The analysis here of 63 obsidian artifacts (three are not obsidian) from five sites in southwestern Utah, indicates a source provenance assemblage with artifacts mainly produced from two sources in southwestern Utah, Modena in Iron County and Wild Horse Canyon in Beaver County, and the Kane Springs source in Lincoln County, Nevada (Haarklau et al. 2005; see cover image,Tables 1 and 2, and Figures 1 and 2).  One small piece of debitage was produced from the Obsidian Cliff source in the Yellowstone Plateau of northwestern Wyoming (source data at laboratory).  Obsidian Cliff obsidian does occur in early contexts throughout the West and into the Middle West (Beck and Jones 2011; Davis et al. 1995; Scheiber and Finley 2011; Shackley 2014, 2017).
