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.

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.

Comments

Comment (Deposit): THIS RECORD HAS BEEN MERGED WITH M242821, WHICH HAS BEEN DELETED. THESE PROSPECTS ARE OFTEN CONFUSED WITH SAGE HEN MINE (OR HILLTOP MINE), WHICH ARE LOCATED ABOVE THE PROSPECTS ON RIDGE CREST. UTM COORDINATES ARE FROM STAGER AND TINGLEY (1988).

Comment (Deposit): SCATTERED TACTITE OUTCROPS WITH SCHEELITE CRYSTALS UP TO 2 INCHES LONG ALONG REMNANT BEDDING PLANES AND CRACKS IN THE TACTITE. ROOF PENDANTS OF LIMESTONE IN THE GRANITIC INTRUSIVE UP TO HUNDEREDS OF FEET LONG, CUT BY MONZONITE DIKES. PARTS OF THE MONZONITE ARE PROMINENTLY SHEETED IN PLATES 2-6 FT THICK.

Comment (Workings): PROSPECTS

Comment (Location): ON BOTH SIDES OF WILLOW GULCH WHICH DIVIDES THE LAVA BEDS MOUNTAINS, UNLABELED ON TOPO SHEET; 3.5 MILES SOUTH OF SHEEP HEAD SPRING BELOW ELEPHANT HEAD ROCK. . INFO FROM LAND.ST :(1972)

Comment (Development): FIRST VISITED BY HESS AND LARSON IN 1917.

Comment (Geology): THE SCHEELITE-BEARING SKARN DEPOSITS ARE SMALL WITH BROWN GARNET AND EPIDOTE FORMING STREAKS 1 TO 12 INCHES WIDE IN POORLY EXPOSED PODS OF SEDIMENTARY ROCKS IN GRANITE. VERY LITTLE SCHEELITE IS VISIBLE. THE DEPOSITS OCCUR FROM THE BASE TO THE TOP OF THE RIDGE, AND FOR A DISTANCE OF ABOUT 2 MILES ALONG THE RIDGE.
