Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Deposit): KRASOWSKI'S MAP SHOWS VEIN TO LIE IN FAULT CUTTING PRECAMBRIAN GRANITE AND TRENDING GENERALLY N 35 TO 45 E, LYING SUBPARALLEL TO AND SE OF FAULTS ON WHICH CLEVELAND MINE DEVELOPED. WOOLSEY NOTED THAT GRANITE WAS HEAVILY PYRITIZED NEAR THE THREE OR MORE QUARTZ VEINS AGGREGATING 1.5 FT IN WIDTH. ORE REPORTEDLY WAS CHALCOPYRITE AND PYRITE MIXED WITH QUARTZ AND CALCITE.
Comment (Workings): WOOLSEY (1907) DESCRIBES WORKINGS AS 50-FT-DEEP SHAFT WITH SHORT SW DRIFT FROM BOTTOM; TUNNEL OF UNKNOWN EXTENT.
Comment (Location): WOOLSEY (1907 GIVES LOCATION AS MOUTH OF CLEVELAND GULCH ADJACENT TO WHITECROSS. ELEV AND LAT-LONG GIVEN ARE FOR SHAFT ON HILLSIDE 0.17 MILE NNW OF WHITECROSS, AS PLOTTED BY KRASOWSKI (1976) (UNSURVEYED SECTION). ; INFO FROM LAND.ST :1977
