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 (Development): FROST WEDGING OF THE RHYOLITE HAS PRODUCED A LARGE ACCUMULATION OF TALUS.

Comment (Workings): INCLINED SHAFT, VERTICAL SHAFT, ADIT, SHALLOW PITS AND SHAFTS . SEVERAL FT OF WORKINGS HAVE BEEN EXTENED FROM THE SHAFT ON THE 200, 300, AND 400 FT LEVELS.

Comment (Geology): GEOL.DESC: SULFIDES, HEMATITE.

Comment (Location): NEAR CONTINENTAL DIVIDE. ; INFO FROM LAND.ST :(1954)

Comment (Production): TERTIARY RHYOLITE HAS BEEN QUARRIED W OF THE JOSEPHINE MINE. IT IS USED FOR DECORATIVE STONE.

Comment (Deposit): VEINS DIP VARIES FROM 55-70 N . THE VEIN IS CONCEALED AT THE SURFACE BY TERTIARY RHYOLITES. PRONOUNCED FLOW BANDING PRODUCES A PLEASING TEXTURE- AND A FRESH COLOR RANGES FROM PALE RED TO THE DOMINANT YELLOW GRAY. WEATHERED COLOR IS DARKER.
