Fundamental Science Practices
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Geochemical map showing anomalous concentrations of selected elements in stream sediments from the Golden Trout Wilderness, California
The Golden Trout Wilderness occupies 457 square miles in the southern Sierra Nevada range of California, south of Sequoia National Park. The study area includes at least a part of the Kern Peak, Olancha, Mineral King, Hockett Peak, Camp Nelson, and Manache Mountain 15-minute quadrangle maps. It is contained totally within lands belonging to the Inyo and Sequoia National Forests.
Geochemical map showing anomalous concentrations of selected elements in the nonmagnetic heavy-mineral concentrates from the Golden Trout Wilderness, California
The Golden Trout Wilderness occupies 457 square miles in the southern Sierra Nevada range of California, wouth of Sequoia National Park. The study area includes at least a part of Kern Peak, Olancha, Mineral King, Hockett Peak, Camp Nelson, and Monache Mountain 15 minute quadrangle maps. It is contained totally within lands belonging to the Inyo and Sequoia National Forests.
Geochemical maps of Bunk Robinson Peak and Whitmire Canyon Roadless Areas, Hidalgo County, New Mexico, and Cochise County, Arizona
Geochemical sampling of the Bunk Robinson Peak and Whitmire Canyon Roadless Areas was completed in the spring of 1980. The purpose of the geochemical sampling was to determine if certain metals, and "pathfinder" elements in heavy-mineral concentrates and stream sediments are enriched beyond normal black-ground amounts. The enrighment of elemental contents above background amounts in these samples

Geochemical maps of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana
The Selway-Bitterroot Wilderness covers almost 2,000 mi2 in east-central Idaho and western Montana (fig. 1). The wilderness lies across the Bitterroot Range, which forms the boundary between Idaho and Montana, and includes large portions of the drainages of the Selway, Lochsa, and Bitterroot Rivers. Elevations range from 1,800 ft on the Selway River near the wilderness boundary to 10,157 ft at Tra
Geologic and aeromagnetic maps and mineral resource potential survey of the Blackjack Springs Wilderness, Vilas County, Wisconsin
The mineral resource potential of the Blackjack Springs Wilderness in the Nicolet National Forest, Vilas County, Wisc., was evaluated in 1982. No bedrock exposures are known in or near the wilderness. Geophysical data and regional geologic relations suggest that the area consists mostly of recrystallized and deformed mafic volcanic rocks and associated mafic intrusives of Early Proterozoic age.

Geologic and mineral resource potential map of the Chambers Ferry Roadless Area, Sabine National Forest, Sabine County, Texas
Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe" when the act was passed were incorporated into the National W
