Wildland-urban interface maps for the conterminous U.S. based on 125 million building locations
The wildland-urban interface (WUI) is the area where urban development occurs in close proximity to wildland vegetation. WUI maps for the conterminous U.S. were generated using building point locations, offering higher spatial resolution compared to previously developed WUI maps based on U.S. Census Bureau housing density data (Radeloff et al., 2017). Building point locations were obtained from a
Literature compilation of paleocurrent data from the Late Paleozoic Ouachita orogen, Oklahoma-Arkansas, U.S.A.
This digital geospatial compilation gathered paleoflow indicators from current-formed sedimentary structures throughout the Paleozoic Ozark uplift, Arkoma foreland basin, and Ouachita fold-thrust-belt of eastern Oklahoma and western Arkansas from existing publications. This dataset consists of unidirectional and bidirectional paleocurrents observed from a variety of bedform types represented by ap
Data Release - Digital subsurface data from previously published contoured maps of the tops of the Mowry Shale, Morrison Formation, and Minnelusa Formation, Powder River basin, Wyoming and Montana
This digital data release contains previously published contours on the tops of the Mowry Shale, Morrison Formation, and Minnelusa Formation. The maps are from a series of U.S. Geological Survey Miscellaneous Field Studies (MF) showing computer-generated structure contours, isopachs, and cross sections of selected formations in the Powder River basin, Wyoming and Montana (Crysdale 1990, 1991a, 199
Data Release for Luminescence: Paleoseismic liquefaction associated with Holocene earthquakes on the Wallula Fault zone, Southeast Washington, USA
Observations of widespread liquefaction and stratigraphic and structural relationships in a trench across an ambiguous scarp are used to constrain the timing of Holocene earthquakes on the northwest-striking Wallula fault zone in southeast Washington and Oregon. Additional observations and age constraints from OSL analysis of samples collected from large-scale liquefaction features that crosscut t
Data Release for Luminescence: Late Holocene rupture history of the Ash Hill Fault, Eastern California Shear Zone, and the potential for seismogenic strain transfer between nearby faults
The following report summarizes the dating results from sedimentary deposits exposed by soil pits in Panamint Valley, CA. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and dating-related calculations.
Digital subsurface data from previously published maps of the base and thickness of post-Eocene continental deposits in the Sacramento Valley, California
Post-Eocene (predominantly Pliocene) continental sedimentary rocks of the Sacramento Valley, CA are up to 1,200 m thick beneath the valley. These rocks contain most of the fresh ground water in the valley, forming a key component of the total water budget for the valley. A 1974 study by the U.S. Geological Survey was an early attempt to develop detailed knowledge of the subsurface geology of the S
A geodatabase of Surficial Geology of the Allentown 30x60-Minute Quadrangle in Pennsylvania digitized from the original map of Braun, 1996
This Scientific Data Release is a spatial geodatabase representation of Braun, D. D., 1996, Surficial geology of the Allentown 30x60-minute quadrangle: Pennsylvania Geological Survey, 4th ser., Open-File Report 96-48, 17 p., 1 map, scale 1:100,000. These geospatial data depict surficial geologic materials in the Pennsylvania portion of the Allentown 30 x 60-minute quadrangle in eastern Pennsylvani
Digital subsurface data from previously published contour map of the top of the Wilcox Group, northern Gulf of Mexico coastal region
The lower Paleogene Wilcox Group crops out around the northern edge of the Gulf of Mexico Basin and is a major coal-bearing unit and a primary oil and gas producer in the lower Paleogene section of the Gulf Coast region. The outcrop distribution of the Wilcox Group and other coal-bearing strata of the Gulf Coast region was compiled as part of a U.S. Geological Survey National Coal Assessment (Warw
Fault data collected between 1996 and 2019 from the Buffalo River watershed area, northern Arkansas
Information on the locations and characteristics of faults were collected while conducting fieldwork between 1996 and 2019 in support of geologic mapping in the Buffalo River watershed area of northern Arkansas. A total of 1274 entries on faults were recorded at 452 sites. The observations associated with faults include seven categories of increasing completeness of information.
Database for the geologic map of the upper Santa Cruz River basin, southern Arizona
This digital publication contains the database, base maps, and style files used to build the geologic map of the upper Santa Cruz River basin in southern Arizona published in U.S. Geological Survey Scientific Investigations Map 3490 (Page and others, 2023). Shapefiles are also included for the user’s convenience. In the database, there are polygon features outlining the map units and data sources;
Digital subsurface data from previously published contoured maps of the top of the Dakota Sandstone, Uinta and Piceance basins, Utah and Colorado
The top of the Upper Cretaceous Dakota Sandstone is present in the subsurface throughout the Uinta and Piceance basins of UT and CO and is easily recognized in the subsurface from geophysical well logs. This digital data release captures in digital form the results of two previously published contoured subsurface maps that were constructed on the top of Dakota Sandstone datum; one of the studies a
Data release for cosmogenic beryllium-10 exposure ages of moraine boulders in the Stura Valley, Maritime Alps, northwestern Italy
This report summarizes the cosmogenic beryllium-10 (10Be) geochronologic results from boulders deposited on moraines in the Stura Valley of the Maritime Alps, the southwestern most extent of the European Alpine mountain chain, northwestern Italy.
