Satelite View

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

Comments
Comment (Deposit): MANGANESE OXIDES DERIVED FROM WEATHERING OF THE CHERT OCCUR ONLY IN THE UPPERMOST PORTIONS OF THE FORMATION, USUALLY 30 FEET FROM THE SURFACE. BELOW THAT, MANGANESE OCCURS AS RHODONITE AND BEMENTITE.
Comment (Geology): SEDIMENTS ALSO IRREGULAR BODIES OF JASPER
