The Ober Creek Placer is a gold and ree 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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property.

Comment (Deposit): MAINLY OF MINERALOGIC INTEREST; AU CONTENT AND RADIOACTIVITY TOO SLIGHT TO BE OF MUCH ECONOMIC SIGNIFICANCE ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Location): LOCATION APPROXIMATED FROM USGS OFR 79-238, FIG. 3, LOC. 2 LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): PROSPECTING AND POSSIBLY A LITTLE MINING IN EARLY 1900'S; PLACERS DISCOVERED TO BE SLIGHTLY RADIOACTIVE IN 1946 DUE TO THE PRESENCE OF MONAZITE
