The Eastern Mining Area 115 KV Transmission Line Survey: Archaeological Resources in the Salt-Gila Uplands of Central Arizona


SWCA, Inc., Environmental Consultants (SWCA), of Tucson, Arizona, conducted the Eastern Mining Area (EMA) survey project under contract to Salt River Project (SRP) between October, 1993, and February, 1994. One central purpose of the project was to create an inventory of archaeological resources to assist in the planning of future improvements and other modifications to existing SRP transmission lines. The project included 107 person-field days of Class III archaeological survey along approximately 257 linear miles of existing 115 kV transmission lines and 92 linear miles of existing and proposed access roads in Pinal and Gila counties, Arizona.

The initial field survey was conducted between November 1 and December 10, 1993, and subsequent reconnaissance visits were made through March 1996 to address particular issues. The survey resulted in the recording of 81 new archaeological sites and the reevaluation of 40 previously recorded sites. The 121 sites within the transmission line rights-of-way include Archaic lithic scatters and possible Archaic roasting pits; Hohokam and Salado field houses, farmsteads, hamlets, villages, compound pueblos, rockshelters, agricultural sites, canals, ambiguous sherd and lithic scatters, and resource procurement and processing sites; Yavapai and Apache wickiup encampments; and historic Euroamerican townsites, habitations, dumps, trash scatters, and rockshelter encampments.

A second purpose of the project was to assess the cultural context of the sites by conducting an exhaustive review of the existing records on archaeological sites and survey projects within a two-milewide corridor centered on the targeted transmission lines. This archival component resulted in the documentation of over 100 previous survey projects and over 850 archaeological sites distributed along this corridor.
