This release includes aeromagnetic data collected via low-altitude helicopter flown over northeastern Washington State, centered over the town of Republic, Washington. The data were acquired between September 26, 2022 and August 21, 2023 by Precision Geosurveys, Inc. of Langley, British Columbia and processed by EDCON-PRJ, Inc. of Lakewood, Colorado, contracted by the U.S. Geological Survey and funded through the Earth Mapping Resources Initiative (EarthMRI). The survey includes gridded data from target altitude of 80-100 meters above ground level, subject to aircraft climb and descent limitations. Primary transverse flight lines were flown in the east-west direction and spaced 200 meters apart. Tie lines were flown...

The Homestake Reservoir 7.5' quadrangle lies at the northwestern end of the Upper Arkansas Valley, and headwaters of the Arkansas River, and the Roaring Fork, Fryingpan, and Eagle Rivers of the Colorado River system. The quadrangle lies within tectonic provinces of the 1.4 Ga Picuris Orogeny, the late Paleozoic Ancestral Rockies, Late Cretaceous-Paleocene Laramide orogeny, Oligocene to Miocene, and Pliocene?, volcanism, and Miocene to the present Rio Grande rift extensional tectonics. In the eastern half of the quadrangle, high-angle, east-dipping, Neogene normal faults displace Proterozoic rocks, and locally Mio-Pliocene? volcanic rocks. Many quartz veins and hydrothermally altered zones are exposed along the eastern...

The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980-1986 and 2004-2008. During 2017, U.S. Forest Service contracted the acquisitions of airborne lidar surveys of Mount St. Helens and upper North Fork Toutle River basin, part of a larger 2017-2018 survey of the Gifford Pinchot National Forest. The U.S. Geological Survey combined and reprojected 81 raster datasets, provided by the U.S. Forest Service in October 2018, into a single digital elevation model (DEM) of the ground surface, including beneath forest cover (that is, 'bare earth')....

Airborne magnetic gradiometry data are provided here as part of the data release, "Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020." This website includes the processed aeromagnetic data provided in an ascii .csv file and a geoTIFF image showing the magnetic field intensity. The contractor report is available on the parent page. These data were collected as part of a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina and the surrounding region immediately northwest of an airborne magnetic and radiometric survey collected near Charleston, South Carolina in 2019 (Shah, 2020). Goals included imaging heavy mineral sands containing titanium,...

This data release provides digital flight line data for a high-resolution radiometric survey over the South Pass-Granite Mountains region in central Wyoming. The airborne survey was funded by the state of Wyoming, designed by the Wyoming State Geological Survey (WSGS), and contracted by the USGS. The survey is aligned with 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 47,973.8 line km of radiometric data were acquired over an area of 8639 km2. Data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along N-S flight lines spaced at 200...

This data release provides digital flight line data for a high-resolution airborne magnetic survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and Kennecott Exploration Company. The survey was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 34,041-line km of magnetic and radiometric data were acquired over an irregular-shaped area of 6178 km2. Data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along E-W flight lines spaced at 200 m intervals. Tie lines were flown in an N-S direction...

Magnetic data collected as part of a high-resolution airborne magnetic and radiometric survey over the region surrounding the Wet Mountains of southern Colorado, including parts of Custer and Fremont Counties, are provided as digital flight-line and grid files. Magnetic surveys measure subtle variations in the Earth’s magnetic field and are sensitive to differences in the magnetic properties of rocks from ground level to many kilometers below. Data for this survey were collected by Sander Geophysics Limited International (SGL) under contract with the USGS. The survey was flown in June and July of 2021 using a helicopter equipped with a magnetometer mounted in a stinger extending from the nose of the aircraft. The...

Radiometric data collected as part of a high-resolution airborne magnetic and radiometric survey over the region surrounding the Wet Mountains of southern Colorado, including parts of Custer and Fremont Counties, are provided as digital flight-line and grid files. Radiometric (or gamma-ray) surveys measure naturally occurring low-level radiation and are sensitive to the presence of rocks near the surface that are enriched in uranium, thorium, or potassium. Data for this survey were collected by Sander Geophysics Limited International (SGL) under contract with the USGS. The survey was flown in June and July of 2021 using a helicopter equipped with a gamma-ray spectrometer stowed onboard. The helicopter pilots followed...

The Ozark Plateau aquifer system stretches across approximately 70,000 square miles (mi2) of Arkansas, Missouri, Kansas and Oklahoma, and is composed of many hydrogeologic units, such as the Boone aquifer and the Roubidoux aquifer. However, this data release is focused on only 11,000 mi2 in northern Arkansas, southeastern Kansas, southwestern Missouri, and northeastern Oklahoma. The Boone aquifer covers approximately 10,700 mi2 of this area, and the Roubidoux aquifer covers the 11,000 mi2 area entirely. These aquifers are mostly made of Mississippian-aged and Ordovician-aged carbonate rock, and serve as the main sources of fresh groundwater in northeastern Oklahoma (Imes and Emmett, 1994). In 2017, the U.S. Geological...
