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 (Location): MORE EXACT MERIDIAN LOCATION NW 1/4 SW 1/4 SE 1/4 SEC. 22, T 21S, R14E.
Comment (Geology): MINERALIZATION IS LARGELY CONFINED TO PALEOCHANNELS AND IS CLOSELY RELATED TO PLANT REMAINS, WHICH HAVE BEEN PARTIALLY OR WHOLLY REPLACED BY URANIUM AND/OR VANADIUM MINERALS
Comment (Reserve-Resource): MINE IS INACCESSIBLE AND RESERVES AND POTENTIAL RESERVES MAY BE GREATER THAN EXPECTED.
Comment (Development): L60 - ECONOMIC STUDY (1957), L70 - ECONOMIC STUDY (1975 - 76)
Comment (Deposit): DEPOSITS ARE ELONGATE IN DIRECTION OF PALEOCHANNELS
Comment (Workings): MINE IS REACHED BY A 305 FT. SHAFT. THE MINE IS PRESENTLY FLOODED (PREVIOUS OPERATIONS REQUIRED PUMPING).
