| DESCRIPTION
|
The Casa Diablo source complex is located within Long Valley Caldera, a large volcanic depression located at the eastern base of the Sierra Nevada Mountains in eastern California. The source complex is composed of three geochemically distinguishable subgroups - Lookout Mountain, Sawmill Ridge, and Prospect Ridge (Hughes 1994). Prehistoric use of obsidian from Casa Diablo, primarily from the Lookout Mountain and Sawmill Ridge sources, was extensive throughout eastern and central California. Evidence of trans-Sierran procurement and exchange of large quantities of glass from the source area is well-documented at many sites located in the west-central Sierra Nevada Mountains, the Central Valley, and the central and south-central coast of California.
Obsidian Hydration: Many different hydration rates have been proposed for obsidian from the Casa Diablo source complex. Induced hydration studies suggest a similar hydration rate as obsidian from the nearby Bodie Hills source.
