Partial reburial of West Ruin at Aztec Ruins National Monument

Abstract

Aztec Ruins National Monument is a World Heritage Site in northwestern New Mexico, USA. More than 50,000 visitors come to the site each year, specifically to visit West Ruin, a 12th–13th century, multi-storey Ancestral Pueblo an (Anasazi) village with over 400 rooms. West Ruin was excavated in the early 1900s and was intentionally left exposed for public access and interpretation. The walls, constructed of shaped sandstone blocks set in mud mortar, have gradually deteriorated, despite years of stabilization and preservation efforts. In 1999, park management began to partially rebury portions of West Ruin as a reversible long-term preservation treatment. While partial reburial allows for presentation of the site to visitors, it also results in uneven fill levels in many rooms. Differential fill levels can increase the area subject to migration and capillary rise of moisture through the walls, and can accelerate stone and mortar deterioration on the exposed wall faces. Differential fill levels can also lead to structural instability from unequal pressure exerted between filled and non-filled areas. To mitigate moisture migration and structural instability from differential fills, a soil retention system was designed and tested using layers of synthetic three-dimensional earth confinement cells. This paper discusses the design and implementation of the soil retention system within the larger context of a multi-phased reburial project underway at Aztec Ruins National Monument.     

Social Change and Hunting during the Pueblo III to Pueblo IV Transition,East-Central Arizona

Abstract

The transition from the Pueblo III to the Pueblo IV period (A.D. 1100–1400) in the American Southwest involved marked population aggregation. Diverse economic, political, and religious factors must have played a role in the integration of these populations. Bailey Ruin, Bryant Ranch, and Pottery Hill, three sites in the Silver Creek drainage of east-central Arizona, show increased hunting of large mammals during this transition. This trend has elsewhere been attributed to hunting specialization due to local resource depletion and perhaps the need for a seasonal supplement to maize-based diets, but these factors do not adequately explain the data here. In fact, the regional reliance on rabbit protein suggests that hunting larger game was not necessary to meet dietary needs in an environment where small game is a reliable food source and artiodactyls are rare. Rather, the increased proportion of large mammals in the Silver Creek area faunal assemblages seems to reflect larger issues of social reorganization. Rituals aimed at community integration and individual attempts to gain authority and prestige were focused on communal hunts, feasts, and the production of ritual paraphernalia through large-game hunting.     

Pueblo Settlement,Architecture, and Social Change in the Pueblo Revolt Era,A.D. 1680 to 1696

Abstract

In A.D. 1680, the Pueblo Indians of the American Southwest united in a revolt that drove Spanish colonists out of Pueblo lands for more than a decade. Dramatic changes in the architecture, spatial organization, and settlement patterns of Pueblo villages occurred during this era as Pueblo leaders sought to revive traditional beliefs and practices. Semiotic and space syntax analyses of 10 Pueblo Revolt-era (1680–1696) villages reveal evidence for an ideology of cultural revitalization, as well as changing patterns of leadership and social interaction. Villages built early in this period exhibit planned communal construction and evidence of strong centralized leadership that resulted in highly structured social interaction. In contrast, later villages are characterized by less centralized leadership and a dispersed layout that facilitated the informal interactions necessary for communal integration in a time of increased migration. The social changes reflected in and shaped by Revolt-era architecture were crucial in the formation of modern Pueblo culture, influencing village alliances and spatial organization down to the present day.     

“…being weary,they had rebelled”: Pueblo subsistence and labor under Spanish colonialism

Native American responses to Spanish colonialism are explored through an analysis of multiple lines of evidence concerning subsistence practices, diet, and health in the Salinas Pueblo area of central New Mexico. Zooarchaeological and paleoethnobotanical data from three Pueblo villages that experienced different degrees of Spanish missionization are the focus of this study. In addition, human osteological data from one village provide important information on activity patterns and health. These data are used to document the kinds of changes that occurred in Pueblo labor patterns, food consumption, and health from the pre-colonial to colonial periods. Synthetic analyses document the development of some degree of inter-village specialization in large game hunting, hide processing, and corn farming, presumably in response to Spanish tribute levies in corn and antelope hides, and demands on Pueblo labor in other arenas. There also appears to be a degree of divergence in women’s and men’s lives in the colonial period. These southwestern data are then compared with similar information from the southeastern US to identify patterns of similarity and difference in Native American experiences of and strategies for dealing with Spanish colonization.     

Pervasiveness of phytoliths in prehistoric southwestern diet and implications for regional and temporal trends for dental microwear

Our previous analysis of phytolith content of coprolites showed that calcium oxalate phytoliths from desert food plants caused dental microwear among prehistoric Texas hunter-gatherers. We demonstrated that phytoliths from desert succulents were ubiquitous and abundant in hunter-gatherer coprolites. We found that calcium oxalate phytoliths were harder than human dental enamel. We concluded that phytoliths from desert succulent plants caused dental microwear and hypothesized that such dental microwear would be common in other desert hunter-gatherer and horticultural peoples. Presented here are further analyses of phytoliths from coprolites. Two additional hunter-gatherer sites and three Ancestral Pueblo (Anasazi) horticultural sites are included in this study. Calcium oxalate phytoliths are ubiquitous in coprolites from hunter-gatherer sites in the Mojave Desert and the Colorado Plateau. For the three Ancestral Pueblo sites, calcium oxalate phytoliths from desert succulents (agave family and cactus family) are the most common types of phytoliths encountered. However, silica phytoliths are also present in Ancestral Pueblo coprolites. The data demonstrate that phytoliths from non-cultivated desert plants were a source of dental microwear for the pre-maize Archaic hunter-gatherer bands and maize-reliant Ancestral Pueblo villages.     

High precision isotopic analyses of lead ores from New Mexico by MC-ICP-MS: implications for tracing the production and exchange of Pueblo IV glaze-decorated pottery

Between ca. 1275 and 1700 CE, Pueblo groups in the northern Southwest United States produced and exchanged ceramic bowls decorated with lead-based glaze paints. Previous studies of these glaze-decorated bowls have used lead isotopic analysis by ICP-MS to identify the sources of lead used by Pueblo potters, and investigate how social or economic factors may have influenced resource use among different Pueblo communities (e.g. 13 and 14; Huntley et al., 2007; Huntley, 2008). However, interpretations of much of this isotopic data have remained provisional because of overlap among the isotopic ratios of potential sources and because the isotopic composition of many glaze paints do not clearly match any known source. Here, we use multi-collector ICP-MS to re-measure the lead isotopic composition of 48 samples of lead sulfide (galena) and lead carbonate (cerussite) from sources in New Mexico that were potentially utilized by Pueblo potters, including mines within the Cerrillos Hills, Magdalena, Hansonburg, and Joyita Hills mining districts. These results define the isotopic composition of lead ores from these districts with greater precision and accuracy than achieved in previous studies and better distinguish among these mining districts in lead isotope space. Most significantly, we find that galena mineralization within the Cerrillos Hills only has a modest degree of isotopic variation, with ²⁰⁶Pb/²⁰⁴Pb ratios from 18.508 to 18.753, ²⁰⁷Pb/²⁰⁴Pb ratios from 15.580 to 15.607, and ²⁰⁸Pb/²⁰⁴Pb ratios from 38.388 to 38.560. These ranges are far narrower than previously reported, and should supersede previously published values for this district. In total, we conclude that isotopic measurements of both ores and glaze paints made by MC-ICP-MS will provide new information about the provenance of lead in glaze paints and allow for more detailed interpretations about resource procurement and exchange in the Pueblo world.     

How the Pueblos Got Their Sprachbund

Pueblo societies comprise a culture area, and a zone of linguistic convergence or Sprachbund, that encompassed four distinct language families. Pueblo groups are also quite genetically homogeneous. The general forces promoting or diluting cultural differences across groups are defined and given a preliminary weighting through time for Pueblo societies. The Neolithic demographic transition and the hierarchical society transition (defined herein) contribute to homogeneity across groups derived from a single descent group, but create differences among groups derived from different descent groups. High mobility across communities and across regions contributes to cultural similarities across phylogenetically defined groups, as may adaptation to similar environments. Pronounced tendencies towards within-group conformity and linguistic purism were probably late (i.e., early first-millennium ad) developments in the Pueblo world.     

The Prehistoric Local Environment of Grasshopper Pueblo,Arizona

Abstract

The prehistoric local environment near Grasshopper Pueblo, east-central Arizona, is reconstructed by analysis of mammalian microfauna recovered at the site. Changes in the vegetation surrounding the pueblo during the span of occupation (ca. 1300–1400 A.C.) are described and the present and past environments at the site are contrasted. Paleoenvironmental analyses to date have failed to produce evidence for a rapid prehistoric climatic shift with negative consequences for agricultural productivity.     

BLOOD FOR THE GHOSTS: READING RUIN'S BEING WITH THE DEAD WITH NIETZSCHE

A focus on roots, localizations, usurpations, and obliterations together with commemoration and different fields of scholarly research, along with a thematic focus on Homer's Nykia, permit Hans Ruin to revisit the foundations of history in Being with the Dead. Ruin draws on cultural sociology, including the work of Alfred Schütz, as well as Heideggerian historicity and the dead of the distant past, including archaeology and ethnography, paleography and physical anthropology. Ruin also engages Michel de Certeau's Writing of History and its focus on the other in a necropolitical account tracked through interdisciplinary fields. In my reading I supplement Ruin's critical focus on Homer scholarship beyond the twentieth century with a return to Nietzsche's nineteenth-century emphasis on the “blood” needed to bring the voices of the past to speak in his own reading of Homer. To do this, I note the dead-silenced (“zombie”) scholarship haunting Nietzsche's voice in his field of classical philology in addition to Nietzsche's source scholarship and his hermeneutic methodology of historiographical research for the sake of ethnography, archaeology, and Nietzsche's lectures on pre-Platonic philosophy.     

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.     

Dogs,Deer, or Guanacos: Zoomorphic Figurines from Pueblo Grande,Central Arizona

Abstract

Excavations at the large Hohokam site of Pueblo Grande, one of the most important of the Salt River valley villages of central Arizona, recovered an unusual group of zoomorphic ceramic figurines dated to the Preclassic, between A.D. 950/1000 and 1100/1150. The figures, quadrupeds with raised tails and ears, were found in a Sacaton phase pithouse and are thought to be part of a ceremonial offering or act. This study describes the figures and suggests they represent dogs rather than deer or the South American camelid, the guanaco. The Pueblo Grande figures are compared with similar figures from other parts of the Hohokam world.     

Cacao consumption during the 8th century at Alkali Ridge,southeastern Utah

Theobroma cacao was detected in the ceramic assemblage at the 8th century Site 13, Alkali Ridge, southeastern Utah. The presence of this Mesoamerican beverage during the Pueblo I period is the earliest reported use of cacao in the northern American Southwest, coming centuries earlier than the recently documented Pueblo II consumption of cacao in cylinder jars, sharp-shouldered pitchers and shallow bowls at Pueblo Bonito, Chaco Canyon. Analogous to the situation at Chaco, cacao was found at Site 13 in a new vessel form decorated with a distinctive design system that contrasted markedly with designs and vessel forms in the local black-on-white ceramic assemblage. We postulate that Abajo R/O at Site 13 represents a ceramic tradition brought by one of the many groups moving into the northern Southwest. The detection of cacao in their ceramic vessels represents new evidence for the migration model that for centuries brought people with Mesoamerican beliefs, ritual practices and a new subsistence lifeway into the American Southwest.     

Intermarriage,Technological Diffusion,and Boundary Objects in the U.S. Southwest

This article draws upon ethnographic accounts of female potters’ movement and intermarriage into multi-ethnic Pueblo communities in the U.S. Southwest to illustrate how marriage networks created opportunities for innovation through the production, distribution, and consumption of boundary objects. These objects did not define boundaries but facilitated boundary crossing or bridging by potters. I argue that the concept of boundary objects is more useful than hybridity for understanding the processes of culture contact and material culture diffusion. Archaeological evidence for late twelfth through thirteenth century migrations from the Four Corners to the southern Colorado Plateau is used to make a case for a high degree of intermarriage and post-marital movement of women. Such patrilocality challenges normative views of post-marital residence, including those employed by early ceramic sociologists working in the same area of the Southwest and even at the same sites. The case that I discuss provides a contrast to other Southwest examples in which conformist transmission was more common, and helps to solve a paradox in explanations of the Southwest Pueblo Sprachbund. I conclude that the concept of boundary objects complements formal social network approaches in archaeology by bringing out the active role of objects in linking social actors.     

Possible sources of archaeological maize found in Chaco Canyon and Aztec Ruin,New Mexico

Maize played a major role in Chaco's interaction with outlying communities in the southern Colorado Plateau. This paper seeks to determine where archaeological corn cobs brought to Chaco Canyon were grown. Strontium-isotope and trace-metal ratios of 180 soil-water and 18 surface-water sites in the Southern Colorado Plateau have revealed possible source areas for some of 37 archaeological corn cobs from Chaco Canyon and 10 archaeological corn cobs from Aztec Ruin, New Mexico. The most probable source areas for cobs that predate the middle-12th-century drought include several Upper Rio Chaco sites (not including Chaco Canyon). There are many potential source areas for cobs that date to the late A.D. 1100s and early 1200s, all of which lie in the eastern part of the study area. Some Athapascan-age cobs have potential source areas in the Totah, Lobo Mesa, and Dinetah regions. One Gallo Cliff Dwelling cob has a strontium-isotope ratio that exceeds all measured soil-water values. Field sites for this cob may exist in association with Paleozoic and Precambrian rocks found 80–90 km from Chaco Canyon. Potential source areas for most Aztec Ruin cobs (many of which were found in rooms dating to the first half of the 13th-century) appear to be associated with a loess deposit that blankets the Mesa Verde and McElmo Dome regions.     

A Reinterpretation of the Occupational History of the Pendleton Ruin,New Mexico

Abstract

The Pendleton Ruin, an adobe pueblo of approximately 125 rooms in the “boot heel” of sw New Mexico, was excavated by Alfred V Kidder, C. Burton Cosgrove, and Harriet S. Cosgrove in 1933. It defined the Animas phase, dated between A.D. 1150 and 1450. In this paper, the occupational history of the Pendleton Ruin is reexamined, beginning with the excavators' assumption that the lack of trash accumulation indicated a brief occupation. Based on the published report, field notebooks, and collections, it is concluded that the site was occupied longer than thought. Evidence for at least one hiatus in occupation may explain how a long occupation is compatible with low artifact yields. Evidence also points to the construction of a platform mound along the northern side of a plaza. A reinterpretation of regional settlement and social organization, focused on the role and scale of settlement instability, is presented. Finally, the results present a case study of how reanalysis of excavated materials can be a useful archaeological practice.     

War and Place: Landscapes of Conflict and Destruction in Prehistory

Abstract

The concept of place has rarely been applied to the archaeological study of warfare. Given that cultural landscapes embody meaning, however, the idea that places can be the focus of competition makes it evident that they can also shape associated conflict. As archaeologists move toward a more nuanced study of conflict in the past, such considerations will take on increasing importance, although as of yet most such studies are heavily reliant on textual sources and overtly symbolic material culture. This paper presents a case study from Burnt Corn Pueblo, in the Galisteo Basin, New Mexico, USA, and argues that evidence for conflict there at the beginning of the 13th century CE can be usefully interpreted through Ancestral Pueblo concepts of place.     

The Virgin Anasazi,far western Puebloans

In the American Southwest, the Virgin Anasazi region included the western part of the Colorado Plateaus and the river valleys of the adjoining Mojave Desert in Utah, Nevada, and Arizona. This occupation spanned the Puebloan periods from Basketmaker II to Early Pueblo III, roughly A.D. 1 to A.D. 1200. Virgin Anasazi subsistence combined cultivation with hunting and gathering. Current research is unveiling a prehistoric society with flexible food procurement strategies and group organization. They underwent a version of the pit house-to-pueblo transition familiar from the Kayenta and northern San Juan areas. Both intra- and interregional exchange seems to have peaked in Late Pueblo II times and then fallen off prior to the end of their culture history. Face-to-face communities remained small, even into the late 1100s, when other Anasazi areas saw the beginnings of aggregation. Their fate, early in the widespread abandonment of the northern Southwest, remains to be understood.     

The role of a Chaco-Era great house in the Southern Cibola Region of West-Central New Mexico: The Largo Gap great house community

Largo Gap is one of several late Pueblo II (a.d. 1050–1130) Chaco-style great houses located in the southern Cibola region of west-central New Mexico. This region is at the interface of two Southwestern cultural areas: Mogollon and Pueblo. We report results of survey and excavation research at the Largo Gap great house and associated community to explore the role great houses in this region served for local populations, as well as their articulation with other great houses across the “Chaco Sphere.” The results identify Largo Gap as an architecturally “Chacoan” structure and that use of this structure incorporated both Mogollon and Puebloan material culture. The use of ceramics from both ancestral culture groups indicates that the local community was multi-ethnic, and suggests a socially-integrative role for the great house within this region.     

Lead isotope analysis of intra‐skeletal variation in a 19th century mental asylum cemetery: diagenesis versus migration

Living bone sequesters environmental lead (Pb) from both inhalation and ingestion, providing a record of Pb exposure over a lifetime. Questions about the effects of diagenesis and how to remove them have hampered most isotopic and elemental determinations. As a result, researchers often restrict their analyses to tooth enamel, despite its limitations. We report Pb isotopes in teeth and bones in a frontier population of 15 individuals from a late 19th century mental hospital graveyard in Pueblo, Colorado, a town active at that time in the smelting of ores. Analysis of lead isotopes sequestered in healing bone from rib fractures gives an isotopic fingerprint from the last few months of individual's lives. When bone tissues or teeth from different stages of life are analysed, life history trajectories such as migration routes can be developed which are partially self‐correcting for diagenesis.
