The Unalakleet River is a gold mine located in Alaska.
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 (Geology): Age = Quaternary.
Comment (Reference): Primary Reference = Schrader and Brooks, 1900
Comment (Workings): Workings / Exploration = Some prospecting took place along the Unalakleet River in 1898 (Schrader and Brooks, 1900).
Comment (Deposit): Model Name = Placer gold (Cox and Singer, 1986; model 39a)
Comment (Exploration): Status = Probably inactive
Comment (Geology): Geologic Description = The rocks in the vicinity of the Unalakleet River consist mostly of graywacke, shale, grit, and conglomerate of the Cretaceous Shaktolik Group (Cass, 1959). An intrusive body of unspecified composition is located approximately 5 miles south of the river and 7 miles south of the boundary of Holy Cross quadrangle; it is partially buried by sediments from the river (Cass, 1959). Schrader and Brooks (1900) report gold discoveries along the Unalakleet River during the fall of 1898, but there are no more recent reports of gold there.
