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.

Comments
Comment (Geology): GEOL.DESC: 3 BRECCIATED ZONES 250 FT. APART ALONG FISSURES CEMENTED, IMPREGNATED, AND PARTLY REPLACED BY MANGANESE OXIDE. ORE IS ACCOMPANIED BY CALCITE, JASPER AND HEMATITE. FISSURES OCCUR IN RHYOLITE AND RHYOLITE BRECCIA. ZONES CEMENTED BY MANGANESE OXIDE HAVE A WIDTH OF 2 TO 3 FT., A LENGTH OF 30 TO 100 FT, AND MAY BE 20 FT. THICK. THE OXIDE IS PARTLY HARD, BOTRYOIDAL PSILOMELANE AND PARTLY SOFT BLACK OXIDE.
