Data

Airborne electromagnetic (AEM) and magnetic survey data were collected from December 2022 through March 2023 over a distance of 11,079 line kilometers in western Nevada and eastern California; central Nevada; and northern Nevada and southeastern Oregon. These data were collected in support of the U.S. Geological Survey (USGS) Earth Mapping Resources Initiative (Earth MRI), which aims to...

This U.S. Geological Survey (USGS) data release contains data from stream water, groundwater, and stream sediment samples collected in August 2023 in the East Mancos River watershed in southwestern Colorado. Data were collected as part of a study aimed at identifying sources of elevated metal concentrations in the stream. Eighteen streambank wells were installed in pairs at nine...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over the Sierra Madre-Elkhead Mountains-Medicine Bow Mountains region of southern Wyoming and northern Colorado. The airborne survey was funded by the Earth Mapping Resources Initiative. The survey was designed to meet complementary needs related to geologic mapping and

This data release contains digital radiometric flight line data for a high-resolution airborne magnetic and radiometric survey over southeastern Illinois, western Kentucky, and southern Indiana, 2019 (version 2.0, August 2025). Data and documentation for the original version, including associated airborne magnetic data, can be found at https://doi.org/10.5066/P9R05B0M. The airborne...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the reconnaissance geologic map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana (Toth, 1983). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic...

This data set includes the magnetotelluric (MT) sounding data collected from 1997 to 2004 in and near the Rio Grande rift, New Mexico. The U.S. Geological Survey conducted a series of multidisciplinary studies, including audiomagnetotelluric (AMT) surveys, in the Rio Grande rift to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the Hailey 1 x 2 degree quadrangle, Idaho (Worl and others, 1991). Attribute tables and geospatial features (lines and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in Idaho Geological Survey Geologic Map 10 (Worl and...

This data release provides Geologic Map Schema (GeMS)-compliant GIS data for new geologic mapping of the Bison Range and surrounding area on the Flathead Reservation, northwestern Montana. The database represents the geology for the 150 square kilometer, geologically complex map area, at a publication scale of 1:24,000. The map covers parts of Sanders and Lake Counties, Montana. All...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was funded by the Earth Mapping Resources Initiative and was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 45...

This data release is a collection of quantitative and qualitative data for fluid inclusions in samples from the Bear Lodge alkaline complex, Wyoming. The dataset includes:microthermometry, Raman spectroscopy, noble gas spectroscopy, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and energy dispersive X-ray analyses of fluid inclusions. For spatial context and...

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the central part of the Northern Park Range, Jackson and Routt Counties, Colorado (Snyder, 1980). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (USGS NCGMP, 2020) and represent the geologic map as published in USGS...
