A San Pedro Phase Agricultural Field and Early Ceramic Period Occupations in the Middle Santa Cruz Valley, Southern Arizona: Investigations at the Stewart Brickyard and Rillito Loop Sites

Summary

Arizona Department of Transportation (ADOT) proposed widening Interstate 10 (I-10) between Cortaro Road and Tangerine Road in northern Pima County, Arizona. Desert Archaeology, Inc., was contracted to mitigate the potential effects construction would have on significant cultural resources. A phased data recovery program was completed that addressed construction impacts at five archaeological sites along the l-10 corridor. Phase 1, exploratory trenching, tested for subsurface deposits at AZ AA:12:51 (ASM), AA:12:252 (ASM), AZ AA:12:486 (ASM), and AZ AA:12:256 (ASM). Cultural deposits were not identified in the project area at AA:12:486 or AA:12:256, and these two sites were excluded from further work. Phase 2 investigations, consisting of horizontal mechanical stripping and hand-excavation, mitigated the remaining two sites and revealed a canal complex recorded as AZ AA:12:961 (ASM).

Results as a whole for the project area indicate a sequence of small, dispersed activity locales, which were occupied intermittently over an exceedingly long duration of time. AA:12:252 included a small, limited-activity area consisting of clustered pits that date from the Agua Caliente phase to the Tortolita phase. Components at AA:12:51 are not dissimilar, and indicate occupations perhaps as early as the unnamed phase, with reoccupations during the San Pedro, Tortolita and Early Rincon phases. Environmental and subsistence data, artifacts, and features were generally infrequent at the investigated sites, making interpretations tenuous. The most significant finding was a San Pedro phase irrigated field system and associated canals, AA:12:961, at AA:12:51. Multiple crops were grown during a limited interval, and the structure of the field demonstrates a high degree of irrigation competency.
