Hidden Valley

 is located in what is apparently an abandoned military establishment, there exists 4 bunkers riddled with anti-war graffiti. The area is nestled between hills and rocks, the main access being via a road near Sloan. Additionally, there are small side-paths, at least one of which heavily inhabited by bark scorpions and the occasional Giant Radscorpion when going in the direction of Scorpion Gulch nearby.

Upon entering each bunker, the player sees an empty room with a locked door and intercom on the opposite side. The locked doors are of varying difficulty. The easy door is confirmed to contain a hundred 5mm rounds. The average door hides a pair of Mini Nukes. In one bunker, however, there is also a journal sitting on a crate, along with a sack with some fruit and other edibles in it. The journal reads, "This location looks like it might make a good safehouse. Warm, dry, and some sort of crazy natural phenomenon at night should keep the predators away. I'd love to start getting set up, but there are a few nearby points of interest I need to gather intel on first. Not sure how long that'll take." At the back of this bunker, there is a hard door that, with a bit of determined rubble climbing, holds 3 ammo boxes, another Mini Nuke and some scrap. The fourth bunker is home to the Brotherhood of Steel.

During the night, vicious sand storms rage around the bunkers, which are defense mechanisms the Brotherhood uses to hide their bunker.

Description
In what is apparently an abandoned military establishment, there exists 4 bunkers riddled with anti-war graffiti. The area is nestled between hills and rocks, the main access being via a road. Additionally, there are small side-paths at least one of which heavily inhabited by bugs.

Upon entering each bunker, the player sees an empty room with a locked door and intercom on the opposite side. The locked doors are of varying difficulty. The easy door contains 100 5mm rounds. The average one contains rubble. In one there is also a journal sitting on crate,along with some fruit and other edibles in it.

This is also the location where you will meet the Brotherhood of Steel. They maintain a bunker which is marked by a small broken tree stump directly on top of the dome.

Note: If you have discovered the two dead Brotherhood of Steel Paladins at the REPCONN facility (on the third floor)or the one near moe near Black Mountain and took the note they were carrying, you can say the password to the intercom of the facility with the Very Hard lock or by having follower Veronica Santangelo with you. You can also gain access through the quest Wild Card: Side Bets.

There are two very hard locked doors in two of the bunkers. Behind one is also rubble. Behind the other one in the entrance to the Brotherhood of Steel bunker, where an explosive collar is placed upon the Courier's neck.

If you are looking for a free set of the Brotherhood's armor right next to where the elders room is is 3 rooms and one of them contains power armor and helmet along with a super sledge, plasma rifle, and plasma pistol. They are illegal to take and still needs power armor training.

The quests: Still in the Dark and Eyesight to the Blind can be activated here.

Glitches
When you are in the BoS Bunker you can help Scribe Ibsen isolate a virus in the database. It is possible that using the Science check causes a glitch that leaves you unable to finish the task. Make sure to talk to Ibsen any time the virus jumps and you should be fine.
