The Flat Creek Placer 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.

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. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Deposit): Discovery Year: 1913-1914
Comment (Deposit): GOLD ON OR IN UPPER 6 IN. OF BEDROCK OR ON CLAY FALSE BEDROCK A SHORT DISTANCE ABOVE THE TRUE BEDROCK. GOLD IN NARROW, IRREGULAR PATCHES AND STREAKS OVER A WIDTH OF AS MUCH AS 1,000 FT. ONE SHAFT SHOWED A DEPTH OF 55 FT. TO BEDROCK, OF WHICH THE UPPER 37 FEET WAS MUCK AND THE LOWER 18 FEET GRAVEL; ALLUVIUM SOLIDLY FROZEN. ELSEWHERE, 2-30 FT. OF GRAVEL BENEATH 40-50 FEET OF MUCK. FURTHEST DOWNSTREAM PLACERS CONTAIN RUSTY AND OXIDIZED GRAVEL; THOUGHT TO REPRESENT AN OLD CHANNEL OF TIMBER CREEK.
