The U.S. Bureau of Mines conducted a field reconnaissance of Sipsey Wilderness in the fall of 1978 and of the roadless areas in the spring and summer of 1979. Mines, quarries, prospects, exposures, and drill sites in and near the study area were examined. Fifty-three samples were collected during the field work; sample localities are shown in figure 3. Analyses and preliminary test results for all limestone, clay and shale, sandstone, and coal samples were reported by Mory and others (1981). Mineral resource potential of the Sipsey Wilderness and additions is reported by Schweinfurth and others (1982). No mining activities are being conducted in the study area at present. Previous mining has been limited to small-scale production of limestone and coal. Two oil and gas test holes have been drilled inside the study area.
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. The act also directs that results of such surveys be made available to the public and be submitted to the Administration and the Congress. This report presents a part of the results of a mineral survey of the Otter Creek Wilderness, Randolph and Tucker counties, West Virginia, which was established as a wilderness by Public Law 93-622, January 3, 1975.
Cranberry Wilderness Study Area comprises 14,702 ha in the Monongahela National Forest, Pocahontas and Webster Counties, east-central West Virginia. The area is in the Yew Mountains of the Appalachian Plateaus and is at the eastern edge of the central Appalachian coal fields. Cranberry Glades, a peatland of botanical interest lies at the southern end of the study area. All surface rights in the area are held by the U. S. Forest Service; nearly 90 percent of the mineral rights are privately-owned or subordinate to the surface rights.
A mineral resource evaluation of the Rock River Canyon Wilderness Study Area, Alger County, Mich., was completed in 1975 by personnel of the U.S. Geological Survey and the U.S. Bureau of Mines. The area consists of approximately 22 km 2 in the Hiawatha National Forest. Rocks exposed in the area include sandstone, shaly sandstone, dolomitic sandstone, sandy dolomite, and a minor amount of conglomerate; these rocks range in age from possibly Precambrian to early Middle Ordovician. A minor amount of unconsolidated glacier-transported debris was deposited during Pleistocene time. No deposits of either metallic or nonmetallic minerals were found. Although resources of stone, sand, and gravel exist in the study area, they are considered to have small economic potential; similar materials are readily available and easily accessible in the surrounding region.
