Structure contour map of the tops of the Kreyenhagen Formation and Cretaceous strata in the Coalinga area, Fresno and Kings counties, California
This structure contour map, originally compiled during a study of the 1983 Coalinga earthquakes, shows the general structural configuration of the upper several kilometers of section in the Coalinga area. It was compiled by using electric well-log data available through April 1982 (Ammann Map Services, 1978; Petroleum Information Corporation, 1982; California Division of Oil and Gas, 1982) and sur
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Cypress Roadless Area, Kern County, California
The Cypress Roadless Area comprises approximately 3 square miles (1,949 acres) of Sequoia National Forest, Kern County, California. The area is at the southern end of the Sierra Nevada, approximately 30 miles east-northeast of Bakersfield, and 2.5 miles and 3.5 miles south-southeast of the communities of Bodfish and Lake Isabella, respectively (index map). Geochemical sampling was conducted during
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, east part of the Raymond Peak Roadless Area, Alpine County, California
The Raymond peak Roadless Area consists of two separate units. The west part (5985), about 12 miles southwest of Markleeville in Stanislaus National Forest, has been studied separately as part of the Mokelumne Wilderness and vicinity (McKee and others, 1982). The east part (4985) is discussed here.
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Pyramid Roadless Area, El Dorado County, California
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 be submitted to the President and the Congress. This report presents the results of a geochemical survey of the Pyramid Road
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Sweetwater Roadless Area, Mono County, California and Lyon and Douglas Counties, Nevada

This roadless area, which lies just east of the Sierra Nevada range, exhibits rugged topography. Elevations range from about 6,160
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrates, Carson-Iceberg and Leavitt Lake Roadless Areas, Alpine, Mono, and Tuolumne counties, California
The Carson-Iceberg and Leavitt Lake Roadless Areas (the study area) lie near the crest of the Sierra Nevada in central California. The study area encompasses approximately 219,630 acres in the Stanislaus and Toiyabe National Forests in Alpine, Mono, and Tuolumne Counties. The area is dominated by rugged topography typical of the high Sierra Nevada. Elevations range from about 4,920 feet at Donn
