Estimated resources of non-leased federal coal, Powder River Basin, Montana and Wyoming

Maps are generated by combining digital ownership data with geologic resource estimates and other spatial coal data in a geographic information system (GIS). For example, we merged the newly compiled Federal coal ownership files with resource calculations from the 1970's for the Powder River Basin (Trent, 1986). For the first time, we are able to visually display the location of Federally owned co

Free-air gravity anomaly map of the Long Island Platform

The U.S. Geological Survey (USGS) has collected marine gravity data along the U.S. Atlantic continental margin during the last decade. This map of the Long Island platform combines the data used to make the preliminary free-air gravity anomaly map of the Atlantic continental margin (Grow and others, 1976) with the new gravity values collected aboard the RV Gilliss in 1979 and the RV Gyre in 1981.

Geochemical map of the Chama River Canyon Wilderness and contiguous roadless area, Rio Arriba County, New Mexico

The Chama River Canyon Wilderness, in Rio Arriba County, north-central New Mexico, covers 50,300 acres (20,364 hectares) within the Coyote and Cuba Ranger Districts of the Santa Fe National Forest and the Canjilon Ranger District of the Carson National Forest. In 1979 the U.S. Forest Service, under the Forest Service Roadless Area Review and Evaluation (RARE II) program, designated three additiona

Geochemical map of the North Fork John Day River Roadless Area, Grant County, Oregon

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. Results must be made available to the public and submitted to the President and the Congress. This report presents the analytical results of a geochemical survey of the Nort
