Efforts by the USGS to characterize regional geology of the southeastern Mojave Desert near Mountain Pass, California, include 1,061 rock samples collected along the southern California/Nevada border. Rock property measurements include density, magnetic susceptibility, and radiometric concentrations to understand structural and geophysical relationships associated with rare earth element mineral d

This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington centered approximately 22 km west-southwest of Ellensburg. The survey includes the cities of Ellensburg, Cle Elum, and Yakima and is referred to as the Cle Elum aeromagnetic survey. The Cle Elum aeromagnetic survey extends from the Columbia Plateau westward to the eastern Cascade Range and illu

This data release provides access to a low-altitude, aeromagnetic survey over parts of Missouri, Arkansas, and Tennessee, an area centered about 100 km north of Memphis, Tennessee. The survey covers parts of the southern arm of the New Madrid seismic zone, the northwestern margin of the Reelfoot rift, the Blytheville arch, and the Commerce geophysical lineament (reference: Langenheim, V.E., and Hi

This data release provides access to a low-altitude, aeromagnetic survey over a part of northeastern Oregon, an area centered approximately over the city of La Grande. The survey is underlain by pre-Tertiary intrusive and metamorphic rocks exposed in the Wallowa Mountains and southern Blue Mountains, and basalts of the Miocene Columbia River Basalt Group exposed or shallowly buried elsewhere. The

A high-resolution airborne magnetic and radiometric survey of the southeast Mojave Desert, parts of California and Nevada was flown by EDCON-PRJ, Inc. from December 13, 2019 to March 21, 2020. The high-resolution fixed-wing survey was flown at a flightline spacing of 200 m, an azimuth of 70 degrees, a nominal elevation above ground of 100 m, and consists of about 17,277 line-kilometers.

This data release provides access to a low-altitude, aeromagnetic survey of a part of eastern Washington and northwestern Idaho centered approximately at Spokane, Washington, and referred to as the Spokane aeromagnetic survey. The survey includes the cities of Spokane and Cheney, numerous smaller communities, and Fairchild Air Force Base. Magnetic anomalies reflect Miocene rocks of the Columbia Ri

This data release provides access to a low-altitude, aeromagnetic survey of a part of central Washington, an area that includes the city of Wenatchee and the towns of Entiat, Chelan, and Leavenworth. The Wenatchee aeromagnetic survey extends westward from the Columbia Plateau to the Cascade Range, and covers a part of the Columbia River and Lake Chelan. The survey was conducted between October 17

This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington centered approximately 30 km east of Yakima and referred to as the Hanford aeromagnetic survey. The survey includes the city of Richland, numerous smaller communities, and the Hanford Site (https://www.hanford.gov). The Hanford aeromagnetic survey extends from the Columbia Plateau westwar

This dataset consists of 14 magnetotelluric (MT) stations collected in 2015 near San Pablo Bay, California along a east-northeast profile. The U.S. Geological Survey acquired these data to understand the fault geometry of the Hayward Fault and the Rodgers Creek Fault.

The data in this release originate from a low-altitude, aeromagnetic survey of the Centralia and Chehalis area of southwestern Washington. The survey was conducted between September 22 and October 22, 2015, by Eon Geosciences, Inc, working under contract to the U.S. Geological Survey. The covered region extends from the Cascade Range in the east to Willapa Bay in the west, and includes the cities

This data release provides access to a low-altitude, aeromagnetic survey of a part of north-central Washington. The survey is centered approximately 120 km northwest of Yakima and includes the small town of Skykomish. The Skykomish aeromagnetic survey covers a part of the central Cascade Range of Washington, the western portion of the Jurassic ophiolitic Ingalls tectonic complex, and the Cretaceou

This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington and north-central Oregon.
