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.

Pictographs on Cave Wall behind Room, Gila Cliff Dwellings National Monument

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.

Pictographs at Lower Scorpion Campground

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.

Cliff Dwellings from Trail, Gila Cliff Dwellings National Monument

Over Labor Day Weekend my mom and I went down to southwestern New Mexico to see the Gila Cliff Dwellings.  We had been wanting to go there for a long time, but it’s pretty far from Albuquerque (about a six-hour drive) and not really on the way to anywhere else, so we hadn’t gotten around to it until now.  With me going away to Alaska soon, this was a good opportunity.  We camped at Lower Scorpion Campground, which turned out to be a fortuitously good location since there are some pictographs and a cliff dwelling right in the campground.  The main attraction, of course, was the cliff dwellings themselves, and they were quite spectacular.  They’re not particularly easy to get to.  They are accessible by paved road, unlike Chaco, but it’s a very long winding road through the mountains, so it takes quite a bit of effort.  The sites are definitely worth the effort, though.

Labor Day is apparently the busiest time for visitation there, so it was quite crowded, and there were a lot of volunteers around answering questions and so forth.  Gila Cliff Dwellings is one of the less-visited Park Service units, so it relies almost entirely on volunteers.  At the visitor center they told us that the monument only has two paid employees; I had heard once that they only had one (the superintendent), but I guess they’re up to two.  Part of the reason they can get by like this is that they’re surrounded by the Gila National Forest, so the Forest Service can pick up a lot of the slack and do the things that the monument doesn’t have the staffing for.  The monument itself is tiny, and basically consists only of the cliff dwellings themselves and a Mimbres village, the TJ Ruin, which is apparently not open to the public.  The visitor center and the campgrounds are on Forest Service land, and the visitor center is shared by both the Forest Service and the Park Service.

Gila Visitor Center, Gila Cliff Dwellings National Monument

I hadn’t known very much about the Gila Cliff Dwellings before going there.  I knew that they were built by the Mogollon culture, and that they were the only Mogollon sites managed by the Park Service, but aside from that I didn’t have much of a sense of what to expect.  Luckily, the visitor center has a nice museum and a very informative and up-to-date video explaining a lot of the background.  The cliff dwellings are really quite unusual for Mogollon sites, which were usually either pithouse villages or above-ground pueblos in open areas like the Mimbres villages.  Cliff dwellings are more typical of the Anasazi to the north at places like Mesa Verde, of course, and these were very reminiscent of sites like that architecturally.  They’re quite close to the Mimbres Valley, so I had thought there might be some connection between them and the Mimbres, probably the best-known division of the Mogollon, but apparently the current archaeological thinking is that the cliff dwellings were not built by the Mimbres but by the Tularosa Mogollon, who mostly lived a bit further north but apparently migrated to the south and built the cliff dwellings in the late thirteenth century AD.  This seems to be established by the pottery found at the cliff dwellings, as Tularosa pottery is very distinctive and different from other Mogollon pottery traditions.  I believe it’s more similar to some Anasazi styles, which would fit well with the Anasazi-like architecture.

Gila Cliff Dwellings National Monument was established in 1907, the same year as Chaco, but apparently the sites had already been very significantly pothunted by then, and there was very little left for archaeologists to find once the sites were protected.  Interestingly, one of the volunteers answering questions at the sites when I was there mentioned that the pothunters mostly left behind things like corncobs, so we have a pretty good idea of the subsistence system of the people who occupied the sites even though we don’t know a whole lot about their tools or other aspects of material culture.  I guess there must have been a bit of Tularosa-style pottery left behind and/or in private collections originating from the early pothunting.  Anyway, the upshot of all this is that there has been essentially no professional excavation of the cliff dwellings, and they are rarely mentioned in the archaeological literature as a result, which is really unfortunate because they’re fascinating sites.

Corncobs at Gila Cliff Dwellings National Monument

Like most cliff dwellings, these ones preserved a lot of perishable materials that rarely survive in open sites.  I mentioned the corncobs before, and there are also a lot of wooden beams in situ.  These have been sampled for tree-ring dating, which found that all construction of the sites took place between AD 1270 and 1300, mostly in the 1280s.  The sites were probably only occupied for one generation at most.   This seems like a short period, but it’s actually pretty typical for cliff dwellings.  Many of the much larger sites at Mesa Verde were occupied for almost exactly the same interval.  The late thirteenth century seems to have been the main period for cliff-dwelling construction throughout most of the Southwest.

This is of course the period of the “Great Drought,” and the obviously highly defensible nature of cliff dwellings has led to much speculation that their florescence at this time was due to defensive considerations.  This has been a somewhat controversial proposal further north, and Park Service sites tend to downplay it, but at the Gila sites the interpretive material states outright that defense was probably a major factor in the occupation of the cliff dwellings.  I find this interesting.  It may have to do with the relative distance of the modern Pueblos from this area, and resultingly lower political controversy over discuss of prehistoric warfare, but it may also have to do with the nature of Mogollon archaeology, which developed somewhat differently from Anasazi archaeology.  Steven LeBlanc, who is probably the most prominent archaeologist to argue for a major role for warfare in the prehistoric Southwest, has his particular expertise in the Mimbres area.  This is all just speculation on my part, of course.

T-Shaped Doorway, Gila Cliff Dwellings National Monument

One of the cliff dwellings has a t-shaped door.  This is a type of architectural feature that is common at Chaco (and Mesa Verde) as well as at Casas Grandes to the south.  Many people have argued that this represents some sort of Mesoamerican influence on those sites, and Steve Lekson has argued that it is one of the signs of continuity between Chaco and Casas Grandes.  Its presence here, between the two, and in association with a very Anasazi-like type of architecture deep in Mogollon territory, is certainly intriguing.  Macaw feathers were also found at the cliff dwellings.  The importance of the macaw at Chaco and Casas Grandes (where they were bred on a huge scale), as well as in the Mimbres area, is well known, and of course they would have to have come from further south initially.

Anyway, these are some really fascinating sites that raise the possibility of a lot of intriguing connections to other parts of the Southwest and beyond.  I highly recommend a visit to them for anyone.  Unlike a lot of the sites in the Southwest, these are very impressive even to people without much particular interest in archaeology, on account of their fantastic preservation and stunning location.

"Supernova" Pictograph

Happy Fourth of July, everyone.  The Fourth is actually a pretty important date for the study of Chaco, but in a roundabout (and somewhat controversial) way.  It all has to do with a very famous pictograph panel below Peñasco Blanco at the west end of the canyon.  While the interpretation of this panel is a matter of considerable debate, one way it’s been seen is as a record of an astronomical event that is known to have occurred during the height of Chaco’s power and influence: the supernova of 1054, which formed the Crab Nebula.

We know from several Chinese reports that the “guest star” resulting from the supernova first appeared on July 4, 1054 and continued to be visible day and night for almost two years.  There are a few Japanese records of the supernova as well, along with one report from the Arab world.  No clear-cut and unambiguous accounts are known from Europe or elsewhere in the world, although a few rock art panels in the Southwest have been proposed as representing the event.  The most famous of these is the one at Chaco, which is often referred to as the “Supernova Pictograph” (even by the park itself in a sign at the site).  It consists of three symbols painted onto the rock face in red: a hand, a crescent, and a starburst-like shape.  It’s the starburst that has been interpreted as representing the supernova itself, of course, and the crescent has been seen as representing the crescent moon.  On the morning of July 5, the moon, which was a crescent at the time, would have appeared in roughly the same relationship to the supernova, as seen from the pictograph site, as the relationship between the two symbols on the panel.  Furthermore, the handprint points in the direction one would have looked to see this at at the time.  The combination of the three symbols together, plus the fact that this would have happened at a time of considerable activity in the canyon, has led some to suggest that this pictograph panel was created to commemorate this historic event.  The specific location may have been an established sun-watching position, from which the new star was seen unexpectedly and recorded.

Sign at the "Supernova Pictograph"

It all sounds fairly plausible as it goes, but there are some problems with this theory.  Probably the biggest problem is that the specific set of symbols on the panel is known from ethnographic evidence to have been used by the Zunis to mark generic sunwatching sites, with the crescent representing the moon, the starburst representing the sun, and the hand marking the location as sacred.  Now, it’s certainly possible that these symbols came to be associated with this activity as a result of the observation of the supernova at this site, but as far as I know there’s no reference to the supernova in ethnographic descriptions of astronomical observation at Zuni or any of the other modern Pueblos, so this is a pretty tenuous claim.

Furthermore, while the 1054 supernova would certainly have been noticeable at Chaco, there was an earlier supernova in 1006 (also recorded by the Chinese, and possibly by the Hohokam in southern Arizona) that was much brighter, and it’s not clear why the Chacoans wouldn’t have recorded that one too.  It took place before the Chaco system really got going on a regional scale, but there was plenty of activity in the canyon during the 900s, so people there would presumably have seen it.  It’s possible that it was recorded too, at some other site that hasn’t been found or that has disappeared in the thousand years that have elapsed since the event (note that the existing Supernova Pictograph has only survived because it was under a protective overhang), but again, there’s not any evidence for this.  The Chacoans are definitely known to have kept careful track of regular patterns in the skies, such as the solstices and the lunar standstills, so they surely would have seen unusual events such as supernovae, but it’s not clear how they would have reacted to them or how inclined they would have been to record them.

View Looking East from "Supernova Petroglyph"

So it’s not really clear how to interpret the Chaco pictograph.  I think the balance of evidence at this point leans slightly against it being a representation of the supernova, but I could be talked out of that position if some additional evidence for the supernova theory can be found.

Others, however, have proposed even more extreme theories based on the 1054 supernova.  Among the more noteworthy of these is a proposal by Timothy Pauketat and Thomas Emerson, in a 2008 article in the Cambridge Archaeological Journal, that the rather sudden florescence of the Cahokia site in Illinois around AD 1050 may have had something to do with the supernova.  The theory they present is interesting, but hard to effectively support.  For one thing, dating methods in the Midwest are much less precise than in the Southwest, so pinning down any event to the year is usually not possible.  There is certainly a suggestive correspondence between the sudden rise of Cahokia and the supernova, however, and this is supported by the apparent use of stellar imagery and symbolism at Cahokia and the importance of the stars to later cultures in the area, so there may well be something to this.

Opening at Casa Rinconada That Channels Sunbeam at Sunrise on Summer Solstice

I’m a bit troubled, however, by the reliance of Pauketat and Emerson on evidence from Chaco and the way they interpret it.  For one thing, they say that the Supernova Pictograph is “above” Peñasco Blanco, when it’s actually below it, and not visible from the great house itself.  More importantly, they say of the effect of the supernova:

Some believe that this particular cosmic event, which left behind the Crab Nebula, was commemorated in architecture and iconography at the time or in subsequent years. The most compelling evidence for this comes not from the Cahokia region but from the American Southwest, where a tree-cutting date places the construction of the largest and most isolated ceremonial building in Chaco Canyon, Casa Rinconada (noted for its many astronomical alignments) to AD
1054.

Now, it’s true that there is a single tree-ring cutting date from Casa Rinconada that dates to 1054.  This is, however, the only tree-ring date for the site, so while it’s plausible that it dates the construction of the site this definitely cannot be stated as definitively as Pauketat and Emerson state it here.  There is no specific provenience information available for this beam, so there’s no way to tell how it was used and whether it can plausibly be said to date to the initial construction of the site.  The general architecture of Casa Rinconada is consistent with a construction date in the 1050s, but without more specific information tying it to a specific year on the basis of one unprovenienced beam is unwarranted.

Looking through Solstice-Aligned Opening at Casa Rinconada toward Aligned Niche

Furthermore, even if Rinconada was built in 1054, that doesn’t establish that it was built because of the supernova.  There was extensive construction in the canyon throughout the mid-1000s, associated with Chaco’s apparent rise to regional dominance, and this began well before 1054.  The major expansion of Pueblo Bonito began by the 1040s at the latest, and various other construction projects at other sites in the canyon dates to this general period.  Rinconada could easily have been part of this general process without any specific relationship to the supernova.  Indeed, there’s nothing about Rinconada that seems to refer to the supernova, despite the various astronomical alignments (some of them controversial as well, it should be noted) identified there.

None of this means that the supernova didn’t have an important role at Cahokia, of course, and it doesn’t even rule out an important role at Chaco itself.  It does mean, however, that developments at Chaco shouldn’t really be used as evidence for developments at Cahokia, even though the two sites are contemporaneous and Chaco can be dated much more precisely.  Cahokia may well have risen as a result of the 1054 supernova, but neither the Supernova Petroglyph at Chaco nor the one tree-ring date at Casa Rinconada provides evidence that it did.

Atlatl Petroglyph, Atlatl Rock, Valley of Fire State Park

Jim Weller, who has extensive experience with atlatl construction and use, e-mails with some very interesting thoughts.  About the atlatl petroglyph on Atlatl Rock at Valley of Fire State Park in Nevada, which I have used to illustrate some earlier posts, he says:

What I find very interesting . . . is that the atlatl in that petroglyph doesn’t have a hook.  It’s forked at the end, which I assume means it had a string across the fork and the darts had nocks like an arrow.

. . .

This page here is what made me think the atlatl in the petroglyph was fork-and-string.  The business end of the 2nd atlatl shown looks just like the petroglyph, although it lacks finger loops on the other end. http://www.primitiveways.com/loop_cord_atlatl.html
Also, on finger loops:
As to finger loops, in my own tinkering with atlatls, I’ve developed a preference for them.  This is because the human wrist moves a lot more up-and-down than it does left-to-right, and the more wrist movement you can put into the throw, the faster the dart goes.  Without finger loops, throwing is like chopping with a hatchet (or throwing a javelin without an atlatl), limiting you to the left-right wrist motion. With finger loops OTOH, throwing is much like with a baseball, allowing the full up-down wrist snap towards the end of the throwing motion.

I think there’s enough difference in power (and accuracy) with finger loops for them to have been pretty much standard equipment.  Sure, you don’t absolutely need them, and there are many folks today who don’t use them and still achieve excellent results.  However, if my life depended on an atlatl, I’d definitely use them.  They have physics on their side.  And there seem to be more examples of atlatls from all over the world with some sort of finger loop than there are without.  Leather straps, shell crescents, and holes drilled through wide handles.  Thus, I’m not surprised that the loops are emphasized in art.  I prefer the leather straps because they don’t chafe and pinch my fingers as much as the hard types of loop.

. . .

Note in the petroglyph that the atlatl handle is much narrower at the loops than elsewhere.  This is a pretty necessary design feature for using loops on an atlatl that’s more than about 1/2″ in diameter.  So, if you find just the stick and wonder if it ever had loops, look for this narrow place if the rest of the handle is wider than 1/2″.  If there’s no narrow place, then it almost certainly never had loops.  OTOH, if the whole thing is only 1/2″ wide, then there’s no good way to tell.

The reason you need the narrow place on wide handles is because when using loops, the atlatl goes between the index and middle fingers, which still have to wrap back around on top to hold the dart.  The narrow gap between these fingers and their lack of opposability puts a limit on how big an object will fit between them comfortably.  If the atlatl is more than about 1/2″ wide there, you CAN use it, but each throw hurts the inside of your index finger just below the 1st knuckle, and you have to tense up the whole hand and wrist to get a good grip on the dart, which decreases power and accuracy.  Not fun.  But OTOH, if the whole handle is that narrow, you have to tense up your hand anyway to hold it with your thumb and other fingers below the loops.  So the best design is wide enough at the butt for a relaxed grip for the thumb, pinky, and ring fingers, and narrow above for a relaxed grip with the index and middle fingers.

To see how this works, make a peace sign keeping the thumb, pinky, and ring fingers in a comfortable circle so none of them touch the palm.  That’s a good diameter for the lower part of the handle (or the whole handle if you’re not using loops).  Now, keeping your middle and index fingers as far apart as possible at their 1st knuckles, bend them down and in until their tips touch each other and the tip of the middle finger is touching the end of the ring finger.  Look how much smaller the gap between the index and middle finger knuckles is compared to the gap between the other fingers and the palm.
Also, via the interesting Blackwater Draw blog, I see that John Whittaker of Grinnell College has an extensive annotated bibliography on atlatls available on his website.  From it I see that he disagrees with both Calvin Howard and Bob Perkins about the physics of the atlatl.  I don’t know enough about the thing to judge who’s right.  Gaining that kind of knowledge really requires substantial personal experimentation, and while I could do that, I’m mostly interested in the cultural and historical implications of these technologies rather than the details of their operation.  Still, there’s a ton of literature out there for anyone who is interested, and Whittaker’s bibliography would be a great place to start.

Atlatl Petroglyph at Atlatl Rock, Valley of Fire State Park

I’ve decided to do a series of posts on the issue of prehistoric weaponry and the spread of the bow and arrow through North America.  This is an important topic, and one that has received a considerable amount of attention from archaeologists and others over the past century.  Despite that long history of research, there are still a lot of unresolved questions about this, and it has been a highly contentious issue in some circles.

Petroglyph Panel at Atlatl Rock, Valley of Fire State Park

To frame the issue, and to demonstrate its importance to Chaco specifically and Southwestern archaeology more generally, I’d like to go back to a topic I haven’t discussed much lately: warfare, and in particular Steven LeBlanc’s book on warfare in the prehistoric Southwest.  This is a controversial issue, although most Southwestern archaeologists seem to be coming around to the view that warfare was important even if they don’t see it as central the way LeBlanc does.  Leaving all that aside for now, however, LeBlanc also provides a useful model for the spread of prehistoric weaponry in the Southwest that clearly shows the importance of the bow and arrow.  He uses weaponry type as one of the defining features of the three periods into which he divides Southwestern prehistory from the perspective of warfare.  Each period is marked by the adoption of a new type of weapon, in each case more effective than the last.  The periods don’t quite line up with the probable dates of adoption of the new weapons, however, which suggests that there was more going on than mere technological developments.  This has to be the case, actually, because LeBlanc’s middle period (AD 900 to 1150, which roughly coincides with the Chacoan era) is marked by a noteworthy decrease in evidence for warfare despite coming not long after the introduction of the bow and arrow to the Southwest.

Arrowheads at Chaco Visitor Center Museum

LeBlanc’s early period, which runs from the first settlement of the Southwest up to around AD 900, was marked by endemic warfare among small groups using atlatls.  The atlatl, known by various other names such as “spear-thrower” but in this context usually called by its Nahuatl name, is a tool used to launch spears (often called “atlatl darts”) with greater force and to a greater distance than is possible with the unaided hand.  It is found in every inhabited part of the world starting in very early times, and probably dates far back into the Paleolithic Era, before the spread of modern humans throughout the world.  It was thus presumably known to the earliest inhabitants of both the Americas in general and the Southwest in particular.  Most archaeologists generally think of the atlatl in a hunting context, and it would certainly have been used for hunting.  LeBlanc, however, points out that any weapon used for hunting would also be useful in war, and since he proposes that war was going on constantly during his early period, it stands to reason that the main weapon would have been the atlatl.  He also argues that the large wooden club-like artifacts found in sites of this era, often known as “rabbit sticks” and associated with hunting of small game, were instead “fending sticks” used to deflect atlatl darts.  I’m not sure I buy this, but it does make sense that people fighting with atlatls would want to do something to defend themselves against darts coming at them and the sticks would work.  Support for the idea that the atlatl was a weapon of war in addition to a hunting tool comes from Mesoamerica, where military use of the atlatl came to be a major feature of the very warlike societies there.

"Rush to the Rockies" Sign, Trinidad, Colorado

At some point near the end of LeBlanc’s early period, a new weapon system appeared in the Southwest: the bow and arrow.  The spread of the bow and arrow is fascinating, since unlike almost all other examples of diffusion of ideas and technologies through North America it came not from the south but from the north.  It originated somewhere in Eurasia very early on, and then spread very slowly to the Bering Strait, and from there on down the continent.  The most interesting part, and something that I’ll be addressing in more detail in subsequent posts in this series, is that it’s possible to track the movement of the bow and arrow south from the Arctic by looking at the first appearance of it in rock art and artifact assemblages at sites in various areas.  It reached the Southwest sometime around the Pueblo I period and immediately replaced the atlatl as the preferred weapon for both hunting and (presumably) war.  It then continued to spread to the south, but for some reason it didn’t really catch on in Mesoamerica the way it had in most of the areas to the north.  This may have been because of the cultural importance of the atlatl, but it could also have been because it had just barely reached central Mexico when the Spanish arrived and threw everything into chaos.  In fact, I’m not entirely sure it got as far as central Mexico at all; I haven’t found any sources that discuss this precise issue, although there’s been so much attention paid to Aztec warfare that I’m sure it’s discussed somewhere.  It definitely never reached the Maya.  All these Mesoamerican groups were still using the atlatl as their primary weapon when the Spanish showed up with guns.

LeBlanc’s late period, from AD 1250 until Spanish contact, is associated with the use of the recurved bow, which is a more powerful weapon than the self bow that had been used before and may have had something to do with the immense amount of violence that is evident in the Southwest during this period.  This is an interesting topic in its own right, but I’m not really going to go into it in this series, which is more focused on the initial adoption of the (self) bow and arrow in various parts of North America.

Stairs to Atlatl Petroglyph at Atlatl Rock, Valley of Fire State Park

Okay, so, that seems pretty straightforward, doesn’t it?  If there is clear evidence for the spread of the bow from Asia into North America and then south, where’s the controversy?  Well, I was a bit too glib above in saying that the spread of the bow and arrow can be easily tracked by looking at its first appearance in the archaeological record in various areas.  The general picture still holds, I think, but the details are muddled, and there is considerable disagreement among archaeologists about what counts as evidence for the introduction of the bow and arrow in some regions.  The main reason for this is that in most areas, the actual bows and arrowshafts don’t survive, since they’re made of perishable materials.  Nor, for that matter, do atlatls, at least in their entirety.  The main remains of both types of weapons are the projectile points, which are usually made of hard stone.  Atlatls also can have parts attached to them (known as “spurs” and “weights”) which are made of harder materials like stone or bone, and these can survive even when the wooden body of the atlatl doesn’t, although they can be hard to recognize on their own.  In general, then, dating the replacement of the atlatl by the bow and arrow requires the ability to differentiate between dart points and arrowheads.  Since atlatl darts are spears, it is generally thought that they should have bigger, heavier points than arrows, and size is indeed one criterion used to differentiate between the two types of point.  This is controversial, however, for reasons that I’ll go into in future posts.

Hollow Mountain Gas Station, Hanksville, Utah

The entry of the bow and arrow into the Southwest, by the way, is dated much more precisely than is the case in other reasons, primarily because the much better preservation conditions in many Southwestern contexts mean that actual atlatls, darts, bows, and arrows do often survive, which allows a much better understanding of what they were like than is possible elsewhere.  This has been very helpful in getting a sense of the situation elsewhere, although other factors mean that it can’t answer all the questions about those other places.  This importance of the Southwest to understanding the spread of the bow and arrow, despite not being the area where that spread either began or ended, makes this blog a good place for an examination of the issue, as does the importance of that spread to understanding cultural developments in the Southwest.  Those developments seem to have something to do with changes in weaponry, although the precise connection is difficult to discern.

Pipe Shrine House, Mesa Verde

When I visited Mesa Verde this summer, I noticed a rather odd sandstone block at Pipe Shrine House, one of the mesa-top sites known collectively as the Far View Group.  These sites, like many others in the park, were excavated by Jesse Walter Fewkes in the early twentieth century, and documentation of the work done on them is correspondingly sparse.

Sandstone Block with Spiral Petroglyph at Pipe Shrine House, Mesa Verde

The block in question has a spiral pecked into it.  Not a whole spiral, though; rather, the middle of a spiral, with the upper and lower parts missing, as if the block were cut from a cliff face where a spiral petroglyph had been pecked.  Indeed, the only really plausible way to explain the block is that it was indeed cut from such a cliff face.

Block Incised with Zigzag Lines at Coyote Village, Mesa Verde

This is very odd.  I’ve never seen anything quite like it elsewhere.  There are a few other sites in the Far View Group that have blocks with designs on them, mostly parallel lines, but those are generally incised and they don’t bear much resemblance to common petroglyph designs.  They don’t show any particular evidence of the designs having been present on the stones before they were cut, either.  The spiral, though, is a very common type of petroglyph, and the Pipe Shrine block remains very puzzling.  Who cut that block?  Where?  Why?

It’s very hard to say.  The fact that the block is at the top of the current wall strongly suggests that it was not originally part of the site.  In sites like this the top stones are generally modern capping put on with cement to protect the original walls beneath.  The spiral block, then, was almost certainly put on in the twentieth century.  It may have been put on by Fewkes himself after he excavated the site; recent dendrochronological research at the Sun Temple, which Fewkes also excavated and stabilized, has shown that he did a substantial amount of rebuilding there, and it’s quite plausible that he did the same at Pipe Shrine House.  If it wasn’t Fewkes, it was probably some later Park Service stabilization crew.

Regardless of who put the stone where it is now, though, the bigger question is where they got it, and how.  The mystery is amplified by the fact that Mesa Verde is known for having relatively few petroglyphs compared to many other areas with comparable ancient populations.  The stone looks like the same Cliff House Sandstone (Mesa Verde Formation) as the other stones in the wall, although its patina seems to be a slightly different color, which may or may not be relevant to its origin.  There’s no reason to think it comes from anywhere other than Mesa Verde, but that makes it all the more inexplicable that Fewkes or anyone else would have cut into one of the few petroglyph panels on the mesa for building stone when there are few things in the area more plentiful than sandstone.  I’m no expert on Mesa Verde, of course, so it’s quite possible that the story of this stone is well-known or at least published somewhere in the voluminous literature on the archaeology of the area, but if so I haven’t seen any reference to it.  It’s just very puzzling, and I don’t have a clue what the answer is.

Little Colorado River from Homol'ovi Ruins State Park

Some of the most important work on the origins of the kachina cult is that done by E. Charles Adams of the Arizona State Museum, particularly his 1991 book focusing specifically on the subject. In this book he summarizes the available evidence for the origin and early development of the kachina cult, and based on the distribution of the archaeological manifestations of the cult that he identifies he concludes that it originated in the Upper Little Colorado River area of east-central Arizona in the period between AD 1275 and 1325.

Adams’s reasoning for this conclusion is based on his comparison of the distribution of four types of evidence that he presents as reflecting the presence of the cult: rock art, pottery, plaza-oriented village layout, and rectangular kivas. His summaries of the distribution of all these features in space and time are very useful, but his conclusions about the origins of the kachina cult go well beyond the evidence he presents and are not very convincing. His method for determining the origin of the cult is to look at the distribution of the four features he identifies and find where they first overlap. This seems reasonable enough.

Unfortunately, there does not turn out to be any place where the features all overlap sufficiently early to be associated with the initial development of the cult, so Adams has to resort to finding a place where three of the elements overlap. The three elements he uses are pottery style, plaza-facing village layout, and rectangular kivas, which he finds present together earliest in the Upper Little Colorado River area in the late thirteenth and early fourteenth century. He therefore concludes that this is when and where the cult originated and proceeds to describe its rapid spread to the north and east over the course of the fourteenth century. Unlike many other researchers, including Polly Schaafsma, he considers the cult to be fundamentally indigenous rather than Mesoamerican in origin, although he concedes that some elements of it were probably subject to influence from groups to the south such as the Hohokam and Salado.

Adams theorizes that after its initial spread the cult was greatly elaborated at Hopi, where it acquired its strong association with rainmaking and began to be reflected in elaborate kiva murals, and that it subsequently spread in modified form from Hopi to areas that had already adopted the initial cult directly from the Upper Little Colorado, such as Zuni and the Albuquerque area of the Rio Grande valley. It is only at that point, after AD 1400, that Adams sees any influence from the Jornada Mogollon coming up the Rio Grande, and he sees this influence, reflected in the Jornada rock art style and a similar style in some kiva murals, as secondary to the Upper Little Colorado and Hopi kachina cult influence already present in the Rio Grande valley. He even speculates that the Jornada influence may not have affected the kachina cult itself at all, and that it may have had more to do with other societies present among the Eastern Pueblos having more to do with war.

This theory is problematic for a number of reasons. For one thing, Adams relies very heavily on the distribution of pottery styles as evidence for the spread of the kachina cult, but he never establishes the association between the cult and the styles he mentions. He focuses on the so-called “Fourmile style” (named after Fourmile Ruin in the Upper Little Colorado area), a style of polychrome decoration that affected pottery types throughout the Southwest in the fourteenth century. Among the features of Fourmile style that Adams emphasizes are its use of asymmetrical decoration on the interiors of bowls, its extensive use of bird and feather imagery, and its occasional use of obvious kachina cult symbolism, particularly masks or whole anthropomorphic masked figures. It is the last aspect of the style that is clearly most associated with the kachina cult, and the presence of this sort of imagery on ceramics is certainly as clear a sign of the presence of the cult in a given area as the presence of similar motifs in rock art, but Adams goes beyond this observation to associate any use of the Fourmile style with the spread of the cult. This is not something that can just be assumed, however. It is important to note that the Fourmile style was very widespread, including in areas without any other evidence of kachina cult imagery, and it is quite possible that the distribution of the style is completely independent of the distribution of the cult. That is, the Fourmile style may just have been the style of decoration that was popular at the time that the kachina cult happened to be spreading throughout the northern Southwest, so that groups that adopted the cult may have used its imagery on their Fourmile-style ceramics without there being any particular association between the style in general and the cult. Thus, while Fourmile ceramics with kachina imagery would clearly be evidence of the distribution and spread of the cult, Fourmile ceramics without it would not necessarily be, and Adams’s extensive use of them undermines his conclusions significantly.

Another major problem with Adams’s approach is the way he largely disregards the rock art evidence. When he realizes that there is no place where all four of his lines of evidence come together at the proper time, it is the rock art evidence that he ignores. This is why he is able to conclude that the cult originated in the Upper Little Colorado area, where rock art evidence for the presence of the cult is very slim (probably due largely to the limited study of rock art in this area). Rock art, however, is the most straightforward and obvious evidence there is for the presence of the cult. Unlike Fourmile style ceramics, Rio Grande style rock art is full of kachina imagery, and it is very different from earlier rock art styles in the area where it appears. Schaafsma’s theory linking the cult to the Jornada Mogollon depended largely on the rock art evidence. Recall that her argument for transmission of the cult up the Rio Grande via the Jornada depended largely on the lack of rock art evidence for the presence of the cult in the Mogollon Rim and Upper Little Colorado area. Adams, although he argues for the transmission (and, indeed, the origin) of the cult in this area merely assumes that the Rio Grande style originated in the Upper Little Colorado area along with the cult and that it is unrelated to the Jornada style, which he sees as a late introduction to the Eastern Pueblos after the Rio Grande style was firmly established.

It is not hard to see why Adams puts so much emphasis on pottery and so little on rock art. He is trying to determine the time as well as the place of origin of the kachina cult, and to do that he needs evidence that can be securely dated. In the Southwest pottery styles are very well dated by association with tree-ring-dated contexts where they appear, and they therefore give quite precise dates even for sites that have note been excavated or dated in any other way. Rock art, on the other hand, is notoriously difficult to date. Pictographs, which are painted onto the rock surface often using some sort of organic paint, can sometimes be carbon-dated by samples of the paint or other associated organic artifacts, but this technique has rarely been used in the Southwest, and the much more common petroglyphs, which are pecked or incised into the rock surface, cannot be directly dated at all and can only be assigned very general dates based on their style and/or proximity to dated sites. Thus, associating the spread of the kachina cult with the spread of the Fourmile style, which does seem to have occurred around the same time, gives Adams much more chronological control than Schaafsma has with her rock art styles, and it even allows him to argue, in direct opposition to Schaafsma’s interpretation, that the Jornada style in the Rio Grande valley is later than the Rio Grande style rather than ancestral to it. His justification for doing so is very shaky, being based on similarities between the Jornada style and the style of kiva mural found at sites such as Kuaua, north of Albuquerque, but it is not possible to prove that he is wrong. Nor, for that matter, is it possible to prove that he is wrong to associate the Fourmile ceramic style with the cult, although he does so on similarly shaky grounds.

Nevertheless, despite all these problems with Adams’s theory for the origin and spread of the cult, his model for why the cult was adopted so quickly and easily throughout the Pueblo world is quite convincing and useful. The explanation is basically the same as Schaafsma’s: the kachina cult, being a non-kin-based system with the potential to integrate whole communities easily, was very attractive to the rapidly aggregating villages developing throughout the Southwest at this time, and it was therefore adopted as a way of dealing with and resolving the many conflicts that inevitably develop within diverse and rapidly growing communities. He defines the model more rigorously and in more detail than Schaafsma, however, and presents a four-stage process for adoption of the cult, with corresponding correlates that should be identifiable in the archaeological record:

  1. Immigration: Starting around AD 1275, when major environmental changes occurred throughout the Southwest, locations that either maintained their attractiveness for settlement or became newly attractive as a result of the changes saw massive influxes of population from the many areas being abandoned at this time.
  2. Aggregation: In the locations seeing large-scale immigration, the new immigrants coalesced into large, aggregated villages, either joining previously existing populations or, in sparsely populated or previously unattractive locations, developing their own aggregated villages. These villages are often but not always plaza-oriented.
  3. Appearance of kachina cult imagery: Shortly after initial aggregation, the plaza-oriented villages begin to show signs of kachina cult imagery, either in nearby rock art or on locally produced pottery. This demonstrates the adoption of the cult by the village, perhaps in part to deal with the problems caused by rapid aggregation.
  4. Continued aggregation: As a result of the usefulness of the kachina cult in integrating the new communities, new immigrants continue to join them and are able to be successfully integrated. This part is important; previous attempts at forming large, aggregated communities in the Southwest had not lasted for long, probably because existing religious and social systems were not able to successfully integrate populations on that scale.

Adams applies this model to the cluster of sites at Homol’ovi Ruins State Park near Winslow, Arizona, where he has conducted extensive research as part of a long-term project by the Arizona State Museum. He finds that the model fits the history of the sites there quite well. Adams’s model can also be used to evaluate the impact of the kachina cult and the development of plaza-oriented village layouts on aggregation in other parts of the Southwest during this time period, and perhaps during others. Adams sets the beginning for his model at AD 1275 to correspond to the environmental changes in the northern Southwest associated with the so-called “Great Drought” of AD 1276 to 1299, and this does correspond to the onset of major aggregation in many areas, but in other areas aggregation began either earlier or later than this, and the adoption (or, perhaps, development) of the kachina cult may have played a role in these contexts as well.

Adams’s model may be an effective way to address the relationship between aggregation and the spread of the kachina cult, but it still leaves open the question of why people were aggregating in the first place. This has been a matter of much dispute and argument over nearly the whole history of southwestern archaeology, and many theories have been proposed. Many of the recent theories revolve around changing environmental conditions and the need for changes in subsistence systems, and they address this idea from varying perspectives, often focusing on the need for more centralized decision-making and/or more efficient land use as the result of less reliable or more difficult conditions for agriculture. In his discussion of this issue, particularly in relation to the case study of Homol’ovi, Adams seems to endorse some version of this idea, with a particular focus on the decisions of community leaders. Unlike many archaeologists who study the ancient Southwest, Adams does not present prehistoric Pueblo society as egalitarian, and he assumes throughout his discussion the presence of a two-tiered society with a small priestly class making decisions at a community level and deriving their authority from their control of ritual knowledge. Importantly, however, he notes that this elite never managed to amass the sort of surplus wealth necessary to transform Pueblo society into a truly stratified society with significant economic inequality. Adams attributes this mainly to the marginal nature of the Southwest for agriculture, but it is likely that another major factor is the communal ideology of the Pueblos, which strongly discourages individual gain and encourages leaders to put the needs of the community above their own desires.
