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): LOWER PART OF GRANITE RIDGE ON WEST SIDE OF NORTHERN NIGHTINGALE RANGE, ABOUT 1000 YARDS FROM RAGGED TOP-GERLACH ROAD ; INFO FROM LAND.ST :(1972)
Comment (Deposit): A YELLOW POWDERY URANIUM MINERAL OCCURS IN ASSOCIATION WITH A HIGHLY ALTERED PEGMATITE DIKE. VERTICAL VEINLETS OF QUARTZ WITH BLACK TOURMALINE INTRUDED ALONG A N 85 E STRIKE IN ROTTEN QUARTZ MONZONITE. MOST STRUCTURE IN QUARTZ MONZONITE IS OBSCURED BY WEATHERING AND ALTERATION. THE URANIUM IS ASSOCIATED WITH THE VEINS, BUT IS IN THE ALTERED QUARTZ-MONZONITE.
