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.

Comments
Comment (Deposit): "A QUARTZ-SPECULARite VEIN TRENDS North FOR 1 MILE, DISAPPEARS FOR 1 MILE, THEN APPEARS AGAIN. The vein cuts granite." (Bull. 50, p. 118).
Comment (Identification): This is the first listed hematite deposit in Natrona County in Bull. 50. The second entry immediately below on p. 118 is also called the Koch deposit. To make them distinct, the latter is now called the Koch hematite prospect on Casper Mountain (see the original reference in Bull. 50).
