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 = Degenhart and others, 1978
Comment (Deposit): Model Name = Stream placer (Cox and Singer, 1986; model 39a)
Comment (Deposit): Other Comments = If claims are still valid on this site, they are surrounded by Gates of the Arctic National Park and Preserve, where prospecting and mining have been prohibited since 1981.
Comment (Geology): Geologic Description = Placer gold may be derived from nearby pyritic quartz veins in phyllite of the Hunt Fork Shale (Degenhart and others, 1978). A few tens of ounces of gold per year were being produced for several years in the mid-1970's; production may have continued for some further uncertain period. No record of mining prior to 1970's nor any record of substanital production in recent years.
Comment (Workings): Workings / Exploration = Minor gold production using small-scale, non-mechanized methods up to about 1978. Production of gold amounted to a few tens of ounces/year (Degenhart and others, 1978).
Comment (Exploration): Status = Probably inactive
