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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments
Comment (Location): SECTION SUBDIVISIONS SW 1/4 NW 1/4 SW 1/4 SECTION 10
Comment (Deposit): URANIUM OCCURS IN THE STRUCTURE OF OPALINE SILICA IN FRACTURE FILLINGS IN TUFF. THE EXPOSED LENGTH OF ONE ZONE OF OPAL IS 70 FT LONG X 6 FT WIDE
Comment (Workings): WORKINGS CONSIST OF A SMALL OPEN CUT THAT IS 75 FT LONG X 40 FT WIDE, AND A SHALLOW SHAFT (15 FT DEEP)
Comment (Geology): THE OPAL IN FRACTURE FILLINGS IS GENERALLY ZONED, THE ZONING BEING DEFINED BY VARING SIZE OF FIBROUS CRYSTALLITES ORIENTED PERPENDICULAR TO THE WALLS OF THE VEINS ; GEOL.DESC: DEPOSITS ARE NUMEROUS STEEP-DIPPING SMALL VEINS AND URANIFEROUS OPAL.
Comment (Deposit): THE URANIFEROUS OPAL FLUORESES BRIGHT YELLOW-GREEN UNDER ULTRAVIOLET LIGHT, WHICH CAN BE USED TO DISTINGUISH IT FROM NON-URANIFEROUS OPAL IN THE DISTRICT ; INFO.SRC : 3 FIELD OBSERV
