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.

Generalized geologic map of the Absaroka-Beartooth study area, south-central Montana
No abstract available.
Generalized surficial geologic map of the Denver 1° x 2° quadrangle, Colorado
Thirty-nine types of surficial geologic deposits and residual materials of Quaternary age are described and mapped in the greater Denver area, in part of the Front Range, and in the piedmont and plains east of Denver, Boulder, and Castle Rock. Descriptions appear in the pamphlet that accompanies the map. Landslide deposits, colluvium, residuum, alluvium, and other deposits or materials are describ
Geologic and structure maps of the Kalispell 1° x 2° quadrangle, Montana, and Alberta and British Columbia
This dataset was digitized by the U.S. Geological Survey EROS Data Center and U.S. Geological Survey Spokane Field Office for input into an Arc/Info geographic information systsem (GIS). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

Geologic map of the Grand Canyon 30' x 60' quadrangle, Coconino and Mohave Counties, northwestern Arizona
This digital map database, compiled from previously published and unpublished data as well as new mapping by the author, represents the general distribution of bedrock and surficial deposits in the map area. Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the Grand Canyon area. The database delineates map units that are identif
Geologic map of the Lone Pine 15' quadrangle, Inyo County, California
Oblique aerial view west across Owens Valley in Lone Pine 15' quadrangle. In distance, Sierra Nevada, capped by Mount Whitney (elev. 14,494 ft; 4,418 m). In middle distance, Alabama Hills, town of Lone Pine, and Owens River. In foreground, Kern Knob, at base of Inyo Mountains. Movement along Owens Valley Fault Zone, at base of Alabama Hills, caused great Lone Pine earthquake of 1872 (estimated Ric
Geologic map of the Palisade quadrangle, Mesa County, Colorado
The Palisade 1:24,000 quadrangle is in Mesa County in western Colorado. Because the map area is dominated by various surficial deposits, the map depicts 22 different Quaternary units. Two prominent river terraces are present in the quadrangle containing gravels deposited by the Colorado River. The map area contains many mass movement deposits. Extensive landslide deposits are present along the eas
Geologic map of the Proterozoic rocks of the central Front Range, Colorado

Geologic map of the Sasquatch Steps area, north flank of Mount St. Helens, Washington
The 1980 eruption of Mount St. Helens resulted in both new volcanic deposits and deeply incised exposures into pre-1980 deposits. These exposures were produced by excavation of the crater by the 1980 landslides and lateral explosion as well as the subsequent erosion of Step and Loowit creeks by northerly stream flow out of the horseshoe-shaped crater. The map covers the area known as the Sasquatch
Geologic map of the Snoqualmie Pass 30 x 60 minute quadrangle, Washington
The Snoqualmie Pass quadrangle lies at the north edge of a Tertiary volcanic and sedimentary cover, where the regional structural uplift to the north elevated the older rocks to erosional levels. Much of the quadrangle is underlain by folded Eocene volcanic rocks and fluvial deposts of an extensional event, and these rocks are overlain by Cascade arc volcanic rocks: mildly deformed Oligocene-Mioce
