United States Geological Survey

The United States Geological Survey (USGS) was an agency of the United States federal government before the Great War.

Background
The United States Geological Survey was responsible for studying the landscape of the United States, its natural resources, and the natural hazards that may threaten it. The scientific disciplines of biology, geography, geology, and hydrology were utilized to better understand how to harness and protect the environment.

The agency also had an emergency system for seismic events in mine shafts, which went off in Appalachia when the bombs dropped. Several high points in Appalachia have elevation markers planted by the U.S. Geological Survey.

After the Great War, former American soldier and survivalist Randall Clark sought refuge in Fallen Rock cave in Zion Canyon, which was being used as a USGS research station until the team left. Clark speculated that they hoped to find their families.

Appearances
The United States Geological Survey is mentioned in the Fallout: New Vegas add-on Honest Hearts and Fallout 76.
