Ceramics from three Utah great houses, Bluff, Cottonwood Falls, and Edge of the Cedars, were analyzed and compared with ceramics from Three Kiva Pueblo, which is not a great house site but was occupied contemporarily. Data on jar and bowl rim diameters were considered to understand great house feasting dynamics. Cooking jars with large rim diameters were more common at Three Kiva than they were at the great houses. This suggests that Three Kiva residents prepared large batches of food more frequently than great house residents. Distributions of Mancos Black-on-white bowl diameters were very similar at great houses and Three Kiva, but Three Kiva had bowls with larger diameters than those found at the great houses. Jar sizes suggest it is possible that feasting at great houses took place with a potluck model; however, bowl sizes suggest that Three Kiva also hosted feasts. Data on ceramic origins were considered to look for direction and strength of relationships with outside regions. All of the great houses had higher proportions of imported ceramics than Three Kiva, suggesting that great house residents interacted with people from other regions more frequently. All sites had large proportions of imported ceramics from the Kayenta region. All great house sites had Chuskan and Cibolan sherds, suggesting interaction with Chaco Canyon. Proportions of imported ceramics and the regions from which they came varied for each site, indicating that site residents maintained independent connections to people living in other regions.

This thesis presents the results of a multi-disciplinary investigation of a variant Ancestral Pueblo mortuary rite at Wallace Ruin, southwest Colorado (USA). This multi-storey building is one of four Lakeview Group great houses connected to the Pueblo II regional system centred at Pueblo Bonito of Chaco Canyon some 100 km to the south. From c. AD 1060-1150, Wallace Ruin functioned as a ritual-economic centre with a small residential component. Then, habitation of this great house, the Lakeview Group and all domiciles within 10 kilometres ceased. However, three or more decades later at least six rooms were used as a non-residential, Pueblo III mortuary facility for a minimum of 32 individuals. This utilisation was in marked contrast to the enduring Ancestral Pueblo practice of residential burial, usually in the extramural midden. The interrogation of several hypotheses regarding this anomaly entails a bioarchaeological approach that integrates skeletal evidence with spatial analyses regarding diachronic mortuary location choices at Wallace Ruin. Taphonomic methods that segregate bone displacements during corpse decomposition in a filled versus a void space provide accurate determinations of the depositional versus discovered mortuary microenvironments. The diachronic analysis of data from roughly 200 San Juan Region sites reveals additional ways in which Wallace’s Pueblo III mortuary program departs from longstanding communities of practice, whether great house or domicile. Chief among these are the use of a surface room floor and the postural arrangement of supine bodies with knees upright. These results, in combination with material culture evidence, form the basis of this thesis: The Pueblo III mortuary program at Wallace Ruin is a variant rite that entails a Mesa Verde Region reformulation of a Pueblo Bonito house society. The sanctioned retrieval of objects of memory offers a plausible explanation for intentional intrusions into two mortuary contexts. Beyond addressing questions concerning Wallace Ruin, a major contribution of this study includes advancement of the house society model as an interpretive scheme for evaluating Mesa Verde Region socio-ritual dynamics. This research also demonstrates the effectiveness of anthropologie de terrain (Duday, 2006) to retrospectively determine the original status of Ancestral Pueblo mortuary microenvironments. The refinement developed for this study, in which Range of Motion criteria are used to detect large-scale movements of lower limbs during corpse decomposition, is suitable for bioarchaeological analyses the world over.
