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 (Location): USGS MF-393, LOC. 52. MINE MARKED ON EAGLE (A-2) AT HEAD OF LOST CHICKEN CR. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
Comment (Development): AURIFEROUS GRAVEL FOUND ON BENCH ON LOST CHICKEN HILL 275 FT. ABOVE CREEK IN 1901. BENCH PLACER FIRST WORKED BY DRIFTING. WHEN MINED OUT, THE PAYSTREAK WAS FOLLOWED DOWN THE WEST SIDE OF THE VALLEY OF LOST CHICKEN CREEK. MINING IN LATER YEARS CONFINED TO VALLEY, MAINLY BY HYDRAULIC METHODS. INTERMITTANT MINING.
Comment (Deposit): GOLD IN LOWER PART OF GRAVEL AND ON BEDROCK. GOLD DISCOVERED AT A DEPTH OF 33 FT. IN BENCH GRAVEL. MOST OF GOLD FOUND ON HIGH BENCHES ON THE WEST SIDE OF CREEK.
Comment (Workings): DRIFTS RAN FROM SHAFTS 33 TO 55 FT. DEEP.
Comment (Geology): BEDROCK SURFACE UNEVEN AND HARD TO CLEAN. ; MAJOR.UNITS: BEDROCK IS DECOMPOSED GRANITIC ROCKS, SAID TO BE QUARTZ DIORITE CUT BY A BASALT DIKE. ; REG.COM: GOLD THOUGHT TO BE DERIVED LOCALLY FROM GRANITIC INTRUSIVE ROCKS.
Comment (Deposit): STREAM GRADIENT ABOUT 300 FEET PER MILE ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
