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): MUILENBURG (1919) CITES GENERAL LOCATION OF CLAIM AS ABOUT 5 MILES SE OF NATURITA NEAR TOP OF DIVIDE (NATURAL RIDGE) BETWEEN SAN MUGUEL RIVER AND DRY CREEK DRAINAGE. DESCRIPTION OF EXPOSURE ON RESISTANT RIM ABOVE STREAM VALLEY SUGGESTS POSSIBLE LOCATION ALONG LONG DRAW OR BROAD CANYON. ELEV AND LAT-LONG GIVEN ARE FOR COMMON SECTION CORNER ALONG DRAWNEAR DEEP EXOSURE ON NE SIDE OF DIVIDE. ; INFO FROM LAND.ST :1975
Comment (Deposit): TOP OF NATURITA RIDGE CORRESPONDS TO NW-SE TREND OF DRY CREEK ANTICLINE AND HAMILTON CREEK ANTICLINE, THE SE EXTENSIONS OF PARADOX VALLEY ANTICLINE. ROCKS EXPOSED ACROSS CREST OF ANTICLINES ARE LOWER CRETACEOUS BURRO CANYON FM AND DAKOTA SANDSTONE. MUILENBURG (1919) DESCRIBES OCCURENCE AS THIN SEAM QUARTER OF INCH TO FOUR INCHES THICK SEPARATING TWO BEDS OF SANDSTONE OR REPRESENTING PARTING IN SANDSTONE. SEVERAL OTHER SEAMS LIE ABOVE AND BELOW, SEPARATING THIN BEDS OF SANDSTONE. WEIR ANDPUFFETT (1981) STUDIED LISBON VALLEY AREA MN DEPOSITS AND FOUND COMMON OCCURRENCE IN NONCARBONACEOUS SANDSTONE AND SUGGESTED THAT THEIR ASSOCIATION WITH LISBON VALLEY FAULT SYSTEM MAY HAVE REPRESENTED LATE-STAGE LOW-TEMPERATURE MINERALIZATION IN AREA. IT IS CONCEIVABLE THAT MCNUTT DEPOSIT COULD HAVE SIMILAR ORIGIN WITH RESPECT TO STRUCTURE ALONG PARADOX VALLEY ANTICLINE.
