These spatial data represent alluvial deposits of the Colorado River and tributary deposits adjacent to the Colorado River in Grand Canyon National Park. The map covers the river corridor from Lees Ferry, Arizona to the confluence with Diamond Creek 225 miles (362 km) downstream. The alluvial deposits of the Colorado River are mapped as either sand or gravel based on surface composition and the sa

This data set was collected as part of structured decision-making workshops designed to build a Bayesian Decision Network of prescribed fire in high marshes of the Gulf of Mexico. As part of a formal elicitation process for expert judgment, workshop participants independently created conditional probability tables based on a conceptual model of prescribed fire in high marsh ecosystems. Following t

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered conventional and continuous oil and gas resources in in the Lewis Shale of the Southwestern Wyoming Province, Wyoming and Colorado. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment

In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S Geological Survey (USGS) in cooperation with the NCDOT conducted a pre-construction light detection and ranging (lidar) survey of the streambanks within a on

This digital dataset includes 266 samples from 208 groundwater wells and 481 samples of produced water from 408 sites (including 199 wells) located within 3 miles of the Edison, Mountain View and Ant Hill Oil Fields in Kern County, California. Historical geochemistry data were compiled from multiple data sources for selected water-quality indicators, major and minor ions, nutrients, trace elements

This data release provides forest structure information including basal area and stem density by genus and mortality status for overstory and sapling trees in 149 plots in Whiskeytown National Recreation area in California, USA. The data includes forest structure measurements taken before and after the 2018 Carr Fire, a nearly 93,000 hectare wildfire.

Raw aerial photography, orthorectified imagery, point cloud data, and digital elevation models (DEMs) for Whiskeytown National Recreation Area (NRA) following the Carr Fire. Sites within the NRA include: Lower Crystal Creek, Tower House, Grizzly Gulch, Boulder Creek South Shore and Conifer, Brandy Creek Camp, Shasta Divide, Paige Bar (North, NEED Camp, East, and Southeast), Chinese Laundry, and Co

This dataset is the fourth installment of a yearly connectivity update for forested habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, WI and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin boundary in the so

This dataset is the fourth installment of a yearly connectivity update for open habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, WI and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin boundary in the south,

A ground-based magnetic survey was conducted in Glastonbury, Connecticut. Magnetic surveys are passive, non-contact, surface geophysical methods that measure the total ambient magnetic field. The magnetic survey utilized a Geometrics G-858 MagMapper with dual cesium vapor magnetometers and a GEM Systems Base Station. Sixteen survey profiles, totaling 7 linear kilometers in length, were carried out

This data release contains a three-dimensional groundwater flow model with example applications using MODFLOW-2000. The calibrated model is able to simulate observed decadal-scale climate-driven fluctuations in the groundwater system as well as observed shorter-term pumping-related fluctuations. Example model simulations show that the timing and location of the effects of groundwater pumping vary
