An former underground asbestos mine/occurrence located in secs. 4 & 5, T7N, R14E, along Ash Creek, on National Forest land. Owned by the Arizona Asbestos Association.
Mineralization is hosted in the Mescal Limestone and is formed through metamorphic action of diabase intrusives upon Precambrian Mescal Limestone.
The limestone upon the east side of Ash Creek is much broken and dislocated by the irregular, roughly dike-like mass of diabase, and the greatest amount of chrysotile generally occurs where the irregularities or uprisings of the diabase contact are most pronounced.
Two prominent veins of asbestos commonly occur within about five feet of each other.
Workings are comprised of over 7,000 feet of underground workings. The longest tunnel is about 600 feet long.
