High-Resolution Aeromagnetic Survey of the Skykomish Area, Washington High-Resolution Aeromagnetic Survey of the Skykomish Area, Washington
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
Data release for Geologic Map of the Homestake Reservoir 7.5' quadrangle, Lake, Pitkin, and Eagle Counties, Colorado Data release for Geologic Map of the Homestake Reservoir 7.5' quadrangle, Lake, Pitkin, and Eagle Counties, Colorado
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...
High-Resolution Aeromagnetic Survey of the Pasco Area, Washington and Oregon High-Resolution Aeromagnetic Survey of the Pasco Area, Washington and Oregon
This data release provides access to a low-altitude, aeromagnetic survey of a part of south-central Washington and north-central Oregon. The survey extends from the Blue Mountains westward to the Cascade Range and covers the Oregon cities of The Dalles, Hermiston, and Milton Freewater and the Washington cities of Richland, Pasco, Kennewick, and Walla Walla. Data were acquired during the...
Data Release for Geologic Map of Petroglyph National Monument and Vicinity, Bernalillo County, New Mexico Data Release for Geologic Map of Petroglyph National Monument and Vicinity, Bernalillo County, New Mexico
This geologic map depicts and briefly describes geologic units underlying Petroglyph National Monument and immediately adjacent areas in Bernalillo County, New Mexico. The Monument is underlain dominantly by Quaternary basalts of the Albuquerque Volcanoes volcanic field, a series of basin-filling volcanic flows and associated vents from a monogenetic volcanic highland along the eastern...
Water chemistry data for selected hot springs and rivers in Southwest Yellowstone National Park, Wyoming Water chemistry data for selected hot springs and rivers in Southwest Yellowstone National Park, Wyoming
Water analyses are reported for 66 samples collected from numerous thermal and non-thermal (rivers and streams) features in the southwestern areas of Yellowstone National Park (YNP) during 2009, 2017, and 2018. Water samples were collected from sources near Boundary Creek, Bechler River, Falls River, Mountain Ash Creek, Upper Snake River, Spirea Creek, and Lewis Lake. These water samples...
Data release for Middle Pleistocene formation of the Rio Grande Gorge, San Luis Valley, south-central Colorado and north-central New Mexico, USA: Process, timing, and downstream implications Data release for Middle Pleistocene formation of the Rio Grande Gorge, San Luis Valley, south-central Colorado and north-central New Mexico, USA: Process, timing, and downstream implications
This dataset includes tables of 3He-isotopic data used to calculate surface exposure ages for samples of basalt, and U- and Th-isotopic data used to calculate uranium-series age estimates (230Th/U method) and initial 234U/238U activity ratios for samples of pedogenic carbonate formed in soils on alluvial fans in the San Luis Valley, Colorado, USA. These data are included in the...
