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): GOLD BEARING DEPOSITS ARE ALMOST ENTIRELY IN THE IMMEDIATE BED OF THE STREAM. THE AURIFEROUS GRAVELS ARE 2-6 FEET DEEP AND HAVE AN AVERAGE WIDTH OF ABOUT 50 FEET.
Comment (Location): USGS MF-458, LOC. 10. PLACER MINE AND TAILINGS MARKED ON HUGHES (A-2). LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Geology): PLACER AREA UNDERLAIN BY PLUTONIC ROCKS. ; MAJOR.UNITS: BEDROCK THROUGHOUT THE AREA OF PROFITABLE PLACER GROUND IS GRANITE.
Comment (Development): GOLD DISCOVERED BY NATIVE IN 1909. J.C. FELIX STRUCK PAY DIRT IN THE SUMMER OF 1910. FIRST MINING IN DISTRICT IN SUMMER, 1911. PLACER MINING FROM 1911 TO AS RECENTLY AS 1965. LARGE-SCALE MINING CEASED IN 1961.
Comment (Workings): AT ONE PLACE THE PAY STREAK WAS UNDER THE EAST BANK OF THE STREAM FOR A SHORT DISTANCE, BUT THE DEPOSIT IS ON A LEVEL WITH THE STREAM AND DOES NOT INDICATE A TRUE BENCH DEPOSIT.
Comment (Deposit): STREAM GRADIENT APPROXIMATELY 100 FEET PER MILE. THE BOULDERS THAT MAKE UP MOST OF THE DEPOSITS ARE A HINDERANCE TO ECONOMIC MINING. THERE MAY HAVE BEEN MINING ALONG SNYDER CR., ON UNMARKED HEADWATER TRIBUTARY. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Comment (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.
