Understanding Abandonments in the North American Southwest

The North American Southwest is renowned for its rich archaeological record. Thousands of prehistoric houses and ceremonial centers remain partially standing or form mounds that mark prehistoric villages that were once actively occupied and remain important to the descendants. The visibility of archaeological remains has sparked interest in questions of abandonment among archaeologists and the lay public. We explore reasons for this interest, how it is manifest in archaeological research, and how perception of that research influences popular views of the past and of native people. Our focus is on explanations for the causes of site and regional abandonment as well as on explications of the processes by which abandonments occur. Essential to our perspective is the view that abandonment is a process that involves decisions to move, which may be promoted by dire circumstances, but which are most often settlement strategies. The process of moving requires economic, social, and political decisions about the places from which people move and to which they move.     

The Hohokam of the American Southwest

The Hohokam, the prehistoric farmers of the southern Arizona desert, have been the subject of increased archaeological investigation in the last two decades. This research is altering traditional views of the Hohokam. New data provide a stronger basis for discussing Hohokam origins and culture history. Although best known as irrigation farmers, the Hohokam had a complex subsistence base that relied on hunting, gathering, and a variety of farming techniques. Studies of site structure and settlement patterning reveal a degree of social complexity greater than previously recognized. The Hohokam were tied to surrounding groups through evolving exchange and interaction networks.     

The history of method and theory in the study of prehistoric puebloan pottery style in the American Southwest

The history of Americanist archaeology can be profitably approached through an examination of ceramic design studies in the puebloan region of the American Southwest. An intellectual tradition is represented throughout these studies, grounded in the assumption that ceramic design variation can be reflected, among other things, in prehistoric social groupings. Within this tradition, a number of differences in method, theory, and application can be distinguished, including (1) the classificatory systems employed, (2) the spatial and temporal scales at which ceramic design variation was studied, and (3) the potential functional role of stylistic attributes on pottery. The debates, both intellectual and social, surrounding the development of method and theory in the New Archaeology are clarified by this historical review, as are the transitions to Culture History and from the New Archaeology in the American Southwest.     

Craft economies in the north American Southwest

Debates concerning sociopolitical organization in the North American Southwest are clarified and confounded by the conclusion that craft specialization was not always a sufficient condition of complexity in the region. Understanding the relationship between varying dimensions of craft specialization (e.g., context, scale, and intensity) and sociopolitical organization in the region requires us to examine a variety of social institutions (e.g., leadership, gender, and ethnicity) that potentially generated differentiated economies. New research on middle-range societies in the North American Southwest and elsewhere in the world should focus on identifying and interpreting the archaeological signatures of specific social institutions and their linkages to craft economies.     

The prehistoric drug trade: widespread consumption of cacao in Ancestral Pueblo and Hohokam communities in the American Southwest

We propose the existence of extensive trade and interaction among the peoples of the American Southwest and Mesoamerica. We base this inference on our detection of the widespread presence of theobromine, the biomarker for cacao, in 50 of 75 vessels used by Ancestral Puebloans (previously referred to as Anasazi) elites and non-elites from the Four Corners area and Hohokam elites of the Gila and Salt river valleys in the prehistoric American Southwest. We used a non-invasive, non-destructive aqueous sampling procedure that provides conservation advantages over the current methods that require crushing and boiling sherds or removing residues from vessel surfaces. Analysis of these samples by sensitive LC-MS instrumentation capable of detecting nanogram quantities of material revealed theobromine in non-local vessel forms found in elite burials in great house and platform mound sites as well as in local vessel forms used by non-elites living in small unit-pueblos. After elimination of plants native to the Southwest as the source of theobromine, we conclude that either Theobroma cacao or Theobroma Bicolor was imported from its homeland in the Mesoamerican tropical coastal lowlands. Our results are at odds with the current consensus that there was little systematic commerce between Mesoamerican and Southwestern polities. We suggest that cacao was exchanged for high quality turquoise such as that mined in the Cerrillos, New Mexico mining district. We conclude that, far from being isolated developmentally, this trade integrally tied populations in the American Southwest to the socio-political and economic activities of Mesoamerican states.     

The archaic prehistory of the North American Southwest

Evidence today suggests that by at least 8000 to 8500 B.P., Archaic hunter-gatherer economies were established throughout the North American Southwest. The Early Archaic seems to be a period of considerable variability across the subregions; this may be a product of currently slim knowledge of the period, or it may indicate that the region witnessed considerable flux. With the Middle Archaic period from 5500 to 3500 B.P. there seems to be greater similarity in material culture across the region and a definite increase in the number of known sites. Finally, the Late Archaic/Early Agricultural period from 3500 to 2000 or 1500 B.P. sees the establishment of a mixed farming-foraging economy in much of the Southwest with apparently major changes in subsistence-settlement systems. Preagricultural Archaic land use patterns are known in broad outline but not in detail; high mobility by small social groups in an annual round would have permitted exploitation of diverse biotic communities. In most parts of the region, significant socioeconomic change accompanies the incorporation of agriculture into the late preceramic period, as witnessed by the appearance of longer-term residential sites with pitstructures and storage features.     

Early agriculture and sedentism in the American Southwest: Evidence and interpretations

Recent archaeological research in the American Southwest is rapidly altering long-held perspectives on early agricultural adaptations. The adoption of maize and squash is now reliably dated to ca. 1200 B.C., rather than 4000–2000 B.C. as previously thought, and new sites have been found in a variety of unexpected ecological settings. These emerging spatiotemporal patterns suggest that the development of sedentary communities after A.D. 500 may have been the result of changing systems of foraging, instead of simply a greater dependence on agricultural production.     

Ancestral pueblo population aggregation and abandonment in the North American Southwest

After over a century of archaeological research in the American Southwest, questions focusing on population aggregation and abandonment continue to preoccupy much of Pueblo archaeology. This article presents a historical overview of the present range of explanatory approaches to these two processes, with a primary focus on population aggregation in those regions occupied by historic and prehistoric Pueblo peoples. We stress the necessarily complementary nature of most of these explanations of residential abandonment and aggregation. Case studies from the northern Southwest illustrate the continuous nature of these processes across time and space. We suggest that additional explanatory potential will be gained by the use of well-defined theoretical units to frame our current approaches. We extend the use of the local community concept as a theoretical unit of organization that, along with explicit archaeological correlates, should help advance our research into population aggregation and abandonment in this and other regions of the world.     

Perimortem mutilation of human remains in an early village in the American Southwest: A case for ethnic violence

Recent excavations at the Sacred Ridge Site, just south of the town of Durango, Colorado, have uncovered the single largest deposit (to date) of mutilated and processed human remains in the American Southwest. This deposit dates to the very late eighth or very early ninth century A.D. and therefore represents an incidence of large-scale violence and perimortem mutilation dating to the Pueblo I period (A.D. 700–900), when initial village formation occurred in the northern San Juan Region of the Southwest. Expectations for various interpretations for the Sacred Ridge assemblage are generated based on previous research and cross-cultural data on cannibalism, warfare, and human bone processing. Based on a lack of fit with previous models developed to account for extreme processing (EP) events, including starvation cannibalism, warfare and social intimidation, and witch-craft accusations, it is proposed that the Sacred Ridge massacre was the result of ethnic conflict during the Pueblo I period.     

Eggshell and the archaeological record: new insights into turkey husbandry in the American Southwest

Eggshell in the archaeological record has interpretive potential beyond simple species identification. Structural features of eggshell itself indicate the degree of development of the embryo. Using a scanning electron microscope, a reference collection of modern eggshell characteristics has been produced that can be used for species determination and for the assessment of embryo development of prehistoric eggshell. We apply this technique to a sample of prehistoric eggshell from northwestern New Mexico and conclude that purposeful breeding of captive turkey populations is present during the 12th century AD. These preliminary results suggest a behavioral shift in turkey husbandry, concomitant with the well documented phenomenon of intensified turkey utilization after about AD 1100 in the American Southwest.     

Petrographic analysis and INAA geochemistry of prehistoric ceramics from Robinson Pueblo, New Mexico

The examination of thin sections is a successful method for discovering provenance groupings of archaeological ceramics if non-clay inclusions in pottery paste can be identified with petrographically distinctive geologic sources. When this is not the case, geochemical analysis must be employed to search for more subtle evidence of such groupings. This situation is likely to arise in studies, such as the present one, where the objective is to discern local or subregional patterns of pottery manufacture and exchange. Ninety potsherds from site LA46326 in New Mexico were subjected to both INAA and petrographic analysis. The results of this conjoint approach are assessed in relation to geochemical theory and are analysed graphically and statistically.     

Rock surface luminescence dating of prehistoric rock art from central Iberia

Rock art paintings are notoriously difficult to date numerically. Recently, luminescence dating has been shown to provide reliable rock surface burial ages in various archaeological settings. Here we use the cross-cutting relationship between a fallen rock and two paintings of the Iberian Levantine (older) and Schematic (younger) styles to constrain the age of the paintings by dating the rockfall event using rock surface luminescence dating. Infrared-stimulated luminescence (IRSL) signals as a function of depth into the buried face of the talus border indicate that the IRSL signal measured at 50°C (IR₅₀) was sufficiently reset to a depth of about 1.6 mm prior to burial. An uncorrected IR₅₀ age of 1.6 ± 0.2 ka was calculated for the rockfall event by dividing the surface equivalent dose (D_e) by the total dose rate. This age was corrected using both conventional and field-to-laboratory saturation approaches to yield indistinguishable ages of 2.7 ± 0.5 and 2.9 ± 0.3 ka, respectively. Since the panel with Schematic art was first available to the artist after the rockfall, we conclude the Schematic rock art at Villar del Humo is younger than ~2.9 ka. The Levantine rock art was painted on a panel constrained by the talus boulder before detachment, and so it is likely to be older than ~2.9 ka.     

Some thoughts on the factors that controlled prehistoric maize production in the American Southwest with application to southwestern Colorado

In this paper, we present a model of prehistoric southwestern Colorado maize productivity. The model is based on a tree-ring reconstruction of water-year precipitation for Mesa Verde for the period A.D. 480 to 2011. Correlation of historic Mesa Verde precipitation with historic precipitation at 11 other weather stations enabled the construction of an elevation-dependent precipitation function. Prehistoric water-year precipitation values for Mesa Verde together with the elevation-dependent precipitation function allowed construction of the elevation of southwest Colorado precipitation contours for each year since A.D. 480, including the 30-cm contour, which represents the minimum amount of precipitation necessary for the production of maize and the 50-cm contour, which represents the optimum amount of precipitation necessary for the production of maize. In this paper, calculations of prehistoric maize productivity and field life for any specific elevation are also demonstrated. These calculations were performed using organic nitrogen measurements made on seven southwestern Colorado soil groups together with values of reconstructed water-year precipitation and estimations of the organic nitrogen mineralization rate.

Changes in regional organization and mobility in the Zuni region of the American Southwest during the Pueblo III and IV periods: insights from INAA studies

The transition from the late Pueblo III (AD 1200–1275) to Pueblo IV (AD 1275–1400) period marks one of the most dramatic eras of demographic and social upheaval in the American Southwest. At this time, much of the northern Southwest was depopulated as thousands of ancestral Pueblo people moved to new homelands. In the Zuni region, this transition included a residential shift from dispersed, largely household-scale settlements to massive, multi-storied pueblos housing hundreds of people and a simultaneous contraction of regional settlement to a central core along the Zuni River and its major tributaries. This article presents a synthesis of our recent independent efforts to utilize instrumental neutron activation analysis (INAA) to investigate changes in social interaction in the Zuni region before and after this transition. We suggest that in addition to significant local and regional settlement shifts, the Pueblo III–IV transition in the Zuni region was accompanied by a major reorganization of pottery distribution networks as clear social boundaries began to emerge between village clusters. More generally, our combined study also highlights the iterative nature of INAA data analysis, the benefits of large sample sizes, and the utility of a diachronic interpretative approach.     

Working through theoretical tensions in contemporary archaeology: A practical attempt from southwestern Colorado

Archaeology should actively combine different paradigms to obtain a more complete understanding of the past. This paper argues for a practical combination of elements of the culture-historical, processual, and postprocessual approaches into a two-tier model. The first tierreconstructs the events of the past, using culture-historical and middle-range principles, and the secondconstructs a reflexive explanation of these events, which situates an analysis of the internal and external constraints on past human behavior within the specific theoretical and political positions of the analyst. The theoretical arguments are developed by means of an analysis of the prehistory of a segment of the mountains of southwestern Colorado.

Animate Objects: Shell Trumpets and Ritual Networks in the Greater Southwest

For over a millennium, shell trumpets have been an important part of Southwestern US ritual practice. We investigate the distribution of Southwestern shell trumpets, arguing that they are objects that are accorded animacy and can be used to track the history of different social networks. Using ethnohistoric and ethnographic documentation, at least two traditions of historically linked ritual practices are identified: one associated with serpent iconography and the other with curing, warfare, and sorcery. These two traditions represent enduring dispositions that link various regions of the Southwest through the introduction and adoption of ritual practices associated with migration and the transformation of late prehistoric societies.     

Removal of Rock Art Affected by the Raising of the Clanwilliam Dam Wall,Western Cape Province,South Africa: Techniques and Procedures

The commissioning by South Africa’s Department of Water and Sanitation of a new and higher wall for the Clanwilliam Dam will increase dam storage and provide additional water for emerging and existing commercial farmers. But there is a cost to South African heritage. The raising of the wall will flood 27 rock art sites as well as other archaeological and historical resources. In partial mitigation of this impact on heritage the removal of particular pieces of rock art was approved by Heritage Western Cape, the provincial heritage agency. This report focuses on the removal process and techniques used to cut out three pieces of rock art under the management of PGS Heritage between 18 April 2016 and 7 May 2016 from the sites designated CDE02 and CDW10. Publication of the techniques used and the procedures followed will add to the sparse literature on rock art removal and increase the accessibility and availability of information about the removed stones.     

Glaze-paints,technological knowledge,and ceramic specialization in the fourteenth-century Pueblo Southwest

The advent of glaze-painted ceramics by Ancestral Pueblo peoples in the US Southwest occurred during an important period of cultural change. In east-central Arizona, potters used glaze-paints to decorate a striking, representational-style pottery during the early fourteenth-century AD. We evaluate the possibility that these vessels were manufactured by emergent specialists who possessed crafting-knowledge that was not widely shared with others in their communities. Time of flight-laser ablation-inductively coupled plasma-mass spectrometry (TOF-LA-ICP-MS) was used to characterize the composition of a large sample of red ware sherds from sites in the Silver Creek area. This analytical approach precisely measures the chemical composition of paints, which can then be used to model ancient technological “recipes.” Our study highlights the complexities of craft production in small-scale societies and the utility of practice-based versus typological approaches to specialization.
