Geologic descriptionJohnson and Karl (1985) map the rocks in the area of this prospect as Cretaceous melange. The rocks are cut by northwest-striking, high-angle faults; these include the northwest extension of the fault at the Hirst Mine, which controls the mineralization there. Its trace is about a mile southwest of this prospect. The only published information about the prospect is that it is a lode claim staked for an unspecified commodity (U.S. Bureau of Land Management, 2002).
