This thesis provides the first formal and phenomenological analysis of the architecture in Paquimé, otherwise known as Casas Grandes, Chihuahua, Mexico. The eastern and western halves of the city are divided by a stone wall and reservoirs. The monuments on the east are rectilinear, puddled adobe structures used primarily for domestic and manufacturing purposes. The buildings on the west, on the other hand, are open earth mounds lined in stone for public displays. This thesis analyzes each building individually, the relationship of the structures to one another, and the entire layout of Paquimé in order to better understand Paquimian visual culture.

The research presented here explores why a few people left their valley-dwelling neighbors to build and live at El Pueblito on Cerro de Moctezuma, the only hilltop settlement constructed during the Casas Grandes Medio period (A.D. 1200-1450) in what is today northwest Chihuahua, Mexico. These people also constructed the only currently recognized trails to a settlement, a massive rock agricultural system and subterranean oven, and an unparalleled crowning hill summit precinct. Comparative analyses of artifacts from limited excavations at El Pueblito to four other Medio period settlements shows that in terms of ceramics, chipped stone, and ground stone, El Pueblito was an ordinary residence. However, other evidence demonstrates that El Pueblito, and more comprehensively Cerro de Moctezuma, was beyond the ordinary. Wood preference, bird wings, remains of elk, an impractical use of construction materials, an imposing use of buildings, a unique architectural style, and an untypical settlement composition support a conclusion of specialized, ideological interests. Trails and wayside shrines at Cerro de Moctezuma were physical and symbolic places that initialized perceptions of the hill. Theories of ritualization, architecture, pilgrimage, and community; ethnographic analogy; and archaeological parallels provide vantages to orient Cerro de Moctezuma within a broader ritualized landscape of interactions involving hilltop shrines, feasting ovens, ball courts, and Paquimé, the premier capital of Medio times. Cerro de Moctezuma and Paquimé each concentrated the trappings of specialization. Tangible reproductions of ritual in the hinterland, such as ovens and ball courts, are less elaborately expressed than at Paquimé. Likewise, hilltop ritual facilities are most elaborate at Cerro de Moctezuma compared to those in the hinterland. Pilgrimage to both ritual centers as well as hinterland ritual leaders are envisioned. Within a trans-regional ideology and worldview of hill settlement and use, Cerro de Moctezuma was locally crafted from a ritual mandate to reinforce and maintain central beliefs and values emanating from Paquimé and was a physical and ideological part of that great center with ritual leadership residing periodically at both places.

In this study I analyzed the pattern of settlement for known Medio period (A.D. 1200–1450) sites in the Casas Grandes region of Chihuahua, Mexico. Locational data acquired from survey projects in the Casas Grandes region were evaluated within a Geographic Information Systems (GIS) framework to reveal patterns in settlement and site distribution. Environmental and cultural variables, including aspect, cost distance to nearest ballcourt, ecoregion, elevation, local relief, cost distance to nearest oven, cost distance to Paquimé, slope, soil, terrain texture, topographic position index, cost distance to nearest trincheras, vegetation, vegetation variety to 100 meters, vegetation variety to 500 meters, cost distance to nearest intermittent lake, cost distance to nearest intermittent stream, cost distance to nearest perennial lake, and cost distance to nearest perennial stream were calculated for each site in this region. It was expected that the relationships of correspondence between known sites and these variables would provide a quantitative framework that could be used to model the locational probability of unknown sites in the region. Through the use of GIS and statistical analyses, the results of this study were used to produce an archaeological site sensitivity map for this region of northern Mexico.

The Casas Grandes Valley is located in the northwestern corner of the modern state of Chihuahua, Mexico. This area falls into the greater Northwest/Southwest cultural region. Research conducted on Casas Grandes ceramics up to this point has focused on form and design in connection with burials, authority, sociopolitical organization, ceremony and ritual, communication, and identifying cultural boundaries and influences. Very little has been said about some of the everyday uses of Casas Grandes ceramics. My thesis explores the evidences of use on ceramic vessels in the Casas Grandes region during the Medio period (AD 1200-1450). I conducted a use-alteration analysis on the interiors and exteriors of 300 vessels. The purpose of this study was to examine the question: how were the vessels used by the people of Casas Grandes? These analyses suggest that the vessels were typically used for separate but not altogether distinct use activities. All vessels had some evidences of wear, regardless of vessel form, size, or decoration. The general use patterns followed some intended functional categories, with enough variety to suggest vessels were also used according to individual needs.

As part of a multinational project and with the help of other professionals, I gathered and analyzed 110 samples of dental calculus (fossilized plaque) from human remains discovered at Paquimé and the Convento site in the Casas Grandes River valley to identify various microfossils still present in the silica matrix. Once identified, I used the results to reconstruct human/plant relationships present during the Viejo (700-1250 CE) and Medio (1250-1450 CE) periods in and around Paquimé. My data suggest that maize was used throughout both time periods, supplemented by wild plants, and possible marine resources. Further, evidence for cultural food modification methods such as fermentation, roasting, grinding, and nixtamalization (an alkaline treatment of the grain) was present. The data suggest prehistoric plant use went beyond simple subsistence, being modified for use as part of non-subsistence activities.

This research addresses how interregional interaction changed between the Viejo period (AD 700-1200) and Medio period (AD 1200-1450) in northwest Chihuahua, Mexico. Non-locally procured or created artifacts, features, and iconographic elements are used as proxy evidence for past long-distance relationships. Data available in technical reports and other publications concerning these materials in Viejo period contexts and a sample of excavated Medio period sites are synthesized and presented. The data are used to create a geospatial dataset and distribution maps with quantities and contextual information for each of the nonlocal materials. I argue that interaction and social networks with long-distance neighbors were complex and widespread during both the Viejo and Medio periods. These intricate relationships morphed and altered in profound ways with the rise of the regional center Paquimé and the fluorescence of the Casas Grandes cultural tradition, but some of the fundamental relationships also remained the same.

The reasons for the abandonment of Paquimé are uncertain. The prevailing theory claims this geographic area endured centuries of warfare, ritual sacrifice, and at least one massacre; this theory is supported by numerous unburied bodies recovered at the site. These assertions of violence have never been corroborated by osteological data. Data were collected from a sample of Medio period (A.D. 1200-1450) human skeletal remains recovered from the 1958-1961 excavations at Casas Grandes. These data were synthesized with accelerator mass spectrometry radiocarbon dates, fluoride ion dates, population demographics, and burial context. Frequencies of ante-, peri-, and postmortem trauma were compared to other studies from the Old and New Worlds. I argue that warfare was not endemic to this region and that a massacre did not occur. Moreover, cannibalism and probably human sacrifice were practiced. I assert that these activities may have been related to the proliferation of the Mesoamerican ballgame in the American Southwest and to Paquimé's role as the distribution center of the region's ritual and exotic goods. This dissertation underscores the importance of including skeletal analysis with other lines of archaeological inquiry when answering questions about human behavior. / Committee in charge: John Lukacs, Chairperson, Anthropology; Guy Tasa, Member, Anthropology; Frances White, Member, Anthropology; John Orbell, Outside Member, Political Science

The Casas Grandes region of northern Mexico is an understudied, though important, part of the culture area that has come to be known as the Northwest/Southwest (NW/SW). What studies have been conducted in the Casas Grandes region have focused on the Medio Period (approximately 1200-1450 AD) and the large site of Paquimé. Only a small amount of research has been conducted on the preceding Viejo Period (approximately 700-1200 AD). In this thesis, I create a clearing house of published Viejo Period architectural features excavated in the Casas Grandes region. I also analyze those features to develop our understanding of the materials and technological choices used to construct these features, and to evaluate the validity of sub-regional zones which have begun to develop within the archaeological literature from this area. These analyses include a qualitative analysis of the excavated architectural features as well as statistical clustering methods, a Principal Components Analysis, and a Correspondence Analysis of available architectural data. I ultimately propose revisions to the existing architectural typology for the Viejo Period and the abandonment of the concept of sub-regional zones within the Casas Grandes region. I also observe some emerging patterns within the architectural data and suggest that further research is needed to fully understand the distribution of architectural features throughout the region.
