From summary: During 1983 and 1984, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to assess the mineral resource potential and appraise the identified resources of a part of the Far South Egans (NV-040-172) Wilderness Study Area. The area studied encompasses about 63.5 mi2 (square miles) (42,316 acres) in Lincoln and Nye Counties, Nevada, and is in the southern part of the Egan Range of east-central Nevada.

From summary: The USGS (U.S. Geological Survey) and the USBM (U.S. Bureau of Mines) studied the mineral resource potential of 50,499 acres of the 61,137-acre Weepah Spring Wilderness Study Area (NV-040-246), Lincoln and Nye Counties, Nev., at the request of the BLM (U.S. Bureau of Land Management). In this report, the area studied is referred to as the "wilderness study area" or the "study area." Field studies of the area were conducted during summer 1984 by USBM geologists and during spring 1984 and fall 1985 by USGS geologists, geochemists, and geophysicists.

Base from U.S. Geological Survey; Oak Spring, Plutonium Valley, Tippipah Spring, and Yucca Flat 1:24,000, 1960; Jangle Ridge, Mine Mountain, Paiute Ridge, Rainier Mesa, and Yucca Lake 1:24,000, 1961; 20,000 foot grid based on Nevada coordinate system, central zone

From purpose and scope: The purpose of this report is to present all the previously collected hydrogeologic, geophysical, and hydrochemical data on well J-13, and to reanalyze these data, using newly developed methods of analysis.
