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

Comments
Comment (Location): UTM APPROX
Comment (Geology): GEOL.DESC: MANGANESE ASSOCIATED WITH MASSIVE METACHERT LENSES. DUSTY BLACK MANGANESE OXIDE OCCURS AS STAINS AND FINELY DISSEMINATED PARTICLES. LARGEST ORE BODY VARIES FROM 8 TO 12 FT. IN WIDTH AND CAN BE TRACED FOR OVER 100 FT. NO PRIMARY MINERALS ARE PRESENT, BUT ORE IS SIMILAR TO OXIDATION PRODUCT OF MANGANESE GARNET IN CALAVERAS COUNTY. METACHERT (QUARTZITE) IS VERY PURE WITH FEW LIMONITE AND SERICITE PARTICLES. ROCKS ON THIS PART OF HOG MOUNTAIN ARE QUARTZ SCHIST, QUARTZ-MICA SCHIST, AND QUARTZITE OF CALAVERAS FORMATION
