Raster showing change in water-table altitude between Fall of 2002 and Fall of 2015 in the alluvium in the Lower Arkansas River Valley, Southeast Colorado. Hereafter "fall" is defined as June 1 to November 30. All interpolation and geoprocessing was done using ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011).

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 raster dataset shows the thickness of the alluvium in the Lower Arkansas River Valley, Southeast Colorado. The bottom boundary defined by bedrock (Hurr and Moore, 1972; Nelson and others, 1989a, b, c) and top boundary defined by land surface from U.S. Geological Survey National Elevation Dataset (2016). All interpolation and geoprocessing was completed in ArcGIS Desktop v10 (Environmental Systems Research Institute, 2011).

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...

This digital data release contains geospatial geologic data compiled for the Lamar 250k quadrangle, a region in eastern Colorado and western Kansas, which is predominantly covered by Quaternary deposits that overlay Cretaceous bedrock. Geologic data, compiled from published sources, include the location and characteristics of geologic contacts and faults, mapped geologic polygons, and ammonite fossils. The geologic database includes spatial feature classes that collectively contain the geologic information that are presented in the previously published map plate. The spatial data are accompanied by non-spatial tables that describe the sources of geologic information, a description of geologic map units, a glossary...
