This data release contains three 10-meter resolution GeoTIFFs representing 10-meter (35-foot), 30-meter (100-foot) and 90-meter (300-foot) riparian buffer zones along shorelines, rivers, streams, and other lotic (flowing) water features. The layers are binary, where the value of each cell represents the presence or absence of the buffer zone. In addition, the data release contains shapefile layers that document the extent of corrections that were made to the data to address errors in the stream network (see processing steps section for more details). The methodology combines various fine-scale input layers, including a 1:24k stream network and Chesapeake Bay 1-meter resolution Land Use/Land Cover to approximate...

Death Valley National Park, California. Furnace Creek Formation at the north end of the Black Mountains. View is southwest and west of Zabriskie Point, an overlook by Highway 190 about 3 miles up Furnace Creek Wash from Furnace Creek Inn. The base of the Furnace Creek Formation is at the topographic break between the badlands and the rougher, higher ground in the distance on the left. Light-colored playa beds about 2,500 feet thick extend to the base of a conglomerate which forms the dark cliff at the right. The beds are dipping to the right (north) into the Texas Spring Syncline. The center of the photograph looks west across Death Valley to the Panamint Range at Aguereberry Point; Tucki Mountain on the right....

Data consist of presence / absence records of planktic foraminifer species from 5 core samples at 3 localities in southeast Florida. Samples are placed in biostratigraphic zones and ages are estimated from calibrated first and last appearances of select taxa.

A hydrodynamic and water-quality model (CE-QUAL-W2) was developed of a 21-mile reach of the upper Illinois River including a 3-mile reach of a major tributary, the Fox River. The CE-QUAL-W2 model is 2-dimensional in the vertical and longitudinal directions and averaged over the lateral direction. Continuous water quality and streamgage data provided time-series data for model boundary conditions. Discrete velocity, cross-section area, and temperature profiles at several locations within the study reach provided model calibration data. The model was calibrated to 2021 and 2022 observed data and validated with 2020 data. Model output consisted of 2-dimensional, laterally averaged hydrodynamic and water-temperature...

Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 40-year period (1984-2023). The Landsat BA product was consolidated into a suite of annual BA products, which in-turn were used to calculate a series of contemporary fire history metrics (30 m resolution). Fire history metrics included: (1) fire frequency (FRQ), (2) time since last burn (TSLB) and (3) year of last burn (YLB), (4) longest fire-free interval (LFFI), and (5) average fire interval length (FIL). All metrics...

This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

This data release (version 2.0, July 2021) consists of a Microsoft® Access database that contains groundwater withdrawal estimates from 1913 to 2016 for the Death Valley regional groundwater flow system (DVRFS). The four tables in the database also are provided as individual comma-separated values (CSV) files. This version (2.0) of the data release contains the most current version of the database and supersedes all previous versions. A total of about 41,000 acre-ft of groundwater were withdrawn from DVRFS in 2016 of which 51 percent was used for irrigation, 20 percent for domestic, and 27 percent for public supply, commercial, and mining activities. The total groundwater withdrawals for Pahrump Valley (hydrographic...

Down a small side canyon into the Blackfoot River canyon in sec. 10, T. 3S., R. 38 E. Paradise Valley quadrangle. The valley flow of basalt wedges out against the Salt Lake formation; note the bedding and "badland" erosion. Bingham County, Idaho. August 1925. Figure 8, in U.S.Geological Survey Professional Paper 238. 1952.

Death Valley National Park, California. Fractured cobble conglomerate in the Titus Canyon(?) Formation of Stock and Bode (1935). The fractures extend through the cobbles, and some cross from one cobble to another. They are oriented at right angles to the bedding, which approximately parallels the elongation of the cobbles. Displacements along the fractures are mostly less than a quarter of an inch. Circa 1960. Figure 41, U.S. Geological Survey Professional Paper 494-A.

Index card: In Marble Canyon at 27 Mile Rapids. Channel in erosion surface at top of Lower Slope Unit (Watahomigi Formation) in Supai Group, at base of Manakacha cliff unit. Woman at left for scale. Grand Canyon National Park. Coconino County, Arizona. 1967. (Similar to E.D. McKee no. 330). Similar to black and white photograph published as Figure H3-B, U.S. Geological Survey Professional paper 1173.

Boulder County, Colorado, ca. 1951. Published as figure 9 in U. S, Geological Survey Professional Paper 274-B. 1955.

Shenandoah National Park, Virginia. Columnar jointing in greenstone. Large column along the Appalachian Trail about 200 feet south of Little Stony Man parking area. The column is cut by cleavage which dips east, away from the observer. The segment of the coluiai above each cleavage plane is offset westward from the segment beneath as a result of movement during formation of the cleavage. Column is approximately 2 feet in diameter.

This data release consists of a Microsoft® Access database that contains groundwater withdrawal estimates from known and approximate well locations (withdrawal points) in the Death Valley regional groundwater flow system (DVRFS) to support a regional, three-dimensional, transient groundwater flow model (Belcher and others, 2017; Halford and Jackson, 2020). The database provides information for each withdrawal point including estimated location and completion interval (Moreo and others, 2003). Groundwater withdrawal estimates for each withdrawal point have been compiled by water use and year. Uncertainty was assigned to the annual withdrawal values based on the use and method of estimation (Moreo and others, 2003)....
