Along with its neighbor Hopeville, Ashton was home to several United States Armed Forces nuclear missile bases and silos. In 2077, along with the rest of the world, it was hit by a nuclear arsenal while it launched off its own. Before the Great War, Ashton and Hopeville suffered from occasional earthquakes with many citizens (as described in a terminal entry in a collapsed skyscraper in the canyon) very concerned as to why the military built a missile site near a city that is prone to earthquakes.
Centuries later, it was part of a large community when the Courier opened supply lines to the town. However, they had accidentally detonated a nuclear weapon at Ashton and Hopeville, and the entire city fell silent. Ashton became part of what was known to be the Divide. Even after the Great War, Ashton and Hopeville still suffer from earthquakes.
Ashton is now a wreck of the skeletons of buildings and camps of marked men who have survived the brutality of the Divide. Many ruined elevated highways have collapsed as well as numerous cars littering the area.
Ashton appears only in the Fallout: New Vegas add-on, Lonesome Road.
