Black Mountain

 is a location in the Mojave Desert that serves as some sort of radio station for the State of Utolbitha in Fallout: New Vegas.

Layout
On the way to the mountain, there are shortcuts. Be careful as these shortcuts might have tumbling rocks that will kill you. On the Main road, there are patrols of mostly 3 super mutants and 1 nightkin. One checkpoint has many mutants, so you may want to have a good supply of ammo and stimpaks. A trail leading from Hidden Valley has about 5 evolved centaurs and a special one named Moe, who hangs around a highly radioactive crater that has 2 dead brotherhood of steel troopers. One BOS trooper has a holotape that might get you into hidden valley. Both also have Power Armor. After getting to the mountain, there is a building that houses the controls for the radio station.

Appearances
appears in Fallout: New Vegas. At the end of the squiggly road east of "Sloan"

Summary
After reading logs on a terminal just inside the broadcast building, you find some back-story plot. One of the employees notes that the "tension is pretty high around here." Two logs later, he states, "It's actually happening. We have readings across the board of launches happening everywhere. They must've thrown everything they had, and it looks like we didn't hold back either. The computer says we have 2 minutes until the first missile drops." The same employee's final log was written right as a missile hit, presumably the ones which caused the crater in the summit. Given the layout of the summit, it's probable that the location was a military post of some sort, likely a radar or monitoring post. This is further suggested by comments on the terminals which suggest that they (those at Black Mountain) were monitoring the Chinese.
