This data set consists of a polygon representing the study area for middle Humboldt River basin, north-central Nevada as published in the U.S. Geological Survey Water-Resources Investigations Report 98-4209 titled "Hydrogeologic framework and ground-water levels, 1982 and 1996, middle Humboldt River basin, north-central Nevada," 1999.

This dataset, created in support of USGS Scientific Investigations Report 2020-5075, Estimates of Groundwater Discharge by Evapotranspiration, Stump Spring and Hiko Springs, Clark County, Nevada, 2016-18, represents the groundwater discharge area (GDA) for the Hiko Springs area. Vegetated areas within the GDA are composed of phreatophytic shrubs interspersed with xeric vegetation and bare soil. The GDA was delineated by visual interpretation of 1-meter National Agriculture Imagery Program (NAIP) aerial imagery acquired in May of 2015. Areas of channel scour within the GDA resulting from a flood event in September 2015 were delineated from a 1.84 meter resolution 2016 Worldview 2 image.

This dataset is a polygon coverage of counties limited to the extent of the Upper Freeport coal bed resource areas and attributed with statistics on the thickness of the Upper Freeport coal bed, its elevation, and overburden thickness, in feet. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C.

This dataset is a polygon coverage of counties limited to the extent of the Pittsburgh coal bed resource areas and attributed with original resource values (millions of short tons) in aggregated reporting categories as described in USGS Circular 891. The file has been generalized from detailed geologic coverages found elsewhere in Professional Paper 1625-C.

This layer represents 5-year relative counts of wildlife carcasses collected by Idaho Transportation Department (ITD) personnel (2008-2012) or reported by the general public (2012) on or adjacent to state highway system (major) routes. To obtain relative counts, the 5-year total counts per mile, which included all wildlife species observed, were divided by the maximum observed calue (98) to give a relative 0-1 risk score. Total counts, which include all wildlife species observed, along with carnivore counts, which include only black bears, grizzly bears, mountain lions, and wolves, are provided. Counts were derived by identifying the nearest mile marker to each carcass point location, then counting the frequency...

This USGS data release contains station and laboratory method information and geospatial information, as well as concentration results for inorganic and organic compounds and bioluminescent yeast estrogen screen and transgenic zebrafish embryo estrogren bioassay, analyzed at 38 sites in 25 states as part of the Chemical Mixtures and Environmental Effects Pilot Study, 2012-2014.

This dataset contains polygons representing deposits of hyaloclastic debris that were generated between about 3.5 and 3.0 million years ago when a series of basaltic lava flows entered the canyon of the ancestral Columbia River. The lava flows were erupted from volcanoes in the area of the Hood River graben of McClaughry and others (2012), generally have low-potassium tholeiitic basalt composition, and were part of a widespread pulse of mafic volcanism in the northern Oregon Cascade Range that occurred between about 4.4 and 2.1 million years ago (Conrey and others, 1996). Lava flows that entered the ancestral Columbia River were rapidly chilled and fragmented during interaction with water (Trimble, 1963, Swanson,...
