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): MASSIVE SANDSTONE - 30 FT IN THICKNESS
Comment (Deposit): "Massive sandstone, averaging about 30 ft in thickness, is exposed over a width of approximately 400 ft and extends along the strike for a distance of approximately one mile. This bed, which strikes N50W, and dips 23SW, crops out as a hogback. The rock, as exposed, is a yellowish-gray fine grained, cross-bedded soft and poorly cemented quartz sandstone." (Bull 50, p. 78)
Comment (Deposit): A glass sand deposit.
