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): EARLY AND MOST VOLUMINOUS PRODUCTION CAME FROM A 10 INCH WIDE VEIN OF OXIDIZED PB-AG ORE STRIKING NORTHEAST-SOUTHWEST AND DIPPING NORTHWEST IN QUARTZITE. MINOR MINERALIZATION PRESENT IN FRACTURES NEAR THE FLAGSTAFF MOUNTAIN STOCK
Comment (Location): INFO FROM LAND.ST :1983
Comment (Production): TOTAL PRODUCTION UNKNOWN, BUT MINE WAS ACTIVE NEARLY CONTINUOUSLY FROM 1871 TO 1881
Comment (Development): WAS THE FIRST PRODUCER FROM THE PARK CITY DISTRICT AND SECOND DISCOVERY. LAST RECORDED PRODUCTION IN 1881. INACTIVE WELL BEFORE 1912
Comment (Workings): EARLY DEVELOPMENT COMPRISED OF AN INCLINE SUNK ON EXPOSED, OXIDIZED FISSURE ORE TO A DEPTH OF 400 FT. A SIMILAR INCLINE AND SHAFT WERE SUNK NEARBY.
