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): LOCATED ON SHAFT
Comment (Workings): MOST OF WORKINGS NOW INACCESSIBLE
Comment (Geology): FRANCISCAN SEDIMENTS AND SERPENTINE CONSTITUTE THE MAJOR ROCKS OF THE DISTRICT WHILE KNOXVILLE STRATA OCCUR E OF THE ORE DISTRICT. THESE ARE OVERLAIN BY PLEIOCENE - PLEISTOCENE SONOMA VOLCANICS WHICH ARE RHYOLITIC TUFFS AND AGGLOMERATES OF BASALT ANDESITE AND RHYOLITE. PRIOR TO THE UPPER PLEIOCENE THE ROCKS WERE FOLDED AND FAULTED GIVING MAJOR NW STRUCTURAL TRENDS. MANY OF THE MERCURY DEPOSITS OCCUR ALONG THE FLANKS OF A MAJOR ANTICLINE. THE SEDIMENTS HAVE BEEN HYDROTHERMALLY BLEACHED AND KAOLINIZED WHILE THE SERPENTINE HAS UNDERGONE SILICA - CARBONATION. ORE BODIES INCLUDE THOSE IN SILICA CARBONATE ROCK (MOST ABUNDANT), BODIES ALONG FAULTS IN FRANCISCAN SANDSTONE, OCCURRENCES ALONG CONTACTS WITH BASALT DIKES, AND BODIES IN BRECCIATED CHERT.
