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.


Animas River, Durango, Colorado

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.

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.

McPhee Reservoir and Mesa Verde Escarpment from McPhee Campground

McPhee Reservoir and Mesa Verde Escarpment

The second chapter of Crucible of Pueblos discusses the Central Mesa Verde region, which is defined as basically the southwestern corner of Colorado, bounded on the west and south by the modern borders with Utah and New Mexico, on the east by the La Plata River valley, and on the north by the highlands north of the Dolores River. This is the region where Pueblo I period villages have been most extensively studied, primarily by the Dolores Project during the construction of McPhee Reservoir in the 1980s and in subsequent research by archaeologists building on that work. As a result, there’s not a whole lot that’s new in this chapter for someone who has been following the literature on this topic, although it does make a good introduction to the subject for someone who hasn’t. It also discusses some parts of the area, especially the northern and eastern fringes, that have seen much less research than the well-studied Great Sage Plain (including the Dolores sites) and Mesa Verde proper. Overall, the data assembled here is among the most detailed and reliable available to analyze demographic trends and population movements during the Pueblo I period in the northern Southwest.

Among the key factors that the authors discuss are the inherent attractiveness of this region to early farmers because of its good soil and relatively favorable climatic conditions compared to other nearby areas. Indeed, this is the only part of the northern Southwest that has seen extensive dry farming in modern times, and it is still primarily agricultural in use. This makes it unsurprising that early farmers would have concentrated here, as indeed they did, starting in the Basketmaker III period ca. AD 600 and increasing steadily in population through about 725. These early sites generally consisted of scattered hamlets presumably housing individual families. Villages, which in this context means clusters of multiple residential roomblocks in close proximity, began to appear around 750, often in association with great kivas, which had previously been rare in this region for reasons that are unclear.

Villages to both the west and east, discussed in subsequent chapters, date to the same period as these early ones in the Central Mesa Verde villages, and there was a striking variety in community organization and layout across the broader region. The dissolution of the eastern and western villages seems to have contributed to an influx of population into the Central Mesa Verde area in the early ninth century, resulting in the largest and densest concentration of population seen to that date. Village layout also became more standardized, with two main patterns dominating, one associated with great kivas and another including U-shaped roomblocks that were likely ancestral to later “great houses.” These villages, most extensively documented at Dolores, were however short-lived, and by the early tenth century the area was almost completely depopulated, with the former inhabitants apparently moving primarily to the south, into the southern part of the San Juan Basin, where they seem to have played a key role in the developments that led to the rise of Chaco Canyon as a major regional center in the eleventh century.

As I said before, none of this is groundbreaking information at this point, and I’ve discussed some of the implications of the Dolores data before. It is however useful to have a synthesis of this region during this important period to refer to, and this chapter works well for that purpose.

McPhee Reservoir, Dolores, Colorado

McPhee Reservoir, Dolores, Colorado

A few years ago I did a series of posts called “Aftermath” that consisted of short commentaries on the chapters in The Prehistoric Pueblo World, a volume edited by Michael Adler that synthesized information on the archaeology of the Pueblo III period (AD 1150 to 1350) in various regions of the Southwest. This period postdated the decline of Chaco Canyon as a major regional center, and understanding it is important for understanding the relationship between Chaco and the modern Pueblos, as well as for understanding some aspects of Chaco itself.

Another period that is of perhaps even greater interest for understanding Chaco is the Pueblo I period (generally defined as AD 750 to 900, but see below), which immediately predates Chaco’s rise to regional dominance. I was therefore pleased to see the publication in 2o12 of Crucible of Pueblos: The Early Pueblo Period in the Northern Southwest, a volume synthesizing information on the Pueblo I period along the same lines as Adler’s effort for Pueblo III. It’s edited by Rich Wilshusen, Gregson Schachner, and James Allison, all of whom have made important recent contributions to understanding of this under-researched period. I’m just now getting around to reading it, and I decided to do a similar series of posts commenting on the chapters as I read them. I’m entitling the series “Foreshadow” to indicate the way developments during this period seem to, well, foreshadow later developments at and involving Chaco.

This post addresses the introduction, which is by the three editors of the volume along with Kellam Throgmorton, who is not otherwise a familiar name (at least to me) but who is thanked in the acknowledgments for his work “reimagining” this chapter. He was apparently a graduate student at the University of Colorado at the time, and has since graduated and is now “doing contract archaeology work in New Mexico.” The introduction as it stands is very engaging and readable, so if that was Throgmorton’s doing I can see why the volume editors took care to thank him specifically.

This introductory chapter is primarily a history of archaeological research on the Pueblo I period in the Southwest, but it also situates that history in the context of archaeological understanding of that period and how it relates to others, which has changed markedly over time. It also explains the reasoning for this volume’s use of “Early Pueblo” rather than “Pueblo I” to describe the period of interest, which is defined more broadly than Pueblo I has traditionally been. As with so much else in Southwestern archaeology, the issues here go back to the classification developed at the first Pecos Conference in 1927. As this chapter makes clear, this was initially primarily a developmental sequence rather than a chronological one, and the Pueblo I period in particular has been misunderstood on this account. This volume therefore uses a more general “Early Pueblo” period of circa AD 650 to 950 to frame the developments in the regions it discusses, which covers the various definitions that have been used for Pueblo I in different areas, as well as parts of Basketmaker III in some because of the importance of immediately preceding events for understanding Pueblo I.

The bulk of this chapter relates the history of understanding of the Pueblo I period by archaeologists. This history follows the familiar sequence of culture history/classification followed by processualism/environmental determinism followed by post-processualism/neohistoricism, but with an emphasis on how the Pueblo I period tended to be subsumed by larger theoretical constructs until the rise of large cultural resource management projects in the 1970s and 1980s massively increased the data available and forced a reevaluation of the period. The most influential of these efforts was the Dolores Project, which happened to occur in an area that was one of the most important centers of Pueblo I village development. The massive scale of this project, the largest ever in the US at the time, led to a much more detailed understanding of the Pueblo I period and the recognition that, rather than a brief interlude in the sequence of development from small hamlets to large pueblos, this was a time of rapid formation of the first major agricultural villages in the northern Southwest, followed by their equally rapid dissolution and a massive outmigration of people from the region. The precision of tree-ring dating allowed for very fine-grained understanding of the chronology, and the results of the project showed a level of dynamism in population movement and culture change that was totally unexpected and hard to fit in the gradual progression paradigm underlying the traditional Pecos classification.

Furthermore, certain aspects of the short-lived Dolores villages were strikingly reminiscent of the well-known Chacoan communities that emerged to the south shortly afterward, which led to the increasingly accepted idea that the formation and dissolution of villages during Pueblo I in the Dolores area were events that directly influenced the rise of Chaco. Indeed, it is now considered quite likely that many of the people who were involved in the development of early great houses at Chaco had moved there from Dolores.

So that’s the main message in this chapter, which also serves as an introduction to the volume itself and the other chapters in it. The next few chapters cover the specifics of settlement patterns in several parts of the northern Southwest, including not just the Mesa Verde region (the focus of most Pueblo I research so far) but also Chaco and its surroundings as well as areas further south and east. The latter two areas are often not addressed very well in research on this period, so I’m very interested in seeing the information on them presented here. The next few chapters cover a few broad thematic issues of interest for understanding this period across all the regions, then there are concluding chapters by Steve Lekson and John Kantner putting all this in a larger perspective. Overall this seems like a well-designed and desperately needed synthesis of an important but poorly understood period in Southwestern prehistory, and I’m eager to dive into the details.

Looking South from Kin Ya'a

One of the most notable examples of an assemblage of highly mutilated human remains from the Southwest being attributed to witchcraft execution rather than cannibalism, in accordance with J. Andrew Darling’s theory discussed in the previous post, is Ram Mesa, southwest of Chaco Canyon near Gallup, NM.  This site was excavated by the University of New Mexico as a salvage project, and the relevant assemblage was reported by Marsha Ogilvie and Charles Hilton in 2000.

The Ram Mesa assemblage, consisting of 13 individuals, is pretty similar to many other assemblages in the Southwest attributed to cannibalism, but Ogilvie and Hilton make a plausible case that while the remains are clearly highly “processed” there isn’t a whole lot tying this dismemberment and mutilation to actual consumption of the remains.  Few of the bones showed any evidence of burning, a condition which applies to several other cases of alleged cannibalism as well.  The few cut marks, which were mostly found on children’s skulls and lower jaws, weren’t particularly indicative of the removal of large muscles that might be expected if consumption were the object.  On the other hand, however, relatively few of the bone fragments were sufficiently large to be identified to body part, and any diagnostic evidence from these tiny fragments was clearly destroyed by the thoroughness of the processing.  It’s not clear, therefore, how representative the larger fragments with surviving evidence of burning and cutting are of the entire assemblage.  The most I would say about this site is that the evidence is not sufficient to make a positive diagnosis of cannibalism, and other explanations are therefore plausible.

However, as I noted before in discussing Darling’s arguments, witchcraft execution and cannibalism are not necessarily mutually exclusive.  Indeed, the execution of suspected witches may well have involved some level of cannibalism among some Southwestern groups in prehistoric times, thought there is certainly no evidence that it did in historic times as documented by ethnographers.  There are some other oddities about the Ram Mesa site that suggest that it might not be expected to pattern with the majority of the suspected cannibalism assemblages, so it is certainly possible that it represents a variation on the same behavior that may not have included cannibalism.

For one thing, this is an odd place for one of these assemblages.  Although some early excavations at Chaco Canyon and in northern Arizona have been proposed as showing evidence of cannibalism, the vast majority of the well-documented cases are in southwestern Colorado, especially around the modern town of Cortez.  This includes the Cowboy Wash site, the site with the best evidence for cannibalism of any of them.  Given the known cultural differences between prehistoric populations at the northern and southern edges of the San Juan Basin (the San Juan and Cibola Anasazi, respectively), it’s quite possible that the cultural activities resulting in similar assemblages in these two areas may have been somewhat different, with the San Juan groups practicing cannibalism and the Cibola groups not.

Furthermore, there may be differences in the dating of the sites.  Most of the well-documented Cortez-area sites date to right around AD 1150, and they may all represent part of a single event at that time, which was in the midst of a severe drought when social structures were likely under extreme stress.  The Ram Mesa site is dated by six radiocarbon dates to a period that Ogilvie and Hilton describe as “AD 978 to 1161.”  They do clarify that these are calibrated dates, which is helpful, but it would have been better if they had shown the ranges for the individual dates, as well as the materials that were dated, which would give a better idea of the most likely dating for the human remains.  On the assumption that the remains date to the latest period of occupation, which seems plausible based on comparison to similar assemblages elsewhere, this puts the latest date at 1161, which is interestingly close to the dates for the similar Cortez sites.  Due to the lack of information of the dates, however, it’s not clear is this is an intercept (i.e., most likely) date or the late end of a range; if the latter, it’s possible that the assemblage dates to somewhat earlier than the Cortez sites.  In that case it would not be part of the same phenomenon, whatever that was, and the postulated lack of cannibalism may be related to that.

In any case, this site definitely seems to have been within the Chacoan sphere of influence, which makes the interpretation of the remains there important for understanding the relationship of alleged cannibalistic events to the rise and fall of Chaco.  Christy Turner has famously argued that they represent the expansion of the Chacoan system and the use of brutal force by the rulers of Chaco (hypothesized on very dubious evidence to be Toltec immigrants from central Mexico) to ensure that outlying communities were incorporated into the system and supplied tribute to the canyon.  This idea is pretty implausible based on the evidence from the Cortez area, where most of the assemblages date to the period of Chaco’s decline rather than its rise.  If Ram Mesa dates to the same period it would support that evidence, whereas if it dates to earlier it could conceivably either support Turner’s ideas or point to a different interpretation, perhaps having something to do with the well-known fact that the outlying Chacoan communities to the south of Chaco seem to have been abandoned beginning much earlier than those in other directions.  There are a lot of outlying Chacoan great houses in this area, including Casamero and Kin Ya’a, but they seem to have rather different histories than those to the north, such as Aztec Ruins and Yellow Jacket.

Like most research related to Chaco, this paper ultimately raises more questions than it answers.  That’s not necessarily a bad thing, however, especially when it comes to a topic as controversial and poorly understood as these assemblages suggesting cannibalism.

Chaco Preservation Crew Repairing Masonry at the Fort Site

Today’s Albuquerque Journal has an article, originally published in the Gallup Independent, about the Chaco preservation crew and their work maintaining the various sites in the park.  The article focuses specifically on recent work they’ve done at Pueblo Pintado.  I don’t have a whole lot to add, but it’s an interesting account that addresses some of the complications of doing this sort of work for traditional Navajos, who have a strong taboo against even visiting Anasazi sites.  The article says that the crew deals with this in part by conducting prophylactic ceremonies before starting work on the sites, which I hadn’t known.  These ceremonies are apparently led by Harold Suina, a member of the crew who is from Cochiti Pueblo and is not Navajo (although I believe his wife is, and they live near Chaco in an area inhabited almost entirely by Navajos).  The article doesn’t say this, but I suspect that Harold’s role is particularly important since Pueblos like Cochiti have different attitudes toward the sites at Chaco than Navajos do, so he may not feel as uncomfortable dealing with them as the other members of the crew, all of whom are Navajo, do.  Not all of the Navajo members of the crew are traditional, however; some are Christian, as are many Navajos in the Chaco area, and they may not have the same qualms about their work that their more traditional colleagues have.

Anyway, it’s an interesting article, and it’s nice to see the preservation crew getting some media attention.  They do crucial work for the park, but it rarely gets noticed by either visitors or the many people who have written books and articles about Chaco over the years.  When I was doing tours I would usually do a fairly detailed description of the preservation work early on in the tour, both because people often want to know how much of what they see at the sites is reconstructed (at Chaco, very little, unlike at many other parks) and because I wanted them to appreciate how much work it is to maintain the sites and why it is therefore important for them as visitors to treat them respectfully and minimize the amount of damage they cause.  Hopefully this article will serve a similar function for a wider audience.

Core Samples Taken for Tree-Ring Dating, Gila Cliff Dwellings National Monument

Despite their impressive preservation, the Gila Cliff Dwellings have gotten surprisingly little attention in the archaeological literature.  This is apparently because they were so thoroughly ransacked by pothunters early on that there wasn’t much left intact for archaeologists to study, and possibly also because the early establishment of Gila Cliff Dwellings National Monument in 1907 has led most subsequent research to be done by the National Park Service, which has often had a tendency to keep findings in internal reports for management purposes rather than publishing them in peer-reviewed journals or books.  The surviving structural timbers have clearly been sampled for tree-ring dating, and the interpretive material put out by the monument discusses the results of this analysis.  The museum at the visitor center also displays some artifact that were apparently found in the cliff dwellings, although it’s not always clear if they were excavated by the NPS or recovered from private collections after having been looted and sold.  The NPS does have an online administrative history of the monument; I haven’t read it yet, but from a casual look through the section on archaeological research it seems to confirm that there has been some excavation by the Park Service, mostly in the 1960s, but that the data have not been thoroughly analyzed or reported.

The only substantial discussion of the cliff dwellings that I have found in the published literature is a short article published by Editha Watson in 1929.  She discusses several cave sites in the Upper Gila River area, but gives the most detailed description (which is still not very detailed) of the caves in the monument.  She discusses the highly looted state of the sites and some of the things found in them, although she does not make it very clear who found them or how:

Corncobs are plentiful in this ruin. They are very small, and the dry atmosphere has preserved them so beautifully that they may be indented with the fingernail. Black-and-white pottery and corrugated ware blackened on the inside are the only sorts noticed among the sherds. Turquoise beads have been found here. As this is a national monument, excavation is forbidden, but vandals have torn up the floor in search of treasure.

She also mentions a “desiccated body of an infant” found in one of the caves.  According to the administrative history four such mummies were allegedly found in the cliff dwellings at various points in the late nineteenth century and sent to the Smithsonian, which apparently never received any of them.  It’s not clear which of these Watson refers to, or where she got her information.

Watson also mentions the red pictographs found in the caves, which she says are “supposed to be the work of later tribes.”  As the administrative history notes, it’s not clear who is supposing this or why.  More recently, Polly Schaafsma has classified these pictographs as belonging to the Mogollon Red style, which is also found to the northwest in the area around Reserve, New Mexico.  She also thinks the pictographs in the caves were made by residents of the cliff dwellings standing on rooftops, which makes sense given their positions and firmly dates them to the late thirteenth century AD.  There are other pictograph locations in and around the monument, including one in Lower Scorpion Campground that is quite impressive in its number and variety of designs.

The Mogollon Red style is very different from most other Southwestern rock art styles, at least the ones I’ve seen examples of.  It includes a lot of abstract geometrical designs and stick-figure humans, and is always in the form of pictographs rather than petroglyphs.  It is particularly different from the Jornada style found to the east in the Mimbres and Jornada Mogollon regions, which consists mainly of petroglyphs and has a lot of naturalistic animals and human faces or masks.  Schaafsma has proposed that the Jornada style represents an ideological system that later developed into the kachina cult of the modern Pueblos.  The Mogollon Red style forms another link between the Gila Cliff Dwellings and areas to the north and west, reinforcing the impression from pottery styles that link them to the Tularosa area.  This is interesting given their geographical proximity to the Mimbres area, with its very different iconographic traditions, and strongly supports the idea that the builders of the cliff dwellings were immigrants from somewhere to the north.

That’s about all I’ve found in the published literature about the cliff dwellings.  Clearly they have a lot of potential to shed light on a number of issues important in the study of Southwestern prehistory, especially interregional relationships and migration, but so far they have not been widely incorporated into discussion of those issues.
