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 (Location): ON WEST INDIAN CREEK ON BLANCA TRINCHERA RANCH, UNSURVEYED SANGRE DE CRISTO LAND GRANT. LAT-LONG GIVEN IS FOR SITE APPROXIMATED FROM NELSON-MOORE AND OTHERS' (1978) PLATE 11.
Comment (Development): ONE PROSPECT PIT, SEVERAL SHALLOW TRENCHES. NINE HOLES DRILLED, TWO SHOW ANOMALOUS RADIOACTIVITY.
Comment (Deposit): NELSON-MOORE AND OTHERS (1978) REPORT MINERALIZATION IN CARBONACEOUS CONGLOMERATIC SANDSTONE IN SANGRE DE CRISTO FM, BUT JOHNSON'S MAP SHOWS MINTURN FM.
Comment (Deposit): A.B. Wilson attempted to check location against Google Earth. There is disturbed ground close to location given in original MRDS record D006701. Location given in MAS record 0080230007 is 10 km farther north. Using driving directions given in Nelson-Moore and others, p. 114, would not arrive at that location. Nor would they arrive at the selected location, probably because there are many newer roads.
Comment (Deposit): ABWilson recommends merged information from record 10166884 into this record 10011645 and deleted the former.
