Abstract
The results of the x-ray fluorescence analysis (XRF) here of 148 obsidian artifacts from Late Archaic contexts at Crystal Cave (39LA504), western South Dakota indicates procurement of three major prehistoric obsidian sources in western Wyoming (Obsidian Cliff) and eastern Idaho (Bear Gulch and Malad; see Tables 1 and 2 and Figures 1 and 2 here).
