Fallout: New Vegas locations project
Dead Horses camp
You must travel through a canyon to reach this location. Be aware of the beartraps in the water that the Dead Horses had set up to keep the White Legs out, as those can do a fair amount of damage. This location consists of Angel Cave.
Directly opposite to the entrance to Angel Cave you will find what looks to be a ramp of stone, if you climb your way on top of this 'ramp' you will come across a skeleton.
If you have the trait Wild Wasteland, upon entering the camp, a Dead Horses tribal named Two-Bears-High-Fiving will rush out of the Angel Cave and then head back in where he will stay. This refers to a mod from New Vegas Nexus that makes it optional to select the dialogue "Two bears high fiving" during the beginning of Fallout: New Vegas, while being tested by Doc Mitchell.
This camp will be empty if you have completed Flight from Zion.
