About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
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): Original record stated (misplaced in the references section) "U-BEARING CACO3 VEINS CUT PENNSYLVANIAN TENSLEEP FM." MINOBRAS, p. A-7, states "Carnotite aggregates in claystone-sandstone, North Park Form(?) Tertiary"
Comment (Deposit): "LOVE, J. D., U.S.G.S." was in the reference field. Unable to determine if Dr. Love was source of information or discoverer or something else.
Comment (Deposit): Unable to determine if two Chimney Rock records (see also 10081044) are the same. Cited sources place them in different section, township, ranges, although within a couple miles.
