Mine Info

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.

Comment (Workings): AREA CONSISTS OF 5 ADITS (TOTALING 1, 397 FT) & 13 PITS & TRENCHES NUMEROUS PUBLICATIONS SINCE 1914 HAVE PLACED THE WORKINGS AT ABOUT 9,000 FT TO 10,000 FT ELEV ALONG THE CREST OF THE CONTINENTAL DIVIDE, & THE MINERAL SURVEY NOTES OF 1902 ALSO SHOW THE CLAIMS TO BE ALONG THE CREST, HOWEVER, THE PATENTED CLAIM BOUNDARIES SHOWN ON CURRENT BLM RECORDS & FOREST SERVICE MAPS ARE PLACED 800 TO 1,200 FT BELOW THE CREST, PROBABLY IN ERROR
