After the Great War, Yucca became abandoned by humans and highly radioactive because of its contents left unchecked. No prospector dares to enter Yucca without a good radiation suit.

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

Appearances
Yucca Mountain is mentioned 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 was canceled in 2009 by the Obama administration.
