Fundamental Science Practices

USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.

Learn More

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.

Median-porosity contour maps of the J Sandstone, Dakota Group, in the Denver Basin, Colorado, Nebraska, and Wyoming

The Lower Cretaceous J sandstone of the Dakota Group is present in the Denver basin in eastern Colorado, southeastern Wyoming, and southwestern Nebraska. Deposited during a regression of the Cretaceous epicontinental sea, this informally named unit is composed primarily of sandstone and shale of deltaic and near shore-marine origin. The J sandstone can be divided into an upper transgressive sand,

Mineral resource potential map of the South Sierra Wilderness and the South Sierra Roadless Area, Inyo and Tulare Counties, California

There are five areas with mineral resource potential and one area with geothermal energy potential in the South Sierra Wilderness and the South Sierra Roadless Area. The area south of Summit Meadows and the area south of Hogback Creek have moderate resource potential for tungsten and molybdenum in small skarn deposits. The area between Summit meadow and Hogback Creek and the area from south of Jac

Mines, prospects, and occurrences of metallic minerals and barite, Springfield 1° by 2° Quadrangle, Missouri

This map is part of a folio of maps of the Springfield 1° x 2° quadrangle, Missouri, prepared under the Conterminous United States Mineral Assessment Program.  Other publications in this folio to data include U.S. Geological Survey Miscellaneous Field Studies Maps MF-1830-A and B and Missouri Geological Survey Open-file Report OFR-85-42-MR.  Additional maps showing various geologic aspects of the

Oblique map of the northern Sierra Nevada, California, showing location of gold-bearing areas

More than a third of the gold produced by the United States was mined in California. The bulk of this gold was recovered from the western slope of the northern half of the Sierra Nevada between the Merced River in the south and the Feather River to the north, a distance of about 170 mi. Gold was first discovered, in this region, on the American River at Coloma in 1848, triggering the famed Califor

Oblique map showing maximum extent of 20,000-year-old (Tioga) glaciers, Yosemite National Park, central Sierra Nevada, California

This map shows the alpine ice field and associated valley glaciers at their maximum extent during the Tioga glaciation. The Tioga glaciation, which peaked about 15,000-20,OOO years ago, was the last major glaciation in the Sierra Nevada. The Tuolumne ice field fed not only the trunk glacier that moved down the Tuolumne River canyon through the present-day Hetch Hetchy Reservoir, but it also overfl
