Glacier Mine

The Glacier Mine is a silver and gold mine located in Conejos county, Colorado at an elevation of 9,879 feet.

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.

Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Deposit): MINE LIES IN AXELL DISTRICT AND DEVELOPS N TO NW-TRENDING ARCUATE FAULT THAT INTERSECTS THE GENERALLY N 55 E-TRENDING CALIFORNIA GULCH (MAJOR DAWN) FAULT ABOUT 0.45 MILE SOUTH OF MINE (AS MAPPED BY BIRD, 1973). HOST FAULT APPEARS TO BE PART OF BIRD'S NW SYSTEM OF FAULTS AND FRACTURES REFLECTING NW TREND OF PLATORO FAULT ZONE WITHIN CORNWALL RESURGENT BLOCK. SOUTH PART OF FAULT AT INTERSECTION WITH CALIFORNIA GULCH FAULT HAS STRONG NORTHERLY COMPONENT CHARACTERISTIC OF THE RESURGENT RADIAL FAULTS. AS CALIFORNIA GULCH FAULT IS MAJOR SE-BOUNDING FAULT OF CORNWALL BLOCK, IT IS PROBABLY DEEP ENOUGH TO HAVE TAPPED UNDERLYING MAGMA CHAMBER, THUS PROVIDING CONDUIT FOR MINERALIZING SOLUTIONS. SOUTH PART OF GLACIER HOST FAULT MAY HAVE BEEN MINERALIZED THROUGH ITS INTERSECTION WITH CALIFORNIA GULCH FAULT.

Comment (Workings): TWO TUNNELS DRIVEN GENERALLY SOUTHWARD

Comment (Location): CLAIMS LIE IN SEC. 25 ON SE-PROJECTING RIDGE OF MAMMOTH MTN SOUTH OF CONEJOS RIVER. ELEV AND LAT-LONG GIVEN ARE FOR LOWEST TUNNEL PORTAL IN NE SW SEC. 24 (SECTIONS PROJECTED INTO UNSURVEYED AREA). ; INFO FROM LAND.ST :1975

Comment (Production): PARTIAL PRODUCTION RECORD. NO PRODUCTION REPORTED FOR 1916-1917, 1919-1920. NO REPORTS PRIOR TO 1916 OR AFTER 1920.

Comment (Commodity): ORE MINERALS LISTED ABOVE ARE REPORTED FROM MAMMOTH-REVENUE MINE, AND ALTHOUGH NOT ALL ARE SPECIFICALLY NOTED AT OTHER MINES IN DISTRICT, THEY ARE GENERALLY APPLICABLE TO THEM (BIRD, 1973). ARSENOPYRITE REPORTED BY PATTON (1917) CITED FOR ENTIRE DISTRICT. PETZITE (TELLURIDE) REPORTED BY PATTON IN GILMORE AND PLATORO DISTRICTS WAS PROBABLY MISIDENTIFIED SULFIDE (BIRD, 1973). MINOR PRODUCTION OF CU AND PB UNCERTAIN DUE TO LACK OF OLDER PRODUCTION RECORDS.
