Maps

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.

Map showing earthquake intensity zonation and distribution of Quaternary deposits San Mateo, Santa Cruz, and Monterey counties, California

This map is one in a series of six geologic hazards maps being compiled by the U.S. Geological Survey for use by the California Coastal Commission-Central Coast Regional Commission and other planners within the tri-county region. This map is intended for general use in first-step planning and is not a substitute for detailed site investigations.

Map showing faults with Quaternary displacement, northeastern San Francisco Bay region, California

This map shows faults with Quaternary displacement in the northeast San Francisco Bay region of California. Faults that have been historically active or that show evidence of movement during approximately the last 2 million years (the Quaternary Period) are delineated and are classified according to the age of their last surface displacement.The map is designed to provide a synopsis of Quaternary

Map showing free-air gravity anomalies in the southern Beaufort Sea

Free-air gravity anomaly data used in this compilation were obtained from the U.S. Geological Survey; the University of Connecticut Institute of Marine Sciences; and the Earth Physics Branch, Department of Energy, Mines, and Resources, Canada.Bathymetric contours are based primarily upon water-depth data (uncorrected) collected together with the gravity data. Water depths were reported every half

Map showing general availability of ground water in the Kaiparowits coal-basin area, Utah

This is one of a series of maps that describe the geology and related natural resources in the Kaiparowits coal-basin area. This map is based partly on records of water wells, springs, and coal and petroleum exploration holes, partly on unpublished reports of field evaluations of prospective stock-water well sites by personnel of the U.S. Geological Survey, and partly on a 6-day field reconnaissan

Map showing general chemical quality of ground water in the Kaiparowits coal-basin area, Utah

This is one of a series of maps that describe the geology and related natural resources in the Kaiparowits coal-basin area. Chemical analyses of water from about 40 widely scattered springs, 20 coal-exploration holes in the Kaiparowits Plateau, and 7 water wells in the vicinity of the communities of Escalante and Glen Canyon were used to compile this map. All the water samples were from depths of
