The Geologic Map Index of Alaska (Map Index) is an online, interactive web mapping application that provides access to an actively growing geographic index of geology-related maps of Alaska and adjacent areas. This online research tool provides the locations and outlines of most DGGS and U.S. Geological Survey (USGS) geologic and geophysical maps of Alaska in a single, interactive web map. It allows searches of the map database by geographic area of interest, keywords, themes, publishing agency, dates, and other criteria. The search results provide links to DGGS's comprehensive, multi-agency publications database, where users may view and download publications for free. No other geographic index of Alaska geologic...
During 2009, the Alaska Division of Geological & Geophysical Surveys continued a program, begun in 2006, of reconnaissance mapping of surficial geology in the proposed natural-gas pipeline corridor through the upper Tanana River valley. The study area is a 12-mi-wide (19.3-km-wide) area that straddles the Alaska Highway from the western boundaries of the Tanacross B-3 and A-3 quadrangles near Tetlin Junction eastward to the eastern boundaries of the Nabesna D-1 and C-1 quadrangles along the Canada border. Mapping during 2008-2009 in the Tanacross and Nabesna quadrangles linked with the mapping completed in the Tanacross, Big Delta and Mt. Hayes quadrangles in 2006-2008. Surficial geology was initially mapped in...
This geologic map is a product of a cooperative project between the U.S. Geological Survey and the U.S. National Park Service to provide geologic information about this part of Canyonlands National Park, Utah. This digital map database contains bedrock data from previously published data that has been modified by the author. New mapping of the surficial deposits represents the general distribution of surficial deposits of the Druid Arch and The Loop 7.5-minute quadrangles.

The paper geologic map of the east part of the Pullman 1 x 2 -degree quadrangle, Idaho (Rember and Bennett, 1979) was scanned and initially attributed by Optronics Speciality Corp. Inc. (Northride, CA) and remitted to the U.S. Geological Survey for furter attribution and publication of the geospatial digital files. The resulting digital geologic map GIS can be queried in many ways to produce a variety of geological maps.

New 1:24,000-scale geologic mapping in the Storm King Mountain7.5' quadrangle, in support of the USGS Western Colorado I-70Corridor Cooperative Geologic Mapping Project, provides new dataon the structure on the south margin of the White River upliftand the Grand Hogback and on the nature, history, anddistribution of surficial geologic units.Rocks ranging from Holocene to Proterozoic in age are shown onthe map. The Canyon Creek Conglomerate, a unit presently knownto only occur in this quadrangle, is interpreted to have beendeposited in a very steep sided local basin formed bydissolution of Pennsylvanian evaporite late in Tertiary time.At the top of the Late Cretaceous Williams Fork Formation is aunit of sandstone,...

The geologic map described in this study covers the Horse Mesa Dam Quadrangle (1:24,000) (Figure 1) (Sheets I-III). The area encompasses part of the northern Superstition Mountains and southern Mazatzal Mountains. Bedrock in this area consists largely of Proterozoic granitic and metamorphic rocks overlain by a thick sequence of early Miocene volcanic rocks. The study in one of a series of related geologic maps from the Arizona Geological Survey that cover the Superstition volcanic field and adjacent areas (Ferguson and Gilbert, 1997; Ferguson and Skotnicki, 1995; Skotnicki and Ferguson, 1995, 1996; Skotnicki and Leighty, 1997; Spencer and Richard, 1995). The rugged physiography of the area is dominated by drainages...

The Sawtooth Mountains are a small (45 km2 ), low-relief (250 m), yet rugged range composed of essentially flat-lying, Mid-Tertiary volcanic rocks. Along with the West Silver Bell Mountains, which consist mostly of Middle Proterozoic granitic rocks, the ranges form the southwestern boundary ofthe Picacho basin, a major north-trending, approximately 20 km-wide, 3 l<m-deep basin in the Basin and Range structural province of southern Arizona. Access on paved roads is possible from Interstate 10, taking Sunland Gin Road about 20 km south to within few kilometers ofthe Sawtooth Mountains. From this point, four-wheel drive vehicles are required to negotiate the crossings of sandy washes on all roads that lead into the...

The State Geologic Map Compilation (SGMC) geodatabase of the conterminous United States (https://doi.org/10.5066/F7WH2N65) represents a seamless, spatial database of 48 State geologic maps that range from 1:50,000 to 1:1,000,000 scale. A national digital geologic map database is essential in interpreting other datasets that support numerous types of national-scale studies and assessments, such as those that provide geochemistry, remote sensing, or geophysical data. The SGMC is a compilation of the individual U.S. Geological Survey releases of the Preliminary Integrated Geologic Map Databases for the United States. The SGMC geodatabase also contains updated data for seven States and seven entirely new State geologic...
