronomy on these anniversaries, so I’m going to briefly interrupt my series on Crucible of Pueblos to discuss an interesting article on the evidence for astronomical observations at Chaco Canyon. There turns out to be some overlap, actually, which is interesting.

The article is by Andrew Munro and Kim Malville, who were also the authors of the article on building orientations that I talked about last year on this date, and it was published in the same special issue of the journal Archaeoastronomy in 2010. The content is rather different however. This article summarizes the evidence for specific locations in and around the canyon for which there is evidence of use as solar observation “stations,” including two sites which are newly identified here. (Worth noting here is that Munro left a detailed and interesting comment on last year’s post, in which he linked to his unpublished thesis which contains more detailed and up-to-date information on his approach to archaeoastronomy. I haven’t read it yet, so I’m focusing here on the published articles while recognizing that they don’t have the most recent information.)

Identifying viewing stations is more complex than simply demonstrating alignments, for a variety of reasons. For one thing, based on modern Pueblo ethnography, sun-watching locations were not necessarily marked physically with architecture, rock art, or anything else. This makes their archaeological identification difficult, and probably means that the stations that did happen to have physical markers are probably over-represented.

Identifying these stations also requires careful consideration of how exactly the observation process would have likely worked, what its specific purposes were, and how they could have been met. If, as Munro and Malville argue, the main role of these observations was to fix the dates of ceremonies marking key times in the year, there would have been a practical need to mark not just the date of the ceremony itself, but dates leading up to it which would have given time to prepare for it. Munro and Malville use the term “anticipatory” for stations that would allow prediction of an event in advance, and “confirmatory” for those that would allow observation of the date of the event. There would also need to be a system for communicating the information from the observation stations quickly and easily to other sites in the canyon and beyond.

There is also an important distinction between observation stations and shrines. The former were used for the practical purpose of making observations, while the latter were associated with those observations but used for ritual activities rather than observation, and often were not in locations from which accurate observations could be made. Munro and Malville use the terms “primary” and “secondary” to refer to these different types of sites; secondary stations could include both shrines, which could involve rock art and/or simple architecture, and alignments within or associated with buildings. The well-known, though not universally accepted, alignments at Pueblo Bonito and Casa Rinconada would fall into the secondary category, as would the “Sun Dagger” petroglyph site atop Fajada Butte. In this paper Munro and Malville focus on the primary stations, which they further divide into two categories depending on whether they could be used both to predict significant dates in the solar calendar and to observe them when they occurred, or just to observe the occurrence. For practical purposes the former type would be more useful.

Despite Chaco’s reputation for astronomy, it turns out that good locations for primary observation are pretty rare in the canyon. One key requirement for such a location is a “broken” horizon with obvious landmarks that can be used to track the sun’s (or moon’s) progress along the horizon, but from most great houses the horizon is actually pretty flat and unsuitable for observation. This is presumably due to the flat mesa tops to the north and south of the canyon itself. The number of possible locations for observation stations is therefore reduced to a few areas of the canyon where the horizon is more varied. Munro and Malville list five previously documented stations and add two more based on their own research. (A few more have since been identified.) They are briefly described below.

Fajada Butte with Green Vegetation

Fajada Butte with Green Vegetation

Piedra del Sol is a large rock near the current Chaco visitor center that has a wide variety of rock art as well as multiple astronomical alignments. Of particular interest is an apparent viewing station for summer solstice sunrise associated with a large spiral petroglyph on the northeast face of the rock. The horizon as viewed from this spot could allow for both anticipatory and confirmatory observations for the solstice. Even more intriguing, the station has a direct line of sight to the “Sun Dagger” site on Fajada Butte, suggesting that this may have been the location from which the observations were made that allowed the spiral petroglyph at that site to be placed in exactly the right position for the “dagger” of light to pierce it on the summer solstice.

There are multiple identified observation stations in the area of the Wijiji great house at the eastern end of the canyon. One site, 29SJ931, is near a pictograph site on a ledge near the great house and allows observation of the winter solstice. There are some features at the site that are similar to the sorts of features found at post-Chacoan observation sites in the Mesa Verde area, as well as evidence for later Navajo use, so it’s not clear that this site was actually used at all during the Chacoan era. Another site near Wijiji, 29SJ1655, has many Navajo petroglyphs nearby but does also have Chacoan rock art and a possible shrine, suggesting Chacoan as well as Navajo use. This site actually consists of three siting locations, allowing observation of both solstices as well as both equinoxes.

More firmly established as a Chacoan siting station is the Wijiji great house itself. From the northwest corner of the building a notch is visible on the horizon that serves as both an anticipatory and a confirmatory marker for the winter solstice: about two weeks before the solstice the sun rises at the left edge of the notch, and on the solstice itself it rises on the east edge. Since Wijiji was one of the latest great houses to be built in the canyon, it’s possible that it was sited at a location already used as a solstice observation station. As we shall see, it is not the only great house for which this appears to be the case.

Kin Kletso

Kin Kletso

Further west in the canyon, another late great house, Kin Kletso, shows a similar alignment to the winter solstice, with both anticipatory and confirmatory observations possible but in a different way. Here, looking from the southeast corner of the building toward a nearby cliff about two weeks ahead of the solstice (the same dates as the Wijiji anticipatory alignment) shows the sun rising at the base of the cliff. Over the course of the next few weeks, the same sunrise alignment is visible by gradually moving north along the east wall of the site, until on the solstice itself the alignment is visible from the northeast corner. As with Wijiji, it is possible that Kin Kletso was built at the site of an existing observation station, perhaps associated with the large boulder at the western end of the site. (I mentioned both the Wijiji and Kin Kletso observation alignments in my very first post on this site, as it happens.)

In addition to these previously identified observation stations, Munro and Malville describe two new ones based on their own recent research. Both of these are interesting partly because of what they imply about the date at which these sorts of observations began at Chaco.

29SJ2539 is in the general area of Wijiji, and also near the important Basketmaker III village of Shabik’eschee. The site itself includes a boulder with an alignment allowing for confirmatory observation of the winter solstice sunrise through a notch at the foot of a nearby cliff, along with a wide variety of artifacts and rock art indicating both Chacoan and Navajo use. An immediately adjacent site, 29SJ2538, includes a ledge overlooking the boulder that could have been used for storage but apparently wasn’t. Another nearby site is a small-house habitation that was excavated by Frank H. H. Roberts in 1926, now known as “Roberts Small House.” This site was apparently occupied over a long span of time, from Pueblo I through the post-Chacoan “Mesa Verdean” occupation of the canyon. It contained a large number of turkey bones, giving it the alternative name of “turkey house.” It also contained human remains, including some that have been argued to show evidence of cannibalism. Christy Turner, who initially made the cannibalism claim, identified the remains as dating to early Pueblo II, but Munro and Malville cite more recent research showing that they were actually from an earlier Pueblo I context. They also argue that there is no reason to associate the cannibalism evidence with the evidence for astronomical observation or related ritual practices, but without going into detail.

Looking West from Peñasco Blanco

Looking West from Peñasco Blanco

Finally, Munro and Malville identify a possible observation point for winter solstice sunrise at Casa del Rio, an early great house just west of the canyon that seems to have been an important site in the Pueblo I period, with an exceptionally large trash midden suggesting possible feasting activity involving people beyond those living at the site. From this site (Munro and Malville don’t specify the exact viewing location) the solstice sunrise is aligned with West Point, the high point on the west side of West Mesa that contains a Chacoan shrine and has direct lines of sight to the Peñasco Blanco great house as well as to other shrines from which messages could be quickly sent throughout the canyon and beyond. This close association with the signaling network, in combination with the large amounts of trash (which seems to have been primarily domestic trash associated with food consumption, unlike the more complex contents of the later, more formal mounds associated with Chacoan great houses), implies that Casa del Rio may have been a location where people gathered for feasts and other ceremonies during the Pueblo I period, with at least some of the ceremonies tied to astronomical events such as the winter solstice (or the full moon nearest to it). In this scenario, inhabitants of Casa del Rio would have watched the sunrises over West Mesa to determine the dates of their festivals, then communicated those dates to others by signaling to the shrine on West Point, from which the signal could have been transmitted to many other places.

Speaking of signaling, Munro and Malville also discuss how it could have been done. Fires or smoke signals are possibilities, but another intriguing options would have been mirrors made of selenite, a mineral that can be polished to a high reflective sheen which is found in some natural outcrops in the Chaco area, including one near the observation site at 29SJ2539. Pieces of selenite were in fact found at 29SJ2539 itself, as well as at several other sites in the canyon.

Several interesting patterns emerge from the data compiled by Munro and Malville. First, the winter solstice sunrise appears to have been the most important astronomical event observed by the ancient Chacoans, at least judging from the viewing stations that have been identified so far. This is consistent with modern Pueblo ethnography, which similarly indicates the winter solstice as the most important event and sunrise observations as generally being more important than sunset ones.

Second, there is a strong association between possible viewing stations and so-called “Late Bonito” great houses, those built in the early AD 1100s toward the end of the period of Chacoan florescence, often in the so-called “McElmo” architectural style that is sometimes associated with influence from the north. The relatively standardized sizes and shapes of these great houses, as well as their short periods of construction, suggest an aggressive building program at this time that might have been associated with an attempt to reassert Chaco’s importance at a time when regional focus was starting to shift north to Aztec. Siting these buildings at locations already used as astronomical observation points, and designing them to incorporate aspects of such observation into the buildings themselves, may have been a way for Chacoan leaders to emphasize their esoteric knowledge and spiritual power at a time when it was being challenged.

Finally, and most interestingly from the perspective of the series of posts I’ve been doing lately, Munro and Malville provide tentative but intriguing evidence for astronomical observation points in and around Chaco Canyon beginning in the Pueblo I period. This would to my knowledge make this the earliest known evidence for detailed astronomical observation in the northern Southwest, and possibly in the Southwest as a whole (evidence for the Hohokam in southern Arizona is more ambiguous). That, in turn, provides further support for my theory that the rise of Chaco was enabled in part by the development of a new ideology in which astronomy played a major role.

In this regard it is interesting that one of the early centers for astronomical observation may have been Casa del Rio, which was one of the most important local centers during the late Pueblo I period when the great houses in the canyon proper were just starting to be built. As noted in my earlier post on Pueblo I in the Chaco area, it’s clear that at this time settlement was largely focused to the west of the canyon along the lower Chaco River, which may have been a conduit for migrants leaving the villages in the Dolores, Colorado area when they collapsed in the late ninth century. It may have been these migrants, bringing the lessons they had learned from their experiments in village life and adapting to a new and very different environment, who first began to pay careful attention to the sky, perhaps in an attempt to improve their prospects of survival in an area that is exceptionally arid even for the Southwest. If their initial adaptations were successful, as they appear to have been at least in some places, they may have begun to gain prestige and to attract additional migrants from various areas, who would have brought their own ideas and lessons learned. Astronomy may have been the development that united these people and allowed them to develop a new social order that would go on to underlie the spectacular achievements at Chaco that we see evidence of even today. And when that social order began to be challenged, for reasons that are still unclear, its leaders may have sought to revitalize it through a renewed emphasis on their astronomical knowledge in the form of the Late Bonito great houses.

Obviously this is all fairly speculative, but more and more evidence has been accumulating in recent years to focus and ground such speculation in solid data. Archaeoastronomical research has been a key part of this, and this article is an important contribution to the developing picture.

Foreshadow: Perishables

chacomuseumsandals

Plaited Sandals at Chaco Museum

Chapter nine of Crucible of Pueblos looks at perishable artifacts (i.e., those made of materials that are often not preserved in the archaeological record, such as yucca fiber, animal hair, and cotton) during the Pueblo I period. Written by Laurie Webster, one of the most prominent experts on prehistoric Southwestern perishables, this chapter functions partly as an inventory and description of all known perishables from Pueblo I sites, and as such it is highly technical in nature and not very accessible for a casual reader. For this summary, therefore, I will focus on the high-level conclusions that can be made about Pueblo I cultural dynamics and relationships from the perishable evidence, rather than the evidence itself.

Those conclusions are quite interesting, as it turns out, especially when it comes to the patterning of different types of artifacts. Webster covers several different types of artifact, but I will focus on two with the most interesting cultural implications: sandals and textiles.

First, however, a note about the data. As Webster notes, the Pueblo I period has historically been poorly represented in the perishable data compared to earlier and later period that are known for extraordinary preservation from caves and rock shelters, especially the Basketmaker II and Pueblo III periods. People made much less use of caves and rock shelters during Pueblo I, and as a result many more of their perishable artifacts have, well, perished, and those that do survive are mostly in poor condition. Indeed, most of the best-preserved Pueblo I perishables are from areas like Tsegi Canyon and Canyon del Muerto in northeastern Arizona where caves did continue to be used in Pueblo I, although the Pueblo I occupation in these areas is poorly understood and it is not always clear that artifacts assigned to Pueblo I by early excavators really do date to this period. Luckily, however, the nature of perishable artifacts means that they can be directly radiocarbon-dated, and Webster mentions several examples that have been and many more that could be.

With that caveat out of the way, sandals. These were generally made out of yucca fiber and appear to have been a key way people at the time signaled their cultural identity, based on the geographic patterning of different types, and they likely had symbolic importance as well at least for some groups, based on the elaboration of some examples, implying an immense amount of labor, as well as the depiction of sandals in rock art and the creation of clay effigies (often called “sandal lasts” although that doesn’t appear to have been their actual function). In particular, highly elaborate twined sandals were common in western areas during Pueblo I, a continuation of a tradition from Basketmaker times. Pueblo I examples are known from northeastern Arizona, the eastern slope of the Chuska Mountains in New Mexico, the Dolores area in Colorado, and Chaco Canyon. In contrast, only one example is known from the Animas River Valley, and none from further east, despite the large recent excavations in this area in conjunction with large development projects.

A different type of sandal dominates in these eastern areas, a twill-plaited design that appears to date back to the Basketmaker II sites near Durango, Colorado. This type dominates in the Ridges Basin and Blue Mesa area of the Eastern Mesa Verde region and is also found in the Navajo Reservoir area further south, as well as at Grass Mesa Village in the Dolores area. The last is particularly interesting given that there is other evidence that Grass Mesa was settled by people from areas further east. It is also interesting that McPhee Village, also in the Dolores area, shows mainly twined sandals, again supporting other evidence suggesting western connections for this site. Similarly, the one site in the Animas Valley showing evidence for twined sandals also has other evidence of western connections.

A third type of sandal, plain weave with a rounded or pointed toe, appears to also have a western distribution extending from southern Nevada to northeastern Arizona and southeastern Utah but not into Colorado or New Mexico. Less is known about this type than the other two and its cultural significance is not clear.

While in general Webster concludes that Pueblo I perishables mostly continue Basketmaker III patterns without major innovations, she does note one major innovation by late Pueblo I: the increasing use of cotton. While many of the cotton textiles from northeastern Arizona attributed to Pueblo I have questions about their dating and associations, there is one example of a sash from Obelisk Cave in the Prayer Rock District (extreme northeastern Arizona) that has been directly dated to the AD 700s (early Pueblo I). One particularly interesting thing about this sash is that it actually consists of a mixture of cotton and dog hair, clearly showing the transition from animal hair and cotton for textiles. While the form of this item and the use of mixed materials strongly implies that it was made locally, it is not clear if the cotton was in fact grown locally or imported from the Hohokam in southern Arizona, who had a well-established tradition of cotton agriculture by this time.

By late Pueblo I, however, there is strong evidence that at least some Pueblo groups were growing their own cotton. At Antelope House in Pueblo del Muerto, cotton cloth in contexts dating to the AD 900s was found along with cotton seeds and bolls, clearly implying that cotton was being grown in this area by then, as it continued to be throughout the Pueblo period. Interestingly, there is no evidence for Pueblo I use of cotton textiles further east, again implying some sort of major cultural boundary. This is in contrast to later periods, when cotton grown in northeastern Arizona was traded to various other parts of the Pueblo world.

So anyway, those are the major points of interest about Pueblo I perishables. I find the most interesting point from the perspective of Chaco to be the fact that it patterns with the western rather than the eastern style of sandal, which reinforces other evidence for western connections for at least some of the people who came to Chaco in late Pueblo I and contributed to its rise into a dominant regional center in the northern Southwest.

Foreshadow: Animal Bones

McPhee Reservoir, Dolores, Colorado

McPhee Reservoir, Dolores, Colorado

The first of the shorter, more analytical chapters in Crucible of Pueblos that follow the regional summaries is one by James Potter looking at faunal remains, which in this context basically means animal bones. (I guess this is sort of appropriate for a Halloween post, although animal bones aren’t really as spooky as human ones.) This chapter is basically a series of statistical comparisons of faunal assemblages from different Pueblo I sites, focusing particularly on the large, well-document collections from the Dolores and Animas-La Plata Projects, but also including a few others. Given the focus on these collections, the geographical range of these comparisons is limited to the Central and Eastern Mesa Verde regions. Nevertheless, Potter finds some striking differences between different sites that have interesting implications for understanding their inhabitants’ lives.

The first comparisons are of different villages within the Dolores area. Potter uses two widely used calculations, known as the artiodactyl index and lagomorph index, to compare McPhee Village on the west side of the Dolores River to Grass Mesa Village on the east side. The artiodactyl index is a measure of how common large game animals, such as deer and elk, are within the overall assemblage, and is calculated by taking the number of artiodactyl specimens in the assemblage and dividing it by the number of artiodactyl specimens plus lagomorph (rabbit and hare) specimens. The lagomorph index compares the number of specimens of the two most common lagomorph species, cottontail rabbits and jackrabbits, and is calculated as the number of cottontail specimens divided by the combined number of cottontail and jackrabbit specimens. This is an important measure because cottontails and jackrabbits favor different habitats and have different behavior which can shed light on human land use and hunting practices: jackrabbits prefer open spaces such as those created by clearing land for agriculture, and as a result can often be caught within gardens, while cottontails prefer more sheltered brushy environments. Jackrabbits also run to escape predation while cottontails hide, which makes the former more vulnerable to the kind of communal hunting known to have been practiced by Pueblo peoples in more recent times.

In the case of McPhee and Grass Mesa Villages both indices show little to no difference between the two; indeed they are nearly identical. This suggests that there weren’t major differences between the two communities in land clearing, communal hunting of lagomorphs, or hunting of artiodactyls. This is maybe not surprising, as the two villages are only a few miles apart and in similar ecological settings.

Where they do differ, however, is in another comparison, in this case of the prevalence and diversity of bird remains. McPhee Village has many more bird remains, representing more than twice as many species, than Grass Mesa, despite the overall sample sizes being similar. Furthermore, the avian bones are concentrated within McPhee Village at one particular residential site, known as McPhee Pueblo. This is one of the largest residences in the community and has features that have been interpret as reflecting ritual activity at a level higher than the individual residential group inhabiting the site. This site is considered likely to be a prototype of the “great houses” associated with the later cultural phenomenon centered on Chaco Canyon, where many of the inhabitants of the Dolores area are thought to have gone after the demise of the Pueblo I villages there in the late ninth century AD. The greater number of bird species, and the large number of specimens, at McPhee Pueblo reinforces other indications of the special role this site played in the community. Birds have often been associated with ritual among the Pueblos, with the macaws at Chaco being only one of the most spectacular examples. The fact that there is no similar site at Grass Mesa, and that bird remains are much rarer there overall, suggests significant differences in ritual organization at the two villages despite their proximity, which fits with other evidence suggesting they were settled by people from different cultural backgrounds.

The second major set of comparisons Potter makes addresses change over time, again within the Dolores area. He compares the artiodactyl and lagomorph indices of McPhee Village and the nearby but earlier community of dispersed hamlets known as Sagehen Flats. In this case, the Sagehen Flats sites had much lower artiodactyl indices, which suggests to Potter that this community had more difficultly organizing hunting parties to capture these large animals than the later, larger, and more aggregated community at McPhee. Indeed, it has been suggested that one reason for the formation of the large Pueblo I villages was the opportunity that larger communities provided for more effective hunting of large animals, especially in high-elevation areas close to large populations of artiodactyls.

Sagehen Flats also had a higher lagomorph index value, indicating more cottontails relative to jackrabbits, and suggesting that aggregation at McPhee also included more clearing of land for agriculture, creating the open spaces preferred by jackrabbits. It is also likely that larger communities were more effective at communal hunting, which as noted above would have been easier with jackrabbits. It’s not really surprising that larger communities would have cleared more land for agriculture and conducting larger communal hunts, but this evidence does provide another reason to think that.

Bird remains, on the other hand, were present in very similar proportions at both Sagehen Flats and McPhee, with both much higher than Grass Mesa. This likely results in part from the location of Sagehen Flats near marshes with lots of good habitat for waterfowl, but it’s also noteworthy that the bird remains there, as at McPhee, were heavily concentrated in one habitation site. This site, unlike McPhee Pueblo, doesn’t show other signs of having been exceptionally important compared to others, but it is highly intriguing that there were so many birds there, and it suggests that the pattern of unequal ritual influence seen at McPhee, and later at Chaco, goes back even further, at least in this area.

Next, Potter does a broad comparison of several different site areas, this time treating the Dolores sites as a whole and comparing them to the nearby hamlet of Duckfoot as well as the site clusters of Ridges Basin and Blue Mesa to the east near the modern city of Durango, as well as sites in the Fruitland area to the south near the modern Navajo Reservoir. Starting with the artiodactyl and lagomorph indices, Potter finds high artiodactyl index values at Dolores and Ridges Basin, with much lower ones at Duckfoot and Fruitland. The factors mentioned earlier leading to more effective artiodactyl hunting in larger villages are probably one factor here, with another being elevation, with the higher sites having more artiodactyls than lower ones.

The lagomorph index is highest at Duckfoot and Blue Mesa and lower at Dolores and Ridges Basin, again echoing the pattern seen before where larger villages show evidence for more land clearing and communal hunting compared to smaller, more dispersed sites.

Turning to birds, Potter finds the highest numbers in Ridges Basin, with significantly smaller numbers at Dolores and Duckfoot. (Keep in mind that all of the Dolores sites are lumped together here.) This is likely due in part to the marshy environment of parts of Ridges Basin, but it is also due to much more extensive use of turkeys in Ridges Basin than elsewhere.

Following these rather simple comparisons, Potter does a correspondence analysis of all of the areas comparing categories of animal remains: birds, wild carnivorous mammals, domesticated dogs, lagomorphs, and artiodactyls. This analysis shows that the areas have very distinct associations with particular types of animals. Blue Mesa, Fruitland, and Duckfoot are associated with lagomorphs, Dolores with artiodactyls, and Ridges Basin with both birds and dogs. Potter notes that while Dolores and Ridges Basin have very similar artiodactyl indices, as this analysis suggests, they have very different overall percentages of artiodactyls. The index is thrown off because it uses lagomorph numbers to standardize the artiodactyl numbers, which is problematic in cases like this because the number of lagomorphs also differs a lot between the two areas, with a lot fewer of them at Ridges Basin than at Dolores.

Next, Potter does a detailed analysis of the Ridges Basin community, comparing categories of remains among different site clusters within the basin. He uses a more detailed set of a categories here than in the previous analysis: mammalian carnivores, birds of prey, waterfowl, dogs, turkeys, game birds, artiodactyls, and lagomorphs. The different site clusters show interesting differences in the proportions of these, with the marshy eastern cluster having higher numbers of waterfowl and turkeys. As mentioned above, turkeys are more common throughout Ridges Basin than in other Pueblo I communities, but there are differences in both numbers and context within the basin. The turkeys in the eastern sites are mostly burials, part of a widespread Pueblo practice of burying domestic animals that likely has ritual significance. In some site clusters, however, there is evidence for processing of turkey remains suggested they were used as food. In the north-central cluster there is one pit structure that seems to have been used as a processing area for turkeys and rabbits, and the same site also had turkey eggshells, suggesting strongly that these were domesticated rather than wild turkeys.

Dogs, wild birds, and carnivorous mammals are found mostly as burials throughout Ridges Basin, with some accompanying human burials. This is in contrast to McPhee Pueblo, which as mentioned above had high numbers of wild birds, where remains of ritually important animals like these were found in association with ritual structures. There is no such association anywhere in Ridges Basin, suggesting that while these animals were likely ritually important in both areas, the exact nature of the associated ritual differed.

As for artiodactyls, here as elsewhere they were found in greater numbers at the only aggregated site cluster that can be considered a village: Sacred Ridge. Since this site also has higher numbers of projectile points and processing tools, Potter suggests that the artiodactyls were the result of more effective hunting parties drawn from the larger village population, rather than evidence for special status of the residents of Sacred Ridge or special feasting being conducted there. There are a lot of unusual features to this site, however, so it’s hard to know how to interpret it.

That concludes Potter’s analyses. He ends the chapter with some conclusions that they suggest. First, as seen in multiple analyses, large sites tend to have more artiodactyls than small ones, probably because larger, more aggregated settlements allowed for the building of cooperative hunting parties that were more effective at taking down large game. This was a definite material advantage to community aggregation and the formation of villages, a key characteristic of the Pueblo I period that has led to a lot of questions about why and how it happened. It’s noteworthy, however (although Potter doesn’t note it) that the Pueblo I villages were as a rule short-lived and many seem to have been abandoned under duress, so the greater cohesiveness that allowed for these more effective hunting parties seems to have had definite limits under the circumstances.

Another pattern that emerges is the association of some sites with marshes and the extensive use of waterfowl, and presumably other marsh resources, at these sites. Potter connects this with the general importance of marshes, lakes, and other water places in Pueblo religion and ritual, as well as with the later artificial reservoirs built in the Mesa Verde region. It’s possible that an initial tendency to settle near wetlands because of their practical advantages in terms of resources led over time to a more metaphysical attitude toward watery places, although this remains highly speculative.

There is also a tendency over time for a shift in the contexts in which remains of animals of presumed ritual significance, like wild birds and carnivorous mammals, with early sites such as those in Ridges Basin having them largely associated with burials and the ceremonial “closing” of residential sites, whereas at later sites such as those in the Dolores area they are more associated with communal ritual structures. This suggests a shift in use of these religious symbols from the private to the public sphere, which Potter notes has also been proposed over the same period for the use of red ware pottery, which also likely had ritual significance. This shift may have continued into the rise of the Chacoan system, with its increased focus on monumental architecture presumably associated with public ritual.

Finally, Potter notes the early importance of turkeys in Ridges Basin, which could be due to general environmental differences across the region but may also reflect earlier depletion of large game in this area compared to others. There is a general pattern through Pueblo prehistory of increasing use of turkeys for meat as artiodactyl use declines, presumably in response to overhunting of local populations. On the other hand, one intriguing thing about the greater use of domesticated turkeys at the eastern edge of the Mesa Verde region during Pueblo I is the genetic evidence showing that domestic turkeys in the Southwest are likely more closely related to wild subspecies found to the east than to those found locally. Could the use of turkeys in Ridges Basin reflect early contacts with peoples further east? Potter doesn’t mention this possibility, and I don’t know if there is any other evidence of such contacts, but again, intriguing.

So, yeah, this chapter is a lot more focused than those coming before it, but the results of its analyses are intriguing. As more evidence becomes available from other regions with Pueblo I populations it may be possible to extend these sorts of comparisons further.

Foreshadow: The Rio Grande

Rio Grande from Coronado State Monument, Bernalillo, New Mexico

Rio Grande from Coronado State Monument, Bernalillo, New Mexico

Chapter seven of Crucible of Pueblos brings us to the final geographical region covered by the volume: the Rio Grande Valley, at the eastern edge of Pueblo settlement for the period in question. As it happens, I’m currently visiting my mom in Albuquerque, so I’m actually in this region as I write this. (Today also happens to be my birthday; I’m 31.) The chapter is by Steven Lakatos and C. Dean Wilson, and in a lot of ways it echoes an earlier paper by Lakatos about the Rio Grande Developmental Period that I have discussed before. This chapter, however, discusses only the Early Developmental Period, defined as AD 600 to 900, and primarily focuses on the part of the region that the authors called the Middle Rio Grande Valley, defined as lying between the Rio Puerco of the East on the west, the Sandia and Manzano Mountains on the east, the Isleta area on the south, and the La Bajada escarpment on the north. This is because agricultural populations only occupied this restricted area of the region during the Early Developmental, expanding north of La Bajada only after AD 900 when there was a huge increase in regional population at the beginning of the Late Developmental Period.

The key point Lakatos and Wilson make about the Rio Grande is that the Early Developmental period was a time of low population density and gradual growth, with little change in material culture over hundreds of years. This is in striking contrast to the “boom-and-bust” pattern now richly documented for the Mesa Verde region during the contemporaneous Pueblo I period there. The picture of continuity is reminiscent of that proposed by the authors of the previous chapter for the Little Colorado region, but it’s worth noting that the major data gaps that plague the study of that region are less of an issue for the Rio Grande, which has a long history of intensive archaeological research continuing to the present day. Furthermore, Lakatos and Wilson present several lines of evidence supporting their conclusions, which seem pretty solid to me. Based on this evidence, it really does seem like the Early Developmental was a time of low population, slow growth, and cultural continuity.

As Lakatos and Wilson note, this is actually a rather surprising conclusion in the context of many theories about early agricultural societies. Most strikingly, there is no evidence here for a “Neolithic Demographic Transition,” in which the increased productivity of agricultural societies compared to hunter-gatherers leads to massive growth among early agriculturalists, with all sorts of ecological and social consequences. Some have argued that the Mesa Verde boom-and-bust cycle is a result of this process. In the Rio Grande, however, the adoption of agriculture does not seem to have resulted in this sort of population growth. This is definitely not for lack of arable land, as the Rio Grande Valley is one of the richest agricultural areas in the northern Southwest, and it was intensively farmed later in prehistory and into historic times. Rather, Lakatos and Wilson argue that the richness of the Rio Grande environment allowed for a mixed farming-foraging economic pattern with high residential mobility, in contrast to the more agriculture-dependent societies further west. The greater importance of foraging versus farming is supported by evidence from faunal assemblages and wear patterns on human remains, and the mobility by the fact that residential pit structures were rarely remodeled.

In keeping with low density and high mobility, the settlement pattern consisted of scattered hamlets, with only occasional evidence for “communities” of hamlets loosely grouped together with possible communal architecture such as “protokivas” or oversized pit structures. Sites were mainly located along the major rivers of the region: the Rio Grande itself, the Rio Puerco of the East, the Jemez. Architecture consisted of residential pit structures and surrounding activity areas, generally oriented toward the east or southeast (perhaps oriented to the winter solstice).

Rio Grande people also appear to have been in closer contact with remaining hunter-gatherers than populations further west. It’s not clear if Early Developmental populations resulted from the adoption of agriculture by existing hunter-gatherers in the Middle Rio Grande Valley or if there was some migration of already agricultural populations involved, but in any case the areas north of La Bajada and east of the Sandias/Manzanos were definitely still occupied by hunter-gatherers during this period, and it’s clear that there was a lot of contact between the two groups. This may have contributed to the greater importance of foraging to Early Developmental people and their differences from other Pueblo populations.

Sandia Mountains from Tent Rocks National Monument

All that said, the Early Developmental people definitely were part of the Pueblo cultural tradition, and their material culture shows a lot of connections to populations to both the west and south. This is particularly true of pottery, which was dominated by plain gray ware similar to that of late Basketmaker groups on the Colorado Plateau, but with small amounts of a decorated white ware, San Marcial Black-on-white, which shows stylistic influence from Mogollon populations to the south but with technological characteristics more like those of early white wares to the west. Lakatos and Wilson mention one model of Southwestern prehistory under which early “strong patterns” of material culture originated in the San Juan Basin (ancestral to the Chaco system) and in the river valleys of the Mogollon region, with the Middle Rio Grande forming a “weak pattern” with influences from both but in varying combinations.

The clear picture that emerges from this is of a small population of forager-farmers moving around within the Middle Rio Grande area but maintaining their basic cultural features with little to no change for about 300 years, from AD 600 to 900. Then, in a development that is likely very important but poorly understood, there was a massive increase in population at the same time that agricultural groups for the first time began to occupy the higher areas about La Bajada. Lakatos and Wilson note that the timing of this change, while not as precise as might be ideal, seems to correspond closely to the collapse of the late Pueblo I villages in the Mesa Verde region and the major population movements involved with the depopulation of that area, including the apparent influx of people into the Chaco Basin that likely laid the groundwork for the Chaco Phenomenon.

It seems very plausible that the increase in population in the Rio Grande was linked to these developments, though exactly how is unclear. Material culture actually remained fairly stable and consistent with Early Developmental patterns across this transition, although architecture did become more standardized and San Marcial Black-on-white was replaced by Red Mesa Black-on-white as the main decorated ceramic type. The latter change, especially, suggests influence from the west, as Red Mesa is the main decorated type in the Chaco area and other parts of the southern Colorado Plateau during this same period. It’s possible, as Lakatos and Wilson suggest, that the increased population in the Chaco Basin directly spurred Middle Rio Grande populations to move northward, although it’s not clear how exactly this would have worked. Other possibilities are that populations from the intermediate areas, such as the Puerco of the East, began to move eastward in the Rio Grande Valley as a result of the population movements immediately to the west of them, perhaps pushing existing Rio Grande populations north, or that western populations were moving directly to the Northern Rio Grande area above La Bajada, “leap-frogging” existing populations in the Middle Rio Grande.

The fact that material culture continued to show local Rio Grande features throughout the region, however, suggests that some level of assimilation or cultural accommodation between the locals and immigrants was involved, rather than a more directly confrontational situation. It’s noteworthy that Lakatos and Wilson don’t discuss evidence for warfare or defensive features at all, which of course doesn’t mean those things didn’t exist but does suggest that they may have been less prevalent than in some other regions.

Turquoise-Encrusted Cow Skull, Santa Fe, New Mexico

Turquoise-Encrusted Cow Skull, Santa Fe, New Mexico

Another thing Lakatos and Wilson don’t discuss, but which seems particularly important to understanding these relationships, is turquoise, specifically that from the well-known mines in the Cerrillos Hills east of the Sandias. Turquoise is of course strongly associated with Chaco, and while not all of the turquoise there has turned out to be from Cerrillos, a substantial portion of it definitely was. Evidence for increased connections between the San Juan Basin and the Rio Grande area at the same time as the rise of Chaco as a regional center is very intriguing in this light. Could increasing demand for turquoise at Chaco have led to the Cerrillos mines being a “pull” factor leading western groups into the Rio Grande Valley? Could the mines have even led local Rio Grande groups, or mixed groups of locals and immigrants, to move further east, across the mountains and even up over La Bajada into the Santa Fe area, which may have become more attractive as increased immigration reduced the supply of land in the Middle Rio Grande? And what about those remnant hunter-gatherer groups east of the Sandias and north of La Bajada? What happened to them? Were they attacked and defeated by the encroaching farmers? Pushed out into areas further north and east? Assimilated into agricultural society, which even in the Late Developmental period had a strong foraging component? There are a lot of questions about this period in this area, and very little evidence on which to base any answers. Lakatos and Wilson recognize this and suggest some research directions that would be helpful in answering the remaining questions, although they don’t point out as many as I have here.

Overall, this is a very informative chapter that brings into the discussion of Pueblo I societies an area that is often left out of these discussions. It’s an area of crucial importance for understanding regional dynamics throughout the northern Southwest, however, so I’m glad it was included in this volume. This chapter concludes the geographical summaries in the book; the remaining chapters cover various thematic topics of interest in understanding the Early Pueblo period as a whole.

Little Colorado River from Homol'ovi Ruins State Park

Little Colorado River from Homol’ovi Ruins State Park

Chapter six of Crucible of Pueblos brings us to the area immediately to the south and west of the areas previously considered. The region, which the authors call the Little Colorado after its main river, consists mostly of the drainage basin of that river but with some modifications. The southwestern part of the drainage around the modern town of Flagstaff, Arizona is excluded, as its culture history is quite different. Included despite being outside the Little Colorado drainage are the Chinle Wash area in northeastern Arizona and the Acoma area just across the Continental Divide in New Mexico. As the authors note early on, this region is geographically larger than all the previous regions in the book put together, but it makes sense to include it as a single chapter for several reasons. In addition to making it easier to track movement and changes across broad spatial scales, an important goal of this volume, considering this area as a whole helps to avoid some of the problems with considering its subregions separately, as is typically done. The Little Colorado straddles what have been considered the boundaries between traditional archaeological culture areas, and as a result its subregions have often been treated as peripheral to better-known areas rather than central in their own right. Particularly for understanding the Early Pueblo period (here defined as AD 600 to 925), however, it is useful to look at the Little Colorado region as a unit centered on the Rio Puerco of the West, which appears to have been the center of regional population for the period.

I say “appears” because another characteristic of the Little Colorado is that its archaeological record is not nearly as well understood as those of the regions to the north and east, especially for the early period. There are several reasons for this that the authors review:

  • Surface architecture was generally less substantial and pit structures were shallower than in other areas, so they are harder to identify in surveys.
  • Many parts of this region are very sandy and windy, so sites are often covered by large amounts of windblown sand to the extent that they can’t even be seen on the surface at all.
  • While there has been a fair amount of excavation in connection with individual salvage projects for infrastructure like highways, much of this work has been in areas without significant Early Pueblo occupation, and there have not been any major projects on the scale of the Dolores or Chaco Projects combining extensive excavation with a focus on cultural synthesis.
  • The regional ceramic sequence for the early periods is poorly defined and dated, making it hard to interpret the artifact collections that do exist from survey and excavation projects.

The authors suggest some ways to address these issues, and express a desire that this chapter serve as a starting point for synthesizing what is currently known about the Early Pueblo period in the Little Colorado region.

The overall picture they paint is of regional stability and gradual change over the centuries, which they note is quite different from the more dynamic picture emerging from work further north. This certainly is a plausible interpretation of the available evidence, but it’s worth noting (and they actually do) that a similar gradualist interpretation was also applied to the northern regions before the major excavation projects starting in the 1970s refined the picture. Could it be that the apparent gradual change in the Little Colorado is also due to the low resolution of the current data? The authors don’t discuss this possibility, but it jumps out at me.

Nevertheless, there are some differences between the Little Colorado and other regions that may well mean that developments here really were more gradual and stable. For one thing, there is strong evidence for the very early presence of maize agriculture (as early as 2000 BC) in several parts of the region, and evidence for irrigation canals in the Zuni area as early as 1000 BC. This earlier appearance of agriculture compared to areas further north isn’t necessarily surprising given its even earlier presence in the southern Southwest and Mesoamerica, but it does provide a potential reason that the arid but fertile river valleys of the Little Colorado drainage would have had more stability than the more marginal areas to the north and east.

With this regional background in mind, the authors give brief summaries of each of their subregions then address some of the key topics that are emphasized throughout the book. I will briefly summarize their summaries below.

Rio Puerco of the West and Train Tracks at Petrified Forest

Rio Puerco of the West and Train Tracks at Petrified Forest

As I mentioned before, the valley of the Rio Puerco of the West seems to be a key subregion during this period. Early Pueblo sites are rare in the upper valley, but are very common from the Manuelito area to Petrified Forest (where the Puerco flows into the Little Colorado). Basketmaker II and early Basketmaker III settlement (before AD 600) is concentrated around Petrified Forest at the western end of the valley, where there are large pithouse sites that seem to mainly consist of repeated seasonal occupation. Population increased dramatically in this area in early Pueblo I and continued growing more slowly through Pueblo II, with occupation largely by scattered individual households and small hamlets. Throughout the valley mobility seems to have been frequent and perhaps seasonal, with a wide variety of site sizes and types that makes the settlement pattern hard to determine. There are a few larger sites that may have been comparable to the early villages further north, but even these are diverse in size and structure and it’s not clear how many of them were actually permanent aggregated communities as opposed to sites occupied seasonally over the course of many years. Some of those sites that have been dated show continuity between Pueblo I and Pueblo II, in striking contrast to the depopulation of the Mesa Verde region at the end of Pueblo I. This suggests that the Little Colorado really did have a different history and that the appearance of continuity is not just due to limited data.

The authors include the Zuni and Acoma areas as a single subregion, divided into three “districts”: Lower Zuni, Upper Zuni, and Acoma. The Lower Zuni and Upper Zuni are those parts of the Zuni River valley downstream and upstream of the modern Pueblo of Zuni respectively. There has been a lot of survey in the Upper Zuni district in recent years, but much less in the Lower Zuni and Acoma districts. This is unfortunate for understanding the Early Pueblo period, when the Lower Zuni was the main area of settlement. This is probably linked to its proximity to the Puerco (of which the Zuni is a tributary), given the extensive occupation there described above. There were small populations in the Upper Zuni and Acoma districts during Pueblo I that expanded rapidly in Pueblo II. Large settlements were rare throughout the subregion during Pueblo I except in the Hardscrabble Wash and Jaralosa Draw areas of the Lower Zuni district. Hardscrabble Wash includes the important but poorly understood site of Kiatuthlanna, excavated by Frank H. H. Roberts in the 1920s, and there are a couple of large settlements along Jaralosa Draw showing continuity between Pueblo I and Pueblo II.

Northeastern Arizona, considered as a single subregion here despite its size and diversity, had only a small and scattered occupation during Pueblo I, in contrast to marked increases in population after AD 1000 in several parts of it. Despite its small size, the early occupation in some parts of this subregion such as Black Mesa shows evidence for substantial storage implying year-round sedentism, in contrast to the apparent mobility in the more densely populated Puerco Valley. It’s worth noting that Black Mesa is one of the areas with very early evidence for maize agriculture. Despite the low overall population, there were some large and apparently permanent sites during Pueblo I, some of which, especially on the Defiance Plateau, continued to be occupied into Pueblo II when they began to include great houses and other Chacoan features.

The final subregion is the Mogollon Rim Margins at the southern edge of the region. This area forms the boundary between the Anasazi and Mogollon culture areas as traditionally defined by archaeologists. It was relatively sparsely populated during Pueblo I, but some areas saw a substantial increase in population around AD 850. There were some large sites, but as in other subregions they are hard to interpret and it’s not clear how many of them were permanent villages rather than long-term seasonal occupations. As might be expected, many sites in this subregion show mixed pottery assemblages of “Anasazi” gray wares and “Mogollon” brown wares, but what this means in terms of population movements and contacts is hard to say given the sparse data available.

Turning to bigger questions, the authors make an attempt at reconstructing population dynamics but it is very tentative given the limited data. What it does seem to show is that the Puerco and Lower Zuni areas were important population centers throughout the Early Pueblo period, with the Defiance Plateau becoming an additional center late in the period. A more scattered but persistent population elsewhere in the region supplemented these centers throughout the period.

Public architecture mainly involved great kivas, which existed in this region throughout the Early Pueblo period and were often associated with larger settlements with large amounts of storage capacity, implying a role as community centers for a large area. There were also a few isolated great kivas without associated settlements, which are hard to interpret. Several of the communities with early great kivas also had later Chacoan great houses, another piece of evidence for the persistence of these places as important centers. Interestingly, the general pattern in this region is of continuity between Pueblo I and Pueblo II, with an abrupt break and change in settlement patterns (though not a regional depopulation) at the end of Pueblo II associated with the decline of Chaco. This contrasts with the Mesa Verde region, where there was an abrupt break and regional depopulation at the end of Pueblo I, a repopulation late in Pueblo II associated with Chacoan influence, and continuity between the Pueblo II occupation and later Pueblo III communities before the total and permanent depopulation of the region at the end of Pueblo III. It’s not clear what this implies about the culture history of the two regions, but it certainly is interesting.

There seems to be little evidence for violence in the Little Colorado region during the Early Pueblo period, again in contrast to the Mesa Verde region, although it’s worth noting that the available data is much more limited. Still, the generally small size of sites and lack of defensive settings or defensive features like stockades does suggest that, for whatever reason, things were generally more peaceful here.

Cultural diversity and migration have long been topics of interest in this region due to its position across traditional boundaries, but the authors argue that some lines of evidence that have been used in the past to assess cultural differences and connections, especially ceramic styles and pit structure architecture, could use a fresh look in the light of new theoretical approaches and the much larger dataset available from salvage projects. Again, the need for a new emphasis on synthesis and a broader perspective in understanding this region becomes apparent.

Overall, this was one of the most informative chapters in the book for me. This region is very important for understanding the rise of Chaco, given the apparent southern connections of some of the migrants who contributed to its rise, but it has remained much less understood than the well-studied areas to the north that contributed other migrants. This chapter shows clearly how much less is known but also how much potential there is to know more, and hopefully it will spur further investigations of these important issues.

Foreshadow: Chaco

Visitor Center and Fajada Butte from Una Vida

Visitor Center and Fajada Butte from Una Vida

Chapter five of Crucible of Pueblos brings us to Chaco Canyon and the surrounding area. This is an area of particular interest for me, and I presume for most readers of this blog as well. While the rise of Chaco in the tenth and early eleventh centuries AD was clearly a development rooted in earlier events, there has long been less information available for the area of Chaco itself than for the areas to the north that have seen extensive relatively recent excavations of sites dating to the Pueblo I period. The Pueblo I occupations of those areas, the subjects of the earlier chapters in this book, are now fairly well understood, although there of course remain a lot of questions and gaps to fill. Further south the picture is still much murkier.

This chapter is written by prominent Chaco specialists Tom Windes and Ruth Van Dyke, and is particularly important and useful because it includes the first published synthesis of the work Windes has been doing for many years to identify sites in and around Chaco dating to the Pueblo I period. This work was written up as part of the series of reports on the work of the Chaco Project, but that report, dated 2006, remains unpublished. I presume that this is a deliberate decision on the part of the National Park Service to keep sensitive information on site locations from becoming public (although I don’t actually know for sure). This chapter, then, appears to serve as the published record of this important work, which significantly alters the conventional interpretation of Pueblo I in Chaco.

The authors define their geographic scope as what they call the “Chaco Basin,” which is essentially equivalent to what is commonly know in the Chaco literature as the “San Juan Basin.” I think this is a useful change to the terminology, since “San Juan Basin” in the hydrographic sense refers to a much larger area than it is used for in this context, and while some use terms like “San Juan Physiographic Basin” to clarify this, it’s more straightforward to redefine the area and use a new term. “Chaco Basin” is a good term to use because the area more or less corresponds to the drainage basin of the Chaco River, including its tributaries, although it extends a bit beyond to the east and south into the Puerco Valley and Red Mesa Valley respectively. However it’s labeled, this region is roughly bounded by the San Juan River to the north, the Chuska Mountains to the west, the Zuni Mountains to the south, and the Jemez Mountains to the east.

Temporally, the authors restrict their attention in this chapter to the period from AD 700 to 925, unlike some other authors in this volume who also address the preceding Basketmaker III period. This is understandable but in some ways unfortunate, since there was an important Basketmaker III occupation of Chaco Canyon that was likely important in setting the context for Pueblo I developments, just as those developments were important in setting the context for Pueblo II. Confusingly, they use the term “Pueblo I” for sites dating from AD 700 to 875 and “late Pueblo I” for sites dating from AD 875 to 925. As we’ll see below, the distinction between these two periods is important in this region, as population and settlement patterns changed significantly at around AD 875. The specific terms they use still seem odd and liable to cause confusion, however.

Part of the reason the authors argue that the Pueblo I occupation in this region is poorly understood is that the ceramic chronology is different from that of the better-known sites to the north, and using the same types to identify time periods for sites in both regions leads to problems. They carefully define the types they use to identify sites to time period, and also use architectural criteria (which are however difficult to apply to unexcavated sites).

Most of this chapter is a summary of what is known about Pueblo I settlement in each subregion of the Chaco Basin, based in large part on hitherto unpublished fieldwork. As a result, I will structure this post according to the same subregions in the same order and summarize the information on each.

Northern and Northeastern Areas

The heading for this section says “Northwestern” rather than “Northeastern,” but it’s clear from the text that this in error. These areas, north and northeast of the Chaco River but still within the drainage of the San Juan, were sparsely populated throughout the Pueblo period. Windes and Van Dyke note that the Largo and Gobernador canyons, to the northeast of Chaco, may have served as conduits for populations migrating south from the Mesa Verde region into the Chaco Basin in late Pueblo I. A recently discovered village at the confluence of Largo and Blanco Washes included a great kiva and at least 22 habitation sites, with tree-ring dates from the great kiva pointing to construction at about AD 828. This area is roughly due south of the Cedar Hill and Ridges Basin areas of the Animas Valley, considered part of the Eastern Mesa Verde region in this volume, which had extensive but short-lived populations early in Pueblo I. The tree-ring dates from the Largo-Blanco village suggest that it may have been associated with the initial migration out of the Ridges Basin/Durango area in the early 800s rather than the larger migration in the late 800s. The Chaco River may have been another conduit for migrants from the north, as Windes and Van Dyke note that surveys have found a major increase in sites dating to the late 800s along the east side of the Chaco, compared to a virtual absense of sites for earlier in Pueblo I. This will be a recurring pattern in the region.

Chaco Canyon Proper and Environs

The initial survey work of the Chaco Project in the 1970s identified a fairly extensive Pueblo I occupation in and around the canyon, and publications from that time posited a gradual increase in population over the course of Pueblo I leading up to the florescence of Chaco as a regional center in Pueblo II. Based on his more recent work with ceramic classification and dating, however, Windes disputes this account. He argues that the number of sites assigned to Pueblo I in those surveys is vastly inflated, and that for most of the Pueblo I period the Chaco area had a small population which increased dramatically, presumably due largely to immigration, in the late Pueblo I period. In this chapter Windes and Van Dyke (though clearly this part is mostly Windes) summarize the results of Windes’s reevaluations of the Pueblo I occupation in and around the canyon, moving from east to west.

Pueblo Pintado Great House at Sunset

Pueblo Pintado Great House at Sunset

At the east end of Chaco Canyon, the Pueblo Pintado area was apparently unoccupied until about AD 875, when it was colonized by two groups who had markedly different material culture and appear to have come to the canyon from different directions. They formed separate site clusters about 3 km apart, north and west of the later great house of Pueblo Pintado.

The first cluster, located just north of the great house, includes one exceptionally large roomblock more than 50 meters long, accompanied by a trash midden that is also unusually large. Based on the temper of early ceramics in this cluster, the people appear to have come from the Mesa Verde region to the north, presumably as part of the mass exodus following the collapse of the Dolores villages in the late ninth century.

The second cluster, 3 km west of the first one, appears to have also been founded around AD 875 but continued in use well into the Pueblo II period. The ceramics are quite unusual in manufacture for the Chaco area and indicate origins to the south in the Mt. Taylor area. Interestingly, the roomblocks in this cluster were aligned along the road connecting the Pueblo Pintado community to the core area of Chaco Canyon, implying that this road may date to the late Pueblo I period.

Moving west, the next major cluster of Pueblo I sites is what is known as the Chaco East community, which also featured a later great house. This area also appears to have been unoccupied until about AD 875, when it was colonized by a group occupying small residential sites, possibly only seasonally. In the 900s the community grew considerably, and initial construction of the great house may date to this period, although it’s impossible to tell for sure without excavation.

Third-Story Walls with Type I Masonry at Una Vida

Third-Story Walls with Type I Masonry at Una Vida

Fajada Gap, at the eastern end of the main concentration of sites in Chaco during Pueblo II, is one of the areas where early surveys indicated a dense Pueblo I occupation which Windes disputes based on current understandings of the ceramic chronology. In fact, while there was unquestionably a small occupation of the area throughout Pueblo I involving scattered hamlets, this appears to be yet another part of the canyon where there was an influx of people in the late 800s who established the basis for the community that developed subsequently. There are two great houses in this community, Una Vida and Kin Nahasbas, both of which were constructed beginning in the late ninth century.

The largest Pueblo I (pre-875) settlement in the Chaco area is actually outside the canyon, along the South Fork of the Fajada Wash. This community contained 26 sites in an arc along the west side of the South Fork; no contemporary sites are present on the east side. The community is loosely clustered around a complex of four roomblocks which were connected by a short road to a great kiva, and it likely included about 230 people overall. Its main occupation was around AD 800, making it contemporary with the earlier villages in the Mesa Verde region, but the layout of the community is more like later villages such as those at Cedar Hill and in the Largo drainage. (The description of the community in this chapter is very confusing and it’s hard to tell in what respects it’s being described as similar to or different from villages in other regions.)

Many of the potsherds from the South Fork community were tempered with chalcedonic sandstone, which is typical of sites to the south near the modern community of Thoreau. There is also an unusually high abundance of yellow-spotted chert among the chipped stone assemblage, again indicating connections to the south. This type of chert occurs in the Zuni Mountains near Thoreau and is common in sites in that area.

Although this was the largest Pueblo I community in the Chaco area, it appears to have been very short-lived, with little trash accumulation. This suggests that the Pueblo I period was a dynamic time of extensive population movements in this area just as it was in the better-understood areas to the north. The subsequent Pueblo II occupation of the South Fork was much more extensive than the Pueblo I occupation and quite different, with sites dispersed up and down the valley rather than clustered in one area. A similar though somewhat smaller cluster of sites dating to the Pueblo I period was also present in the upper reaches of Kin Klizhin Wash to the west of Fajada Wash.

Old Bonito

Old Bonito

Returning to the main canyon, there were a few scattered Pueblo I hamlets between Fajada Gap and South Gap, but the occupation doesn’t seem to have been extensive. Even in South Gap itself, an area of considerable density during Pueblo II and the location of the cluster of great houses known as “Downtown Chaco,” Pueblo I occupation was sparse, with a few scattered sites in the gap. Apparently the only Pueblo I site known in this part of the canyon proper is Pueblo Bonito, where the earliest construction of the great house, known as “Old Bonito,” dates to the mid-800s (or possibly even earlier) and there is also an earlier pit structure excavated by Neil Judd in the 1920s. Judd thought the pit structure reflected an earlier occupation unrelated to the great house, but with improved dating showing that the great house was begun earlier than had been thought the idea of continuity is beginning to seem more likely.

There is no evidence for Pueblo I occupation between South Gap and the mouth of the canyon, possibly on account of flooding creating an intermittent lake on the canyon floor. At the mouth of the canyon itself, the Peñasco Blanco great house, begun in the late 800s, sits atop West Mesa, and right next to it is the important Basketmaker III village of 29SJ423. The period between these two important occupations, however, appears to have involved only minor settlement, although there are a few scattered Pueblo I sites. Just west of the mouth of the canyon, however, is Padilla Wash, which had a substantial Pueblo I occupation (possibly even more extensive than current records indicate, since many Pueblo I sites may have been misclassified as Basketmaker III in earlier surveys), another example of the main centers of Pueblo I population in the Chaco core being outside the canyon proper. Windes and Van Dyke note that Peñasco Blanco may have been an important focal point for migration into the canyon from the west and north during late Pueblo I, and that it was likely more important than Pueblo Bonito at this time.

The Chaco River

As noted above, the Chaco River (formed by the confluence of the Chaco and Escavada Washes at the mouth of Chaco Canyon) was likely one of the main conduits for migrants from the north, but it was much more than that. Pueblo I communities existed all along the Chaco and its tributaries, and some of these communities included early great houses that would have been influential in the development of the great house phenomenon that found its greatest expression in Chaco Canyon in the eleventh century. Windes and Van Dyke discuss a number of these communities, based on field research by Windes to reevaluate areas identified by early surveys as Chacoan outlier communities and to look for evidence of Pueblo I settlement and early great houses.

Just west of Padilla Wash is Kin Klizhin Wash, which was the site of extensive Pueblo II occupation but only has a few Pueblo I sites aside from the cluster at its upper reaches mentioned above. There is a late Pueblo I great kiva known as Casa Patricio in the upper part of the drainage, accompanied by a number of late Pueblo I residential sites; it’s not clear from the writeup here what relationship this site cluster has to the earlier Pueblo I cluster.

Just downstream from the mouth of Kin Klizhin Wash is the very important early site known as Casa del Rio. While this was initially labeled a large Chacoan great house, reexamination indicated that it is actually a composite of two building stages, both relatively early, with much of the bulk of the structure provided by a Pueblo I roomblock measuring 112 meters in length, with a later masonry great house built over the central portion beginning in the late ninth century. The early roomblock is by far the largest in the Chaco Canyon region, more than twice the length of the earliest construction stage at Pueblo Bonito, and it is estimated to have housed about 16 households or 88 residents. Windes and Van Dyke describe it as “reminiscent of those north of the San Juan River,” although again it is not clear what specific characteristics this refers to. A large number of food preparation tools were found in the area, although other residential sites are scarce. This was clearly an important site during the Pueblo I period which may have played a key role in attracting migrants to the area.

Looking North from Kin Bineola

Looking North from Kin Bineola

One of the most important tributary drainages of the Chaco River is Kim-me-ni-oli Wash, which extends from the Dutton Plateau north past the current site of Crownpoint. The drainage of this wash includes several great houses and extensive Pueblo settlement, and it likely served as an important conduit between Chaco Canyon and areas to the south and southwest. The extent of Pueblo I occupation, however, seems to be unclear. Windes and Van Dyke mention large circular structures near the Bee Burrow great house that resemble Pueblo I great kivas, as well as small Pueblo I roomblocks in the same general area. The area around the Kin Ya’a great house at the upper end of the drainage appears to not have any Pueblo I occupation based on existing survey data, although there is a large Basketmaker III-Pueblo I site just west of Crownpoint and one arc-shaped roomblock near Kin Ya’a recorded as dating to Basketmaker III looks a lot more like a Pueblo I site. At Kin Bineola, site of a major great house dating to the early 900s or possibly slightlier earlier, there is a very small Pueblo I occupation that increased substantially after AD 875 as in many other parts of the region.

At the mouth of the Kim-me-ni-oli Wash near the current Lake Valley Mission there is a small cluster of Pueblo I sites “architecturally identical” to the South Fork cluster, with very sparse refuse indicating a very short occupation. A later occupation in the late 800s was more substantial, with three masonry roomblocks “sometimes portrayed as small great houses” and “enormous amounts of refuse” that Windes and Van Dyke describe as “excessive for normal domestic activities.”

Further down the Chaco drainage, the Willow Canyon area is unusual in showing evidence of both middle and late Pueblo I occupation in close proximity. The middle Pueblo I community consists of eight sites that show the typical “scattered hamlet” settlement pattern, while the eleven late Pueblo I sites are tightly clustered and associated with a large amount of refuse, leading the authors to interpret this as “a large group” that immigrated into the valley together. These sites show unusual amounts of Type I masonry, associated with later great house construction, although the authors declare that there is no “obvious” great house. It’s not clear what definition of “great house” they are using here, as one site in particular (known as the “House of the Weaver”) shows not only Type I masonry but a prominent mesa-top location with a broad view of the surrounding area, another common characteristic of later great houses. Another community south of Willow Canyon near the later Whirlwind great house also shows a similar pattern but has less information available. The Great Bend area, where the Chaco River turns from flowing west to flowing north toward the San Juan, also shows this pattern. The possible use of the river as a corridor for populations migrating from the north after the collapse of the Dolores villages makes this potentially an important area for understanding regional prehistory.

Chuska Mountains from Peñasco Blanco

Chuska Mountains and Chaco River from Peñasco Blanco

The eastern flanks of the Chuska Mountains, which parallel the north-flowing segment of the Chaco River and form the western side of its drainage basin, are also important for understanding Pueblo I settlement but are poorly known. The general pattern seems to be the same as elsewhere in the Chaco Basin, with a scattered occupation in early and middle Pueblo I that sees a huge increase, presumably from immigration, in late Pueblo I after AD 875, but due to depositional factors it’s likely that the earlier Pueblo I occupation has been underestimated. A few sites dating to this period have been excavated through salvage projects. Late Pueblo I sites are more common and seem to provide more evidence for the use of the river as a corridor from the north. The largest concentrations are in the Skunk Springs and Newcomb areas, both of which would become major Chacoan outlier communities in Pueblo II. At Newcomb, at least, there seems to be some evidence of a preexisting Pueblo I occupation. It’s not clear if there is any similar evidence at Skunk Springs, where the earliest stage of construction on the great house seems to date to late Pueblo I. Given the importance of Chuskan imports to Chaco at its peak, more research on the background of these communities would be helpful in understanding Chaco’s origins.

The Red Mesa Valley

The Red Mesa Valley is the area between the Dutton Plateau on the north and the Zuni Mountains on the south. It is topographically rather than hydrologically defined, and straddles the Continental Divide, with the western part drained by the Rio Puerco of the West and the eastern part drained by the Rio San Jose. This means it falls outside of the “Chaco Basin” as hydrologically defined, of course, but its culture history means that it makes sense to include it with areas to the north for purposes of this chapter. This valley was presumably an important travel corridor prehistorically, as it certainly was historically with the railroad and Route 66 running through it and remains today with Interstate 40.

Casamero Pueblo

Casamero Pueblo

This area has been the main focus of Van Dyke’s research, and it is clear that she rather than Windes is responsible for most of this section of the chapter. The same issues of ceramic identification as in the Chaco Basin make understanding the Pueblo I sequence here difficult, but the same basic pattern appears to apply as further north. Early in Pueblo I there was a small, scattered occupation, exemplified by a site on the mesa above the later Chacoan outlier community of Casamero. This site consists of at least two arcs of surface rooms fronted by five to seven pit structures, and resembles White Mound Village further west along the Puerco, which was excavated by Harold Gladwin in the 1940s and dates to the late 700s and early 800s. Another site like this from the same period was excavated near Manuelito during the construction of I-40 in 1961.

This sparse population expanded immensely in late Pueblo, when many of the later Chacoan great house communities were founded. Some of the earliest great house construction in the region took place in these communities, which Van Dyke has elsewhere used to argue that great houses were not initially associated particularly with Chaco Canyon specifically. The huge increase in population at this time seems to indicate immigration, but this chapter doesn’t address the issue of where the people in this area might have come from. Given the similarities to the communities to the north in the Chaco Basin, that seems like an obvious point of origin (with earlier origins probably further north in the Mesa Verde region), but developments to the south are poorly understood and can’t be ruled out as important factors. As noted above, some of the immigrants to Chaco Canyon and its surrounding area appear to have come from the south rather than the north, and southern origins would presumably be even more likely for the Red Mesa Valley populations given their location. The fact that the influx here appears to happen at the same time as the northern one is an interesting complication, however.

The Eastern Chaco Basin

This area, stretching from the area south of Chaco Canyon across the Continental Divide to the Rio Puerco Valley of the East, shows very little evidence for Pueblo I occupation. Today this is a very sparsely populated area used mainly for cattle ranching, primarily on private land, so there has been little archaeological survey, but what survey has been done shows very little prehistoric occupation at all. Only two exceptions are noted by Windes and Van Dyke. One is a recently discovered Pueblo I community southeast of Mt. Taylor, about which little is known. Detailed information from the survey that identified this community is apparently not going to be released. It’s not clear from the brief writeup if this has anything to do with the fact that the survey was for proposed uranium mining.

The other exception is the Puerco Valley of the East, around the later Chacoan outlier of Guadalupe. Here, survey by Eastern New Mexico University in the 1970s identified a “modest but scattered” Pueblo I occupation, which increased substantially in late Pueblo I and Pueblo II, culminating in the Guadalupe community with its apparently close connections to Chaco Canyon. Windes and Van Dyke note that the Puerco may have served as an important conduit connecting the Chaco Basin to areas further east, although it remains poorly understood. The eastern associations of Chaco are poorly understood in general, and this appears to be the case as much for Pueblo I as for Pueblo II.

Storm in the Distance through Fajada Gap

Storm in the Distance through Fajada Gap

After going through the detailed geographical summaries, the authors briefly address some region-wide issues important for understanding the patterns they describe. They acknowledge environmental factors as probably important in understanding population shifts, pointing in particular to an apparent “spike” in rainfall in the immediate area of Chaco Canyon between AD 885 and 905 that might have served as a “pull” factor bringing people in from other areas. Conditions in the Chuskas and Red Mesa Valley appear to have been generally unfavorable during this period in which they, too, saw significant immigration, so clearly rainfall totals weren’t the only factor.

They also discuss violence, noting that there is very little evidence for it in this region, particularly in the central Chaco Basin, during Pueblo I, especially compared to areas further north where burned structures are common. There are more burned structures in the Chuskas and near Mount Taylor, on the edges of this region, however, and it is possible that the lack of them in the central basin relates more to the lack of construction wood than to any lack of violence. The authors suggest that, given the known evidence for strife and community abandonment in the Mesa Verde region, one attraction of the Chaco Basin might have been its relative emptiness, which may have drawn people into this much harsher and less fertile region. There’s a general tendency for settlement to cluster around drainages and particularly at  confluences of drainages, likely because these locations offered the best agricultural potential in a very dry area even by Southwestern standards. Regardless of what it was that initially drew people into this area, it’s becoming increasingly clear that this influx of population was a key factor in the later rise of Chaco.

Peñasco Blanco Framing Huerfano Mesa

The authors also discuss visibility and sacred geography, which has been a key concern of Van Dyke’s in her previous work. Many of the prominent community buildings in late Pueblo I sites in this region, whether or not they can be considered “great houses,” are situated in locations where important regional landmarks can easily be seen. This indicates that the concern with visibility associated with later Chacoan great houses likely had its roots in this period.

Finally, the authors summarize community settlement patterns in the region. One interesting pattern they note is that in late Pueblo I communities great houses and great kivas don’t tend to occur together, with great houses being more common in the Chaco Basin and great kivas in the Red Mesa Valley. This suggests that two different community integration systems may have been in place in the region during this time. The great house pattern at more northerly sites is interesting in the context of the “proto-great-houses” apparently present at some Dolores area communities further north, especially McPhee Village, and it’s quite likely that there is a direct connection between the two. Great kivas are also common further south, and while they were present at some Mesa Verde Pueblo I sites they weren’t very common. This suggests that at least some of the Red Mesa Valley late Pueblo I communities were in fact settled by immigrants from the south rather than from the Chaco Basin. Some of the earliest communities showing both features were in Chaco Canyon, and it may well be that one factor in the rise of Chaco was the ability of emerging elites there to combine the two traditions into a new social and ideological system, one that would spread far and wide, remaking the course of Southwestern prehistory.
