These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The U.S. Geological Survey developed this dataset as part of the Colorado Front Range Infrastructure Resources Project (FRIRP). One goal of the FRIRP was to provide information on the availability of those hydrogeologic resources that are either critical to maintaining infrastructure along the northern Front Range or that may become less available because of urban expansion in the northern Front Range. This dataset extends from the...

This data release provides a generalized lithology look-up table for the lithogeochemical classification of Vermont's bedrock geologic map units. The table is defined from the mapped bedrock geologic units published by Ratcliffe and others (2011) and the generalized lithology of rock group A and rock group B for lithogeochemical classification as defined by Robinson and Kapo (2003). The 2003 classification was created for all six New England states and Vermont's geologic units were based on an older, less detailed, bedrock map of Vermont by Doll and others (1961). The new data table in this data release is designed to be joined with the published attribute table from the 2011 map database, as part of the bedrock...

This data release contains 3-meter gridded rasters of depth to bedrock below bathymetric surface, the thickness of unconsolidated sediment, and the volume of unconsolidated sediment within a 2.6-km reach of the Similkameen River, Okanogan County, Washington, impounded by Enloe Dam. These rasters were calculated from continuous resistivity profiles (CRP) surveyed using a SuperSting R8 8-channel resistivity meter with a CRP streamer containing a 100-m long array of 11 electrodes was towed behind a boat spaced at 10 m. After collection, the raw CRP files were georeferenced to coordinates concurrently by a global positioning system. Output files were merged and linearized. This was converted to a data file compatible...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This geographic information system (GIS) data layer shows the generalized lithologic and geochemical, termed lithogeochemical, character of near-surface bedrock in the New England Coastal Basins (NECB) study area of the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program. The area encompasses 23,000 square miles in western and central Maine, eastern Massachusetts, most of Rhode Island, eastern New Hampshire...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This geospatial data set describes bedrock geology of the Turkey Creek drainage basin in Jefferson County, Colorado. It was digitized from maps of fault locations and geologic map units based on age and lithology. Created for use in the Jefferson County Mountain Ground-Water Resources Study, it is to be used at a scale no more detailed than 1:50,000.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The hydrogeologic framework for the Lake Michigan Basin model was developed by grouping the bedrock geology of the study area into hydrogeologic units on the basis of the functioning of each unit as an aquifer or confining layer within the basin. Available data were evaluated based on the areal extent of coverage within the study area, and procedures were established to characterize areas with sparse data coverage. Top and bottom...

This data release contains two child item datasets including a compilation of available chloride concentration data in groundwater and related isochlors as well as geospatial data defining the hydrogeologic framework for Kings, Queens, and Nassau Counties in Long Island, New York. These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/lisustainabilityphase1viewer/
The Arizona Geological Survey (AZGS) is committed to making its geologic products freely available online to a variety of consumers of geologic information and data. To this end, AZGS proposed two projects under the 2021-2022 National Geological and Geophysical Data Preservation Program (NGGDPP) to increase the availability of its data. First, AZGS converted 32 of its older geologic maps that existed only as PDF scans into modern digital geodatabases. Each of these preserved maps was then archived and re-published at the National Digital Catalog, University of Arizona Campus Repository, Arizona Geological Survey Repository, and National Geologic Map Database. Second, AZGS participated in the annual Earth MRI workshop,...
This child item dataset contains 22,871 records of chloride concentration in groundwater across Kings, Queens, and Nassau Counties in Long Island, New York. Compiled records span the period from 1889 to 2022. Records are provided in a shapefile of point data compiled from several sources detailed in the metadata. Chloride isolines (isochlors) are also included as a shapefile of interpolated point data representing average conditions over 11 twenty-year time periods in the two main Long Island aquifer complexes (Upper glacial-Jameco-Magothy and North Shore-Lloyd). Interpolation methods are discussed in Stumm and others (2024). These data are accessible as an online webmap: https://ny.water.usgs.gov/maps/lisustainabilityphase1viewer/

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This data layer shows the generalized lithologic and geochemical (lithogeochemical) character of near-surface bedrock in the Connecticut, Housatonic, and Thames River Basins and several other small basins that drain into Long Island Sound from Connecticut. The area includes most of Connecticut, western Massachusetts, eastern Vermont, western New Hampshire, and small parts of Rhode Island, New York, and Quebec, Canada. Bedrock geologic...
Raster grids depicting the current knowledge for elevation for the bedrock surface, pre-Mesozoic surface, the Precambrian surface and the basement surface based on the addition of new data from completed mapping. Basement is the top of structurally complex Precambrian rocks where the Phanerozoic and Proterozoic basins are removed based on geophysical modeling and drill hole interpretation. Statewide elevation datasets are stored as contoured line files and attributed with publication source, contour elevation and date and time of last edit. New raster grids are generated with the 'Topo to Raster' tool in ESRI ArcMap 10.7. 6/2023 Update: The 2023 version of rasters are currently not available online to download but...
