Archaeological Investigations at AZ AA:12:16 (ASM), the EK Ranch Site, Pima County, Arizona


In November 1997, Desert Archaeology, Inc., conducted archaeological testing along a portion of AZ AA:12:16 (ASM). According to the Arizona State Museum site card, this Hohokam site was originally recorded by Mitalsky, in 1937. Mitalsky found Hohokam pottery, cremated human bone, and ground stone scattered along the embankments and in adjacent cotton fields. In the years since the site card was filled out, this area has been extensively developed, with little additional archaeological work.

Desert Archaeology's 1997 testing program six trenches were excavated with a backhoe, resulting in the discovery of seven archaeological features. These features were documented by profile drawings and standard field forms. The features were identified as: a large borrow pit, an outhouse pit, a basin-shaped pit, a smaller borrow pit, a possible outhouse pit, a prehistoric firepit, and a small pit. All the features were located in Trench 1. The site was determined to be eligible for inclusion in the National Register under Criterion D, because it could provide significant information on the prehistoric and historic-period use of the area, and data recovery was planned. The research theme of the work was to study the history of human use of the evolving riverine environment in the middle Santa Cruz Valley. At AA:12:16, specific research domains that could be investigated were: (1) Variation in Settlement Form and Function; (2) Ceramic Container Technology; and (3) Historic Patterns of Floodplain Use (Gregory and Mabry 1998).

The results of data recovery at AA:12:16 are presented in this report. A review of the cultural and historical background for the area precedes a description of the results of data recovery and the Native American ceramic analyses. Work at the site was relatively limited, due to the presence of so few features. However, the archaeological excavations provided useful data, especially relating to both prehistoric and historic-period Native American ceramics.
