Geochemical survey of the Cohutta Wilderness and the Hemp Top Roadless Area, northern Georgia and southeastern Tennessee

The contiguous Cohutta Wilderness and Hemp Top Roadless Area are in the western part of the Blue Ridge physiographic province of northern Georgia and southeastern Tennessee (fig. 1). All of the study area is in Georgia except an irregular strip of land about 1 mi at its widest on the northern end of the Cohutta Wilderness in Tennessee. The area of the Cohutta Wilderness is 34,650 acres; that of the Hemp Top Roadless Area is 2,800 acres. The areas are in rugged mountainous terrain- a strongly dissected upland ranging in altitude from about 980 to 4,200 ft above sea level. Local altitude differences of 1,450-2,000 ft and slopes steeper than 25° are common. The north end of the Cohutta Wilderness is about 6 mi south of the Ocoee River gorge, 10 mi west-southwest of the major copper-and sulfur-mining district at Ducktown, Tenn., and approximately 22 mi southeast of Cleveland, Tenn., in Bradley County, west of the area shown in figure 1. The eastern, central, and northwestern parts of the wilderness are drained by Jacks River and it tributaries; the southwestern part, by the Conasauga River and its tributaries; and the Hemp Top Roadless Area, by Tumbling Creek and some of its western tributaries. All drainage ultimately goes to the Ocoee River and from these into the Hiwassee River.

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 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.
