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

Comments
Comment (Geology): GEOLOGIC MAP INDICATES AREA IS UNDERLAIN BY EITHER SWAUK FORMATION OR TONALITE OF SILVER CREEK DEPENDING ON EXACT LOCATION OF DEPOSIT. GRANODIORITE MAY BE AN AREA TOO SMALL TO SHOW AT MAP SCALE OR MAY BE PART OF TONALITE INTRUSION
Comment (Deposit): NARROW MINERALIZED FRACTURE ZONE WITH SPORADICALLY DISTRIBUTED ORE SHOOTS 3-8 IN. WIDE. THE TYPE OF DEPOSIT IS UNKNOWN
Comment (Location): NORTH OF BEAR CLAIMS ON SOUTH SLOPE OF MINERAL MOUNTAIN ON WEST SIDE OF WEST FORK SILVER CREEK. BROUGHTON GIVES ALTERNATIVE LOCATION OF SE/4 SEC. 31, T. 29 N., R. 11 E.
