The Thunderbird Creek is a chromium 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 (Deposit): Model Name = Podiform chromite or Alaskan PGE (Cox and Singer, 1986; models 8a or 9)
Comment (Reference): Primary Reference = Rose, 1966
Comment (Geology): Geologic Description = Jurassic dunite of the Eklutna Sequence contains chromite-rich bands. Chromite occurs as discontinuous stringers and lenses of varying grades. Although the exposure is not as good, this prospect appears to be similar to many in the general area (Rose, 1966). See West Twin Peak occurrence ARDF number AN096, Highway prospect ARDF number AN095, and Pioneer Creek prospect ARDF number AN094.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Lower to Middle Jurassic
