Stratigraphy and Geochronology of La Playa Archaeological Site, Sonora, MexicoCopeland, Audrey Elizabeth; Quade, Jay; Watson, James; McLaurin, Brett; Villalpando, Elisa (The University of Arizona., 2011-05)The current study examines the stratigraphy, geochronology, and paleoecology of La Playa, an Early Agricultural period archaeological site (3600-1800 BP) located in northern Sonora, Mexico. We distinguished seven stratigraphic units ranging in age from >44,570 to 680 cal yr BP. All of the cultural remains are contained in Unit B, which spans from 4700-1580 BP. Deposits from Unit B represent overbank deposition from the nearby Rio Boquillas. The majority of cultural materials come from Units B4 and B5, which correspond to the Cienega phase (2800-1800 BP) of the Early Agricultural period. This period coincides with the first sedentary agricultural populations in the region and is marked by thousands of archaeological features including roasting pits, human burials, and extensive canal systems at La Playa. The presence of semi-aquatic and aquatic snails demonstrates that water was present year round in the canal system. The stable and radiometric isotopic evidence suggests that the early agriculturalists diverted ground water, likely from the nearby Rio Boquillas. Cultural remains from Unit C spanning the period <1580-680 BP are rare, suggesting major population decline during this time. There is little to no evidence of bioturbation in Unit C, suggesting that the landscape was thinly vegetated at this time. La Playa has experienced up to five meters of erosion during historic times, exposing a complex alluvial stratigraphy and numerous cultural features, which has greatly complicated archaeological interpretations at the site.
Violence and Recidivism at Point of Pines and Turkey Creek Pueblo Through Cranial AnalysisWatson, James; Lacroix-Martin, Jillian (The University of Arizona., 2013)This thesis documents the incidence of cranial trauma from the Mogollon sites of Turkey Creek and Point of Pines Pueblo, spanning the time from A.D. 1000- 1450. The Mogollon were located in the American Southwest and during this time period the population began to coalesce and eventually dispersed. This dispersal led to increased warfare and pillaging of resources and women and represents a time of considerable social change and tension throughout these two regions. The comparisons of cranial trauma made by placement of trauma on cranium, sex of the individual, and also the number and sex of individuals with evidence of recidivism may suggest the use of domestic violence towards women in the population. This is important because it may provide a snapshot into the violence that was used among the Mogollon. Data found that out of 518 skeletal samples, 40 (7.72%) showed signs of cranial trauma. Out of these 40 subjects there were 19 females (47.50%), 16 males (40.00%), 1 sub-adult (2.50%), and 4 unknown (10.00%). Out of these 40 subjects, 7 females (17.50%) and 5 males (12.50%) showed evidence of recidivism. By mapping cranial trauma based upon sex on one skull, the pattern of injury for females were found to be more centrally located on the frontal bone and along the saggital suture and more randomized all around the skull for males. Although these results were in accordance with the hypotheses tested for in this experiment, the results were too close to provide adequate support for domestic violence against women in these pueblos during this time period.
