Archaeological Investigations at AZ BB:13:16(ASM)-Locus F, Tohono O'odham Indian Reservation, San Xavier District, Pima County, Arizona: Report

The Bureau of Reclamation (Reclamation) assisted the San Xavier District of the Tohono O'odham Nation with the construction of an extension of the Central Arizona Project (CAP) pipeline on reservation lands along the Santa Cruz River. The pipeline corridor crosses Loci F and H of AZ BB:13:16(ASM), a Hohokam occupation zone with many pithouses and other structures, varied pits, trash areas, and possibly human remains. Archaeological Consulting Services, Ltd. (ACS) provided the labor, transportation, equipment, applicable permits, specialized personnel, and materials to perform archaeological testing, site evaluation, and excavation of selected features within the pipeline right-of-way.

Archaeological resources at Locus F were investigated in two stages. An initial testing program, conducted under the first delivery order, evaluated the number and kinds of features present. The second stage of the project, conducted under the second delivery order, involved more intensive investigations to record and recover material in the direct path of the pipeline. Work also included a geoarchaeological reconnaissance of the surrounding land to study the relationship between different soil settings and the locations of archaeological sites.

This report presents the results of second stage of excavations.
