Satelite View

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

Comments
Comment (Deposit): "A pit in the NE4 sec. 30, T32N, R79W, 11 mi from Casper, in the Casper limestone revealed pyrolusite in patches and pockets. The Casper Formation dips 20 to 25 degrees SE. More work is necessary to determine the extent of the deposit." (Bull. 50, p. 130).
