About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = Type of workings: Surface and underground. Vigorous mining in early 1900's (a shaft on main stream did not hit bedrock). Several placer claims are included in this site description.

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)

Comment (Geology): Geologic Description = Host is alluvial gravels. Some colors of gold from a blue-gray gravel bed 9 ft (3 m) thick, about 100 ft (30 m) below surface.

Comment (Reference): Primary Reference = Chapin, 1918

Comment (Geology): Age = Quaternary
