Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

FOLIATION OF BLACK CANYON SCHIST AND GNEISS COUNTRY ROCK TRENDS GENERALLY N 30 TO 35 W, 80 TO 90 NE. PROSPECT LIES ON PRINCIPAL FAULT TRENDING N J0 TO 50 W. PEGMATITES IN VICINITY TREND N 60 W AND N 80 E. GRANITE DIKES IN VICINITY TREND N 32 W, N 57 W, AND N 70 E.
Comment (Workings): ONE SURFACE PROSPECT PIT
Comment (Geology): OTHER MINERALS LISTED ABOVE ARE GENERAL OCCURRENCES REPORTED FOR TH VEINS IN AREA; ALL MAY NOT NECESSARILY OCCUR AT THIS SITE.
