The Lower Snake River (upstream of the Nome airport) 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 (Workings): Workings / Exploration = Remnants of dredge tailings may locally be present.
Comment (Exploration): Status = Probably inactive
Comment (Geology): Geologic Description = Fine gold was discovered on the bars of lower Snake River in 1898 (Schrader and Brooks, 1900). This location was plotted separately by Cobb (1972 [MF 463]) and some placer tailings appear to be present. Dredge operations took place on lower Snake River between 1919 and 1924 (Cobb, 1978 [OFR 78-9]). At least some of the dredge operations were part of a harbor-deeping project, and gold recovery was incidental. This part of Snake River reworks coastal plain deposits, and some richer gold concentrations may at least locally be present.
Comment (Reference): Primary Reference = Cobb, 1978 (OFR 78-93)
Comment (Deposit): Model Name = Alluvial placer Au (Cox and Singer, 1986; model 39a).
Comment (Geology): Age = Holocene.
