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.
Mine Description
Location: Altitude, about 8,530 it; 800 ft S. 62° E. of Illinois.
Geology: Shaft workings on vein that strikes N. 77° E. and dips 85° S.; open-cut and tunnel 100 ft farther south on vein that strikes N. 50° E. and dips 80° NW. (pI. 5). These upper workings are in granite, but a drift that enters below them from the Illinois Extension shaft is in schist.
