SOURCE PROVENANCE OF OBSIDIAN ARTIFACTS FROM ARCHAEOLOGICAL SITES IN THE EAST RANKIN VALLEY, BARRY M. GOLDWATER AIR FORCE RANGE, SOUTHWESTERN ARIZONA
Abstract
The analysis here of 18 obsidian artifacts from various sites in the east Rankin Valley on the Barry Goldwater Air Force Range (BMGR) yields a source provenance typical of various periods on the range, dominated by one of the two chemical groups of Sauceda Mountains, with Los Vidrios, and Los Sitios del Agua present in the minority (Martynec et al. 2011; Shackley 2005, 2012, 2014; Shackley and Tucker 2001).
