The Ellicot Rock Wilderness comprises 3,332 acres in parts of Sumter, Nantahala and Chattahoochee National Forests. The Ellicott Rock Extension would expand wilderness boundaries in these national forests by 5,600 acres. The Ellicott Rock Extension, 5,512 acres and the Persimmon Mountain Area, 6,678 acres, are both in Sumter National Forest.

The Gee Creek Wilderness comprises 2,493 acres (nearly 4 square miles) in the Cherokee National Forest, Polk and Monroe Counties, Tennessee, about 4 miles (6 km) southeast of Etowah, Tenn., and about 20 miles northeast of Cleveland, Tenn. All of the surface in the wilderness is in U.S. Government ownership; mineral rights on nearly half of the land remain in private ownership. The study area is in the Blue Ridge physiographic province. The major rock types in the wilderness area consist of sandstone, shale, and conglomerate of the Chilhowee Group of Cambrian and Cambrian(?) age. Faulting appears to have controlled the location of minor subeconomic iron deposits, but no potential mineral resources were detected by the present survey. Shales, useful for brick or lightweight aggregate, and sandstone, useful for crushed stone or sand, have little economic interest because these rock types are common throughout the region and are found closer to potential markets. The possibility of natural gas occurring in untested rocks structurally beneath the Chilhowee strata cannot be discounted. No potential was found for any other mineral resource.

The james River Face Wilderness comprises 8,800 acres in the Jefferson National Forest and occupies parts of Bedford and Rockbridge Counties, west-central Virginia. It is about 2 mi southeast of Natural Bridge Station and 0.5 mi south of Glasgow (fig. 1). Access is provided by U.S. Route 501, State Route 130, and the Blue Ridge Parkway. Interior access is provided by the Appalachian Trail, other marked foot trails and a graded bridle path. The area, on the crest of the Blue Ridge Mountains, is drained by small tributaries of the James River. Altitudes range from 600 ft where U.S. Route 501 crosses the James River to 3,073 ft on Highcock Knob.
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 to extend into the study area, and geochemical data derived from samples of rock, soil, and alluvium do not reveal any anomalously high concentrations of trace elements that could be representative of hidden mineral deposits. Sedimentary rocks underlying the metamorphic rocks exposed at the surface have an unknown potential for hydrocarbons in the form of natural gas. No reasonable estimate of the potential can be made until some test drilling is done in the area.
