Geologic setting

Geologic description

Johnson and Karl (1985) map the rocks in the area of this placer prospect as Mesozoic or Paleozoic amphibolite, gneiss, schist, and marble, intruded by a stock of Cretaceous or Jurassic diorite. The site is on a high-angle fault that strikes north; other high-angle faults in the area strike northwest. The only published information about the prospect is that it has been staked for placer gold (U.S. Bureau of Land Management, 2002).
