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.

Comment (Geology): TOWARD FACE OF DRIFT, HORIZONTAL GROOVING INDICATES CONSIDERABLE LATERAL MOVEMENT ALONG SHEAR ZONE; GARDNER CANYON DIKE SWARM CONSISTS OF RHYOLITE PORPHYRY DIKES, MOST OF WHICH TREND N50-60E AND DIP NEARLY VERTICALLY

Comment (Development): OTHER PAST OPERATORS INCLUDE: O. A. REID (1936), PARKER AND REED (1931), RICHARDSON (1930), MCCUTCHEN AND HOGAN (1913-1914); DEVELOPED IN MID-1890'S AND PRODUCED INTERMITTENTLY THROUGH 1937; CONNECTICUT GROUP COMPRISES 12 CLAIMS
