United States Geological Survey

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

Background
The U.S. Geological Survey placed survey markers at varying elevations throughout the former state of West Virginia, of which six can still be found. The agency had an emergency system for seismic events in mine shafts, which went off in Appalachia when the bombs dropped.

After the Great War, former American soldier and survivalist Randall Clark found refuge in Fallen Rock Cave in Zion Canyon, which had been 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.
