Sierra Nevada

The Sierra Nevada mountain range is a prominent landmark in New California, and has been the site of many faction-oriented conflicts since the bombs dropped.

Background
The lower region of the Sierra Nevada, ending at Junktown and overlooking Shady Sands, is present in Fallout, and is where the elusive Vault 13 can be discovered. In Fallout 2, the mountain range spans the entire eastern section of the map, and contains the town of Modoc as well as the city of New Reno. Aaron Kimball mentions the mountains in his speech at the Hoover Dam, referencing the Sequoia trees that are indigenous to the area.

In the months before the Brotherhood First Expeditionary Force arrived at Appalachia, Matthew Thornberry rescued several captured Brotherhood members from hostile raiders in these mountains.

After being decimated by the Brotherhood of Steel, many of the surviving Vipers fled into these mountains and beyond, into the Mojave Wasteland where they would remain a threat for decades to come.
