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 = Foley and Barker, 1985
Comment (Deposit): Model Name = Podiform chromite (Cox and Singer, 1986; model 8a).
Comment (Deposit): Other Comments = Site is located within Kodiak National Wildlife Refuge.
Comment (Geology): Geologic Description = At this chromite occurrence, one of several in the Halibut Bay ultramafic complex, massive chromite segregations occur in dunite rubblecrop near a small shear zone. Because of lack of exposure no other data are available.? the Halibut Bay ultramafic complex, consisting mostly of dunite, gabbro, pyroxenite, and periodite, occurs within sedimentary units of the Uyak formation of Cretaceous age.
Comment (Exploration): Status = Inactive
