Yucca Mountain

Yucca Mountain is a mountain in Nevada, near the boarder of California, 100 miles northwest of New Vegas.

Background
Yucca Mountain, at some point before the Great War, became a nuclear waste repository where spent fuel rods and high level nuclear waste was dumped and locked away from public harm. After the Great War, Yucca became abandoned by humans and its highly radioactive contents left unchecked and left to fester for hundreds of years. No good prospector with any wits dares to enter Yucca without a good radiation suit and a lot of courage.

Yucca Mountain may also be inhabited by large mutated creatures, as in Mr. RADical's journal, the author mentions seeing "something big" moving down its tunnel.

Appearances
Yucca Mountain is mentioned only in Fallout: New Vegas.

Behind the scenes
In the real-world, Yucca Mountain was to become a nuclear waste repository under the Bush administration, but the project was canceled in 2009 by the Obama administration.
