Geoheritage is a term which lies at the intersection of science, society, and sustainability and is applied to significant geologic features and landforms that have scientific, educational, cultural, economic, and aesthetic value. Many geologic sites have enriched society through the geoheritage values: scientific research and education, cultural significance, economic opportunities, and...

This release of digital geologic map data covers the Niobrara National Scenic River, a 76-mile stretch of river at the northern edge of the Nebraska Sand Hills. The mapped area includes the National Park Service unit of the Niobrara National Scenic River and the adjoining Middle Niobrara Preserve of The Nature Conservancy, and the Fort Niobrara Wildlife Refuge of the U.S. Fish and...

This dataset accompanies publication “Lead isotopes in New England (USA) volcanogenic massive sulfide deposits: implications for metal sources and pre-accretionary tectonostratigraphic terranes”, published in Canadian Journal of Earth Sciences (see 'Related External Resources' section below). The data encompass Pb-isotope analyses of sulfide mineral separates, mainly galena, as well as...

This dataset contains geologic mapping coordinates, and geochemical, geochronologic, and isotopic data collected for shonkinite dikes and zircons from Bobcat Hills, California, USA. See accompanying G-Cubed publication described in the "Larger Work" section of this metadata file for a detailed description of this dataset.

To observe real-time pier scour at three scour-critical sites in Idaho, the U.S. Geological Survey, in cooperation with Idaho Transportation Department, installed and operated fixed real-time (15-minute interval) bed elevation scour sonar sensors at three bridge locations associated with U.S. Geological Survey streamflow gaging stations for water years 2020 through 2022. Observed pier...

This dataset represents 505 campsites along the Colorado River in Grand Canyon with associated debris flow probabilities calculated for approximately a 100-year period (Griffiths and others, 2004) and geomorphic attributes mapped by the U.S. Geological Survey, Southwest Biological Science Center, Grand Canyon Monitoring and Research Center (GCMRC) (Hadley and others, 2018). The campsite...

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...

Between 2011 and 2018, numerous restoration treatments were constructed in the Straight and Braided and Straight Reaches of the Kootenai River in northern Idaho as part of the Kootenai River Habitat Restoration Project. Led by the Kootenai Tribe of Idaho, the project aimed to address a range of anthropogenic impacts inhibiting natural recruitment of the critically endangered Kootenai...

In September and November 2023, the U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, collected geophysical surveys of 5 karst drainage features (sinkholes) in eastern Genesee County, New York, in order to study the nature of the subsurface fill material, bedrock topography, and karst dissolution features. Sites were surveyed using...

This product is a georectified and tonally balanced mosaic of aerial photographs collected in 1938 by the U.S. Bureau of Reclamation along the floodplain of the Colorado River in Mohave Valley region of Arizona, California and Nevada. This dataset is a primary resource for the development of a geologic map showing the floodplain and river channel characteristics along the Colorado River...
