Archaeological Investigations at Christopher Columbus Park, Tucson, Pima County, Arizona (TR2007-8) (PDF)
AZ AA:12:96 (ASM): Phase 1 (Locus A, B, and C) surface collection and testing, and limited Phase 2 (Locus A) excavation. Environmental setting is the intersection of an alluvial fan with the floodplain of the Santa Cruz River. Surface artifacts include Early Agricultural period, Early Ceramic period, and Hohokam age material. Excavation of 175 features in five geomorphic strata dating to the Early Cienega phase. Features include three pit structures, 170 extramural pits, and four inhumations (two were excavated during Phase 1). Artifact density in features is low. Resource analyses indicate broad spectrum adaptation of wild foods and some maize. Feature analyses show a focus on wild food thermal processing. If future planned development at the park will impact archaeological deposits within the boundaries of AA:12:96, consultation and formulation of a new treatment plan are recommended.
AZ AA:12:105 (ASM): Phase 1 surface collection and testing investigated a portion of the Solar Well site, AA:12:105. Environmental setting is the intersection of an alluvial fan with the floodplain of the Santa Cruz River. Surface artifacts include Sedentary and Classic period Hohokam ceramic sherds, ground stone, and Early Agricultural period (San Pedro phase) flaked stone. Current park development plans do not include areas within the site boundaries. If future planned development at the park will impact archaeological deposits within the boundaries of AA:12:105, consultation and formulation of a new treatment plan are recommended.
AZ AA:12:980 (ASM): This Historic era canal winds in and out of the project area, following the contour of the land. The canal was evaluated and mapped. It has been thoroughly documented and researched, and substantial segments will be preserved within Christopher Columbus Park. No further archaeological investigations are recommended for this cultural resource. AZ AA:12:999 (ASM): Insufficient data were available on this Historic era homestead to make an eligibility recommendation. The homestead will not be affected by currently planned park development. If future planned development at the park should impact this site, a testing program should be implemented to determine the eligibility status of the site.
