The photo shows the Klamath River following the 2022 McKinney Fire, with burned areas visible along the distant ridgeline and a debris fan in the foreground near the confluence of Little Humbug Creek and the Klamath River. The photo documents sediment and debris deposited from burned landscapes into the river corridor following wildfire and storm runoff.

In June 2022, Mendenhall Fellow Sabine Loos (Research Civil Engineer in the Geological Hazards Science Center) presented a seminar to USGS's Earthquake Science Center at Moffett Field, CA, where Max Schneider (Research Statistician) works as a Mendenhall Fellow.

Drought Intensity Map compiled by the U.S. Drought Monitor for the area of NOAA's Colorado River Basin River Forecast Center, which includes part of the Great Basin drainage area in western Utah, for April 19, 2024.

A helicopter rigged with an airborne geophysical survey collecting equipment. Information collected during these surveys can help with studying critical mineral resources, natural hazards and groundwater potential. A cow is here too.

A low-flying helicopter towing a geophysical device collects scientific data on groundwater and geology. Information collected during these surveys can help with studying critical mineral resources, natural hazards and groundwater potential.

RestoreNet treatments include soil pits and connectivity modifiers (ConMods), seen here at a RestoreNet site in the Sonoran Desert.

A map showing North America's tropical-to-temperate transition zone. Red, orange, and yellow depict the more tropical zones, and blues depict the more temperate zones, based on to the coldest recorded temperature for each area between 1980 and 2009.

UAS Research Center's BisonCore Project, augments an autonomous rover to avoid running into obstacles. Shown in picture; user set waypoint (2) that runs over a curb/barrier. CDA engaged and navigated south avoiding, and seeking a path around, the curb.

 Winter temperature extremes control the distributions of subtropical fishes. Common snook (Centropomus undecimalis), aggregate at a spring in northern Florida during winter. Snook are warm saltwater game fish, common in Florida, that have been moving further northward as extreme cold spells become less frequent and less intense.

The USGS landslide team monitors and continues to update the hazard map models based on data collected in burn areas. This information improves future models and provides better hazard assessments used by officials for emergency response and decision making. Many of the steep hillsides burned and denuded in California fires repel water rather than soak it in.

Lahontan cutthroat trout (Oncorhynchus clarkii henshawi) is a federally listed threatened species. Ninety-seven percent of their range are small headwater streams in the Great Basin of North America.

This report includes five chapters. Chapter A (Mason, Knight, and others, 2020) is a summary of this multichapter volume and briefly describes the study area. Chapter B (Mason, Bills, and Macy, 2020) describes the geology and hydrology of the Truxton basin and Hualapai Plateau.
