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): WEST OF AND ADJACENT TO NEW RAMBLER MINE. IN MEDICINE BOW NATIONAL FOREST
Comment (Production): NO PRODUCTION FIGURES GIVEN, PRESUMED SMALL
Comment (Deposit): VEINS IN GOUGE ZONES; UNPUBLISHED MODEL NAME: NEW RAMBLER CU-AU-PGE.
Comment (Workings): SHAFTS. INTERSECTED ORE AT 120 FT
Comment (Geology): GEOLOGY IS SIMILAR TO THAT OF NEW RAMBLER MINE TO EAST
Comment (Deposit): RECORD W032393 HAS BEEN MERGED AND DELETED. MAS 0560010110 has also been merged and deleted.
Comment (Location): Visited Aug. 3, 2010, by Wilson and Heran (USGS). Location by GPS agrees with locations in Bull. 68. It's hard to believe this was ever a very large mine--currently it is little more than a small depression in woods among summer cabins.
