A group of NCR soldiers were sent by a New California Republic survey team to clear the old hiking trails and establish an observation base. The soldiers were under the command of Sergeant Banner, who efficiently led the reclamation of the area. They immediately faced difficulties requisitioning a radio and proper supplies, such as Cateye.
On the fifth day of this effort, a soldier named Jackson began to report strange noises like howling in the darkness. Banner dismissed these reports early on, blaming it on the wind, or even a pre-existing condition of Jackson's until he himself started hearing splashes down in the water. In their rock blasting to create the trails, they uncovered a cave that led straight into the mountain. The sergeant was not informed of any caves by the survey team and blamed them for not catching this during the initial survey. A team was sent in, which included Private Halford, to explore the caves.
The peak itself is devoid of NCR soldiers, but is populated with numerous giant rats and several radscorpions. A sleeping mat is near the ham radio emitting the radio signal. However, the nearby cave system, Camp Guardian caves, contains the dead NCR troopers that were stationed at Camp Guardian and the unmarked quest Help for Halford.

- A Sunset Sarsaparilla star bottle cap - Near the radio by the campfire.
