Comments
Comment (Development): FROM HEYL (1964): "ALTHOUGH THE AREA WAS PROSPECTED AS EARLY AS 1879, A REPORT IN 1881 THAT VERY RICH SILVER ORE HAD BEEN DISCOVERED LED TO A LARGE-SCALE MINERAL RUSH EARLY IN 1882, WHEN MORE THAT 2,000 MEN CAME TO THE AREA TO PROSPECT. THEY FOUNDED A TOWN CALLED CARBONATE, THE FIRST COUNTY SEAT OF GARFIELD COUNTY, BUT LOCATED ONLY SMALL DEPOSITS, WIDELY SCATTERED OVER THE PLATEAU; BY THE FOLLOWING WINTER MOST OF THEM HAD BECOME DISCOURAGED AND LEFT. SINCE THEN, PROSPECTING AND MINING HAVE BEEN ONLY SPORADIC...A FEW TONS OF OXIDIZED ZINC ORE ARE REPORTED TO HAVE BEEN PRODUCED, PROBABLY IN 1941 OR 1942, FROM THE DEFIANCE GROUP OF MINES AND PROSPECTS..."
Comment (Deposit): NO INDIVIDUAL RECORDS PREPARED FOR DISTRICT. MOST OF ABOVE DESCRIPTIONS COME FROM MAIN UNNAMED WORKINGS AT CARBONATE. OTHER NAMES LISTED BY HEYL (1964) BUT NOT DESCRIBED SUFFICIENTLY INCLUDE CANYON CREEK AND JOHNSON CREEK PROSPECTS NEAR CARBONATE, DEFIANCE OR FORT DEFIANCE MINE (SEC. 25, T 5 S, R 89 W), AND WINDY POINT (OR STRONG) MINE AND TRANSFER SPRINGS STAGE ROAD PROSPECTS PROBABLY LOCATED NEAR WINDY POINT (SEC. 12 AND 13, T 5 S, R.89 W AND SECS. 18 AND 19, T 5 S, R 88 W), ALTHO HEYL'S MAP SHOWS LOCATION CLOSER TO GLENWOOD SPRINGS AT APPROX. SEC. 30, T 5 S, R 89 W. ; INFO.SRC : 1 PUB LIT
Comment (Deposit): SOUTHERN FLANK OF WHITE RIVER UPLIFT CUT BY E-W AND WNW-ESE TRENDING NORTH-DIPPING DOLAN GULCH, GRIZZLY CREEK, AND SPRING CREEK REVERSE FAULTS, BETWEEN WHICH ARE NUMEROUS SUBPARALLEL AND NW-SE TRENDING NROMAL FAULTS WITH A FEW OF NE-SW TREND. FISSURE VEINS AND WEAK STOCKWORKS CUT LEADVILLE LIMESTONE AND CHAFFEE FM. AT CARBONATE, PRINCIPAL VEIN PARALLELS NORMAL FAULT STRIKING N 55 TO 65 E AND DIPPING 80 TO 90 SE. VEINS ARE LOCATED PERIPHERAL TO BASALTIC VOLCANIC NECK AND SCORIA CONE, LOCALLY METAMORPHOSING LEADVILLE LIMESTONE TO MARBLE. ORE NEARLY ALL OXIDIZED, LITTLE SULFIDES LEFT.
Comment (Workings): SHAFTS, ADITS, PITS, AND TRENCHES
Comment (Location): MAIN PART OF DISTRICT LIES NEAR CARBONATE TOWNSITE AT HEADS OF GRIZZLY, CANYON, AND JOHNSON CREEKS. ISOLATED DEPOSITS FOUND NORTH OF COLORADO RIVER NEAR SHOSHONE, AND 2 (?) TO ABOUT 5 MILES NORTH OF GLENWOOD SPRINGS IN WINDY POINT AREA NEAR HEADS OF MITCHELL, CASCADE, OASIS, AND EAST NO NAME CREEKS. ; INFO FROM LAND.ST :(1975)
