Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comment (Location): DISTRICT LOCATED ALONG CEBOLLA CREEK BETWEEN WHITE EARTH DISTRICT (TO NORTH) AND GUNNISON-HINSDALE COUNTY LINE (ON SOUTH). INCLUDES LOWER PARTS OF RUDOLPH GULCH, MUD GULCH, SWINEHART GULCH, CRYSTAL CREEK, AND WATER GULCH. PROMINENT LANDMARKS INCLUDE MILLER HILL, SWINEHART RIDGE, POLEPATCH HILL, FISH CANYON RIDGE, AND HIDDEN LAKE. DISTRICT ACCESSIBLE VIA COLORADO RTE 149 FROM U.S. RTE 50 AND BLUE MESA RESERVOIRSW TO POWDERHORN AND VIA ROAD SOUTH FROM COLORADO RTE 149 THROUGH POWDERHORN AND UP CEBOLLA CREEK; VIA ROAD NE FROM LAKE CITY AND LAKE SAN CRISTOBAL, OVER SLUMGULLION PASS, AND DOWN CEBOLLA CREEK THROUGH CATHEDRAL; VIA ROAD FROM COLORADO RTE 114 AND COCHETOPA CREEK SW UP LOS PINOS CREEK, OVER LOS PINOS PASS TO CEBOLLA CREEK AND CATHEDRAL. SECTIONS LISTED INCLUDE THOSE CONTAINING PATENTED CLAIMS AND THOSE COVERING PROSPECTED AREA OF METAGABBRO.

Comment (Workings): PROPERTIES EXPLORED BY SURFACE PROSPECTS AND BY SEVERAL SHAFTS OF UNKNOWN DEPTH.

Comment (Development): HISTORY OF DISTRICT LARGELY UNKNOWN. CASHIER AND RAINBOW CLAIMS SURVEYED IN 1901 AND PATENTED IN 1903 BY HENRY RUDOLPH.
Comment (Deposit): LARGE BODY OF METAGABBRO COVERS ABOUT 4 SQ MI; FOLIATION TRENDS VARIABLE NE-SW TO NORTH-SOUTH, MOSTLY VERTICAL DIPS. METAGABBRO CONTAINS SEVERAL TABULAR BODIES OF DIORITE-GABBRO ROCK OF DIFFERENT COMPOSITION AND TEXTURE THAN METAGABBRO. LOCALLY INTRUDING NW AND SE MARGINS OF METAGABBRO ARE TWO LINEAR BODIES OF GNEISSIC QUARTZ DIORITE 500 TO 1500 FT WIDE IN PLAN. BEYOND QUARTZ DIORITE, POWDERHORN GRANITE INTRUDES, WITH SEVERAL SMALL BODIES WITHIN METAGABBRO. ON WEST, FAULTS DISPLACE METAGABBRO AGAINST GRANITE. AREAS EAST AND SW OF METAGABBRO COVERED BY OLIGOCENE TUFFS. VEINS, QUARTZ VEINS, AND TRACHYTE DIKES INTRUDE METAGABRRO GENERALLY ALONG FOLIATION, BUT SOME CUT FOLIATION AT HIGH ANGLES. DIP OF VEINS MEASURED AT 44 TO 85 DEG. MOST VEINS HAVE BEEN PROSPECTED. ORIGIN OF MINERALIZATION UNCERTAIN BUT COULD BE (1) REMOBILIZATION OF SUBMARINE MASSIVE SULFIDES DEPOSITED IN GABBRO SEQUENCE, OR (2) LATE-STAGE HYDROTHERMAL VEIN DEPOSITS ASSOCIATED WITH EMPLACEMENT OF LATE PRECAMBRIAN TO
