A Cultural Resource Survey of Reach 4, Granite Reef Aqueduct, Central Arizona Project

Under contract with the Bureau of Reclamation, the Office of Cultural Resource Management (OCRM), Department of Anthropology, Arizona State University, completed archaeological survey of Reach 4 and several access roads that would be modified for its construction. Reach 4 of the Granite Reef Aqueduct extends about 14 miles from the Hovatter Road exchange with Interstate 10 to the Centennial Wash Siphon Outlet.
This report describes the results of the archaeological surveys conducted along Reach 4 of the Granite Reef Aqueduct. Results suggest that the project area was part of a secondary resource zone, an area which apparently did not support a permanent population, but was utilized intermittently, probably on a seasonal basis. Most of the aqueduct traverses the Harquahala Valley, but a small portion falls on the edge of the Little Harquahala Mountains.
Twenty-two field loci, over 200 isolated artifacts, and 3 areas of historic trash were recorded during the Reach 4 survey. Based on relative density of cultural material dispersion, 19 of the field loci and the majority of the isolated artifacts were grouped into a single site, AZ S:7:13 (ASU).The site is of indeterminate age, although it is likely associated with the Hohokam or Yuman traditions.
