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 (Development): ONE OF STATE'S LARGEST PLACERS IN EARLY 1900'S. MINING SEASON IS 7 MONTHS/YR
Comment (Geology): WORKINGS IN TERTIARY CONGLOMERATE MINOR IN COMPARISON TO PLEISTOCENE GRAVELS. BEDROCK VARIES - TERTIARY CONGLOMGERATE, SERPENTINE; HORSETOWN(?) SANDSTONE ; GEOL.DESC: BEDROCK VARIES - TERT. CONG., SERP; HORSETOWN (?) SANDSTONE
Comment (Location): ON CARROLL SLOUGH AND FRENCH FLAT. LOCATION GIVEN IS TAILINGS NORTH OF ESTERLY LAKES
Comment (Commodity): PT IS FLATTENED SCALES WITH ROUNDED CORNERS - TINY GRAINS TO >2 MM. MOST OF GOLD IS ANGULAR. PLATINUM METALS ARE MOSTLY PT WITH RU, SOME IR, OS, SLIGHT PD, RH
Comment (Production): FOR MANY YEARS THIS WAS THE MOST PRODUCTIVE AU-PT PLACER IN OREGON
Comment (Deposit): AVERAGE THICKNESS 18 FT. AU, PT CONCENTRATED NEAR BEDROCK BUT SOME GOLD THROUGHOUT FORMATION
Comment (Workings): OVER 30 ACRES HYDRAULICKED. SEVERAL BIG PITS
Comment (Deposit): SEE ALSO: MRDS M013263.
Comment (Reserve-Resource): LARGE AREAS CONTAINING GOLD ARE UNTOUCHED. 1921 ESTIMATE: GRAVELS AVERAGED $0.18 IN RESERVES
