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 (Deposit): DOM. REF. INCLUDE THIS WITH PLACER COUNTY MINES, BUT DESCRIPTION OF LOCATION IN 15TH REPT. DOM, SAYING LOC. WEST OF GREENHORN CREEK WOULD PLACE LOCATION IN NEVADA COUNTY; HOWEVER, THIS REFERENCE PROBABLY DERIVED INFORMATION FROM USGS FOLIO 66, P. 7, AND EC. GEOL. SHEET WHICH SHOW A COPPER PROSPECT EAST OF THE GREENHORN CREEK, SOUTH OF POORMAN CREEK, AND ON OR SLIGHTLY WEST OF THE ROAD. THE UNIDENTIFIED SHAFT SHOWN IN NE1/4 NW1/4 OF SEC. 14 ON TOPO MAP MAY BE THIS PROSPECT?
