Geologic map of the Cerro Gordo Peak 7.5' Quadrangle, Inyo County, California Geologic map of the Cerro Gordo Peak 7.5' Quadrangle, Inyo County, California
This digital map database, compiled from new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following...
Map showing coastal cliff retreat rates along the Big Sur coast, Monterey and San Luis Obispo Counties, California Map showing coastal cliff retreat rates along the Big Sur coast, Monterey and San Luis Obispo Counties, California
The average coastal cliff retreat rate along the Big Sur coast is 18 ? 6 cm/yr as measured over a 52-year time period. The erosion reference features measured as the cliff edge include the well-defined cliff edges common to marine terraces, slight breaks in the slope defining the upper edge of the active lower slope, and the road grade. Cliff erosion and retreat are focused in isolated...
Maps showing estimated sediment yield from coastal landslides and active slope distribution along the Big Sur coast, Monterey and San Luis Obispo Counties, California Maps showing estimated sediment yield from coastal landslides and active slope distribution along the Big Sur coast, Monterey and San Luis Obispo Counties, California
The 1982-83 and 1997-98 El Ni?os brought very high precipitation to California?s central coast; this precipitation resulted in raised groundwater levels, coastal flooding, and destabilized slopes throughout the region. Large landslides in the coastal mountains of Big Sur in Monterey and San Luis Obispo Counties blocked sections of California State Route 1, closing the road for months at...
Surficial Geologic Map of the Tanacross B-6 Quadrangle, East-Central Alaska Surficial Geologic Map of the Tanacross B-6 Quadrangle, East-Central Alaska
The Tanacross B-6 1:63,360-scale quadrangle, through which the Alaska Highway runs, is in east-central Alaska about 190 km west of the Yukon border. The surficial geologic mapping in the quadrangle is in support of the 'Geologic Mapping in support of land, resources and hazards issues in Alaska' Project of the USGS National Cooperative Geologic Mapping Program. The Tanacross B-6...

Geologic map of the Bend 30- x 60-minute quadrangle, central Oregon Geologic map of the Bend 30- x 60-minute quadrangle, central Oregon
This map presents the stratigraphic and structural setting of volcanic and sedimentary strata deposited during the past 35 million years across 4,430 km2 in central Oregon. Snowfall in the Cascade Range (west part of map area) recharges important aquifers in the Deschutes basin (central part of map). The area includes the majestic peaks of the Three Sisters volcanoes, where continued...
Geologic map of the Hasty Quadrangle, Boone and Newton Counties, Arkansas Geologic map of the Hasty Quadrangle, Boone and Newton Counties, Arkansas
This digital geologic map compilation presents new polygon (for example, geologic map unit contacts), line (for example, fault, fold axis, and structure contour), and point (for example, structural attitude, contact elevations) vector data for the Hasty 7.5-minute quadrangle in northern Arkansas. The map database, which is at 1:24,000-scale resolution, provides geologic coverage of an...
World heritage site - Bien du Patrimoine Mondial - Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek World heritage site - Bien du Patrimoine Mondial - Kluane/Wrangell-St. Elias/Glacier Bay/Tatshenshini-Alsek
The four parks depicted on this map make up a single World Heritage Site that covers 24.3 million acres. Together, they comprise the largest internationally protected land-based ecosystem on the planet. The United Nations Educational, Scientific and Cultural Organization (UNESCO) established the World Heritage Program in 1972 for the identification and protection of the world?s...
Geologic map of the Kanab 30' x 60' quadrangle, Utah and Arizona Geologic map of the Kanab 30' x 60' quadrangle, Utah and Arizona
The 1:100,000-scale geologic map of the sparsely populated Kanab 30' x 60' quadrangle in southernmost Utah and a narrow strip in northernmost Arizona delineates 17 formations and numerous subdivisions of sedimentary rock units of Permian, Triassic, Jurassic, Cretaceous, and Tertiary ages; 12 Quaternary alluvial, eolian, and mass-wasting units; and Quaternary basaltic igneous rocks and...
