The Rocky Mountains, or Rockies for short, are a mountain range in North America.


Before the war, Dutch Wharton, the senior vice president of Hornwright Industrial's corporate engagement department suggested to CEO Daniel Hornwright that they put the Motherlode project on hold in favor of a more lucrative endeavor that would result in the company becoming "the premier industrial company east of the Rockies."[1]

In 2103, Paladin Leila Rahmani led the First Expeditionary Force across the country, from Lost Hills to Appalachia, with goals of re-establishing contact with the lost chapter of the Brotherhood. A message records the loss of contact with the group after they crossed the mountain range.[2]

After traveling with the Chosen One, Marcus ventured into the Rockies in search of more first generation super mutants like him. He eventually returned with a small flock, founding a town on Black Mountain in the Mojave Wasteland.[3]


The Rocky Mountains are the second largest mountain chain in North America, stretching more than 2,000 miles from Canada to New Mexico.


The Rocky Mountains are mentioned in Fallout: New Vegas and appear on the world maps of Fallout Tactics. They are also mentioned in Fallout 76 and in the One Wasteland For All update.

Behind the scenes

The Rocky Mountain Arsenal was a planned location within Van Buren.

  2. Encrypted broadcasts: "First Expeditionary Force, this is L-H with a recorded Priority Gamma message.
    Papa Romeo missed the last four check-ins. No contact since crossing the Rockies. Scribes estimate unit position in the vicinity of Lincoln. Orders are to re-establish comms with L-H ASAP and provide a full report of whereabouts and activities since last communication. Acknowledge on coded channel two three."
  3. The Courier: "Tell me more about the tribal."
    Marcus: "We were looking for a GECK to save the village of Arroyo. Eventually, we did. Nuked an oil rig in the process. We went separate ways after that. I went east into the Rockies, looking for other mutants like myself. Don't know what happened to my friend. I've got a feeling it turned out all right in the end."
