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 (Reference): Primary Reference = Cobb, 1973
Comment (Workings): Workings / Exploration = Surface.
Comment (Geology): Geologic Description = Eluvial placer 200 m long, less than 10 m wide and about 2 m thick in high, steep and dry tributary to Riley Creek. Much of Au in bedrock crevices; also visible free Au is in quartz veins in drainage basin. Basin contains colluvium composed of slate, limestone and quartz gravel, and a few large greenstone boulders, up to 2 ft (0.6 m) in diameter, probably of glacofluvial origin (Fritts, 1970, p.58)
Comment (Deposit): Other Comments = Area mined was a high, steep, and dry tributary of Riley Creek (Smith and Mertie, 1930, p. 336).
Comment (Deposit): Model Name = Placer
Comment (Exploration): Status = Inactive
