Raster dataset showing saturated thickness (in feet) of the alluvium in the Lower Arkansas River Valley, Southeast Colorado, June 1 - November 30, 2008 (hereafter defined as "fall"). Saturated thickness values based on water levels measured in the study area and median lake level at John Martin Reservoir during this time period. Surface interpolations for water-table altitude were done using Inverse Distance Weighting using coordinate and altitude data from "Wells and water-level altitude in the alluvium in the Lower Arkansas River Valley, Southeast Colorado, Spring and Fall 2002, 2008, and 2015" (see cross reference section in metadata), and surface interpolation of bedrock was done using Topo to Raster using elevation...

This data release includes PHREEQC files used for geochemical models in the Ohio River alluvial aquifer of West Virginia. The associated publication by McAdoo and Connock (2024) should be consulted to understand the purpose and limitations of these simulations and data. The wateq4f database (Ball and Nordstrom, 1991) was used for the PHREEQC simulation. A report by Parkhurst and Appelo (2013) serves as the formal documentation for PHREEQC, and the software is a publicly available from the U.S. Geological Survey at https://www.usgs.gov/software/phreeqc-version-3. Files in this data release include: -OhioRiverAlluviumInput.pqi: Input file used to run the simulations documented in this data release. -OhioRiverAlluviumInput.txt:...

This data release is a geochemical data set from the reanalysis of 23 rock and 85 sediment samples collected between 1966 and 1970 by the U.S. Geological Survey (USGS) for a series of studies investigating the mineral resources of the Idaho Primitive Area (Cater et al., 1973). The samples are from the upper Middle Fork Salmon River and the South Fork Salmon River, including the tributaries of East Fork of the South Fork and Porphyry Creek. The overall objective of this study is to characterize the regional impact of legacy mining for the Frank Church - River of No Return Wilderness Area. In 1980 the U. S. Congress passed the Central Idaho Wilderness Act which combined the Idaho Primitive Area, the Salmon Rivers...

Boundary of the alluvium in the Lower Arkansas River Valley, Southeast Colorado. Boundary defined by extent of available bedrock information and geologic maps. Also includes approximate shoreline of John Martin Reservoir in Bent County, Colorado. Scale of maps used for digitization was 1:62,500. All digitization and geoprocessing was done using ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011)
A previously completed mineral resources assessment of the Texas Coastal Plain indicated the potential for future discovery of uranium resources. Composite hydrogeologic frameworks can be used in geoenvironmental assessments as a tool to understand potential effects of mining operations. Data for a composite hydrogeologic framework are documented in this data release. The hydrogeologic framework focused on the composite hydrogeologic unit consisting of the upper part of the Miocene-age Fleming Formation/Lagarto Clay, Pliocene-age Goliad and Pleistocene-age Willis Sands, Pleistocene-age Lissie and Beaumont Formations, and Holocene-age alluvial sediments (fluvial alluvium and eolian sand deposits). This composite...

This data release presents geologic map data for the surficial geology of the Aztec 1-degree by 2-degree quadrangle. The map area lies within two physiographic provinces of Fenneman (1928): the Southern Rocky Mountains province, and the Colorado Plateau province, Navajo section. Geologic mapping is mostly compiled from published geologic map data sources ranging from 1:24,000 to 1:250,000 scale, with limited new interpretive contributions. Gaps in map compilation are related to a lack of published geologic mapping at the time of compilation, and not necessarily a lack of surficial deposits. Much of the geology incorporated from published geologic maps is adjusted based on digital elevation model and natural-color...

Points representing locations of wells in which water levels were measured, and values of water-level altitudes above the National Geodetic Vertical Datum of 1929 for June 1 to November 30 (hereafter defined as "fall") and December 1 to May 31 (hereafter defined as "spring"), 2002, 2008, and 2015 in the Lower Arkansas River Valley, Southeastern Colorado. Water-level values, John Martin Reservoir lake levels, and land surface altitudes at monitoring wells were gathered from the U.S. Geological Survey National Water Information System (NWIS) and the U.S. Army Corps of Engineers. All geoprocessing was done using ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011).

This 1:50,000-scale geologic map represents a compilation of the most recent geologic studies of the upper Arkansas River valley, between Leadville and Salida, Colorado. The valley is structurally controlled by an extensional fault system that forms part of the prominent northern Rio Grande rift, an intra-continental region of crustal extension. This work also incorporates new detailed geologic mapping of poorly understood areas within the map area and reinterprets previously studied areas, aided by lidar data that covers 59 percent of the map area. The mapped region extends into the Proterozoic metamorphic and intrusive rocks in the Sawatch Range west of the valley and the Mosquito Range to the east. Paleozoic...
