The Cochran Survey on the Gila River


The Cochran Survey was administered over a period of 25 months, beginning in April 1998 and ending in May 2000. As funding became available delivery orders were submitted from the Bureau of Reclamation (Reclamation) to Archaeological Consulting Services (ACS) to increase the survey coverage under their Section 110 mandate. Initially, the survey included portions of the USGS 7.5' North Butte and Grayback quadrangles near the historic site of Cochran, and was later expanded to include a second area of non-contiguous parcels near the towns of Hayden and Winkelman, all in the Gila, and Salt River Baseline and Meridian, Pinal County, Arizona. For the purposes of organization, the two areas are referred to below as the Cochran unit and the Winkelman unit.
