Archaeological Research Facility

The analysis here of 19 obsidian artifacts from 48PA3604 in Wyoming is dominated by Obsidian Cliff, Yellowstone Volcanic Field obsidian as in previous projects in the region, with two artifacts produced from the Malad, Idaho source (see cover image and Table 1 and Figure 1).  One artifact is produced from an, as yet, unlocated source that was not in the Skinner/Shackley North American obsidian source database.
