The analysis here of 30 obsidian artifacts from four sites in Wyoming is dominated by Obsidian Cliff, Yellowstone Volcanic Field obsidian, and a few from Bear Gulch, in the Centennial Mountains of northeastern Idaho (Table 1).  This combination of sources is common in archaeological contexts in the region, and in previous results from the Caldwell Creek Site (48FR7091; Shackley 2014).
