We used X-Ray fluorescence (XRF) spectroscopy to identify nine obsidian sources used by the prehistoric inhabitants of Jackson Hole, Wyoming. This paper examines this prehistoric use of obsidian and obsidian sources. Variation in utilization patterns is suggested through study of temporally diagnostic obsidian artifacts. The diachronic pattern of sources used allows consideration of the influences in acquisition, distribution, and use of obsidian.
