The Upper Ophir Creek 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 (Deposit): Model Name = Placer Au-PGE (Cox and Singer, 1986; model 39a)
Comment (Geology): Geologic Description = The Bendeleben A-4 topographic map shows placer mine workings over about 1,000 feet of the Ophir Creek just downstream from its confluence with Flat Creek. This may be the location referred to by Smith and Eakin (1911) as the bench at the head of the canyon that was being mined in 1903. This area is proximal to the Late Pleistocene terminal moraine complex of the Pargon River valley. The possible influence of outwash waters or sediments from this moraine complex on placer deposits of the Ophir Creek drainage is not known. The Ophir Creek (and Crooked Creek) placers were well developed, rich, and the product of more than one cycle of erosion and placer development. Perhaps drainage from the moraine complex did not flow down Ophir Creek.
Comment (Geology): Age = Quaternary
