Satelite View

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

Comments
Comment (Commodity): RANDALL (1886) REPORTED BISMUTHINITE WITH BISMUTITE IN QUARTZ VEIN NEAR GUY HILL. ECKEL (1961) STATES THAT THE SITE IS PROBABLY AT THE CHRYSOBERYL LOCALITY, DESCRIBED BY HANLEY AND OTHERS AS "RAMSTETTER RANCH PROSPECT." ORIGINAL CRIB RECORD LISTS OCCURRENCE OF MO, BUT THIS WAS NOT CONFIRMED THROUGH LITERATURE.
