Mineral resource potential map of Hercules Glades Wilderness, Taney County, Missouri Mineral resource potential map of Hercules Glades Wilderness, Taney County, Missouri
Under the provisions of the Wilderness Act (Public Law 88-577, Sept. 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe" when the act was passed were incorporated into the...

Mineral resource potential map of the Bighorn Mountains Wilderness Study Area (CDCA-217), San Bernardino County, California Mineral resource potential map of the Bighorn Mountains Wilderness Study Area (CDCA-217), San Bernardino County, California
Geological, geochemical, and geophysical evidence, together with a review of historical mining and prospecting activities, suggests that most of the Bighorn Mountains Wilderness Study Area has low potential for the discovery of all types of mineral and energy resources-including precious and base metals, building stone and aggregate, fossil fuels, radioactive-mineral resources, and...
Mineral resource potential map of the Clear Lake Roadless Area, Leon County, Florida Mineral resource potential map of the Clear Lake Roadless Area, Leon County, Florida
The only mineral material that has been produced within the Clear Lake Roadless Area is clayey sand used as fill for highway construction and for stabilizing Forest Service roads. Fuller's earth, common clay, and sand and gravel presently are produced in Leon County and in nearby counties, and limestone and peat have been produced in the past. However, no commercial deposits of these...
Mineral resource potential map of the Cohutta Wilderness and the Hemp Top Roadless Area, northern Georgia and southeastern Tennessee Mineral resource potential map of the Cohutta Wilderness and the Hemp Top Roadless Area, northern Georgia and southeastern Tennessee
The Cohutta Wilderness and the Hemp Top Roadless Area have minor occurrences of metallic minerals, but no known resource potential for such minerals in the forseeable future, judging by available data, and only a very minor potential for stone for aggregate, road construction, and similar nondimension use. The rocks of the Ducktown massive sulfide district to the northeast do not appear...
Mineral resource potential map of the Gila-San Francisco Wilderness Study Area, Graham and Greenlee counties, Arizona Mineral resource potential map of the Gila-San Francisco Wilderness Study Area, Graham and Greenlee counties, Arizona
The mineral resource potential of the Gila-San Francisco Wilderness Study Area (AZ-040-022/023/024) is low (fig. 2). Although favorable geologic environments for placer gold deposits and manganese vein deposits are present in the study area, the probability of discovering economically exploitable deposits of these metals is low, and not encouraging. Even more speculative is the study...
