Mineral resource potential map of the Fossil Ridge Wilderness Study Area, Gunnison County, Colorado
Ed DeWitt, R. J. Stoneman, J. R. Clark, S.E. Kluender
1985, Miscellaneous Field Studies Map 1629-A
Parts of the Fossil Ridge Wilderness Study Area have a high resource potential for gold and silver in small deposits, uranium in medium-size deposits, and high-calcium limestone in large deposits. Parts have a moderate to high potential for uranium, thorium, and light rare-earth elements in small- to medium-size deposits, a...
