If there was even a chance I'd see the two of you again, I'd run outside.”— Randall Clark, January 1st, 2078
Before the war, the cave was used by a United States Geological Survey research team. When the war broke out, they fled, most likely trying to get back to their families. They left behind large amounts of food, which would later prove useful to Randall Clark. After hiking from his disabled truck after the destruction of Salt Lake City, Clark found the cave and stayed there while the radiation outside reached lethal level. The supplies that the research team left behind and the water found in the cave proved invaluable, as Clark was forced to stay in the cave for several months. He soon moved on after the radiation cleared, leaving the cave abandoned.
One entrance to the cave starts as a small, circular room. There are mines and trip-wires connected to rigged shotguns throughout the cave. There are also some boxes of ammunition lying around, often near the shotgun traps. The traps extend throughout the entire cave.
Towards the center main room at the split leads to more mines and shotgun trip wires. There is also a mine hidden behind a teddy bear in the entrance of the central room. In boxes and crates are aid items and ammunition. There is also the Compliance Regulator, a workbench crate and one of the six hidden survivalist caches. There is a terminal with two lengthy diaries on it. Eastwards are more mines and a skeleton with a recharger pistol.
To the very east is an exit to Eastern Virgin with a tripwire and grenade bouquet just before the water. Disarming the grenade bouquet (located at the beginning of the down-sloping exit hallway) requires jumping to reach it. Both exits are close to Angel cave.
- The Compliance Regulator located in the Survivalist's main room, it can be found hidden behind an open wooden box containing ten energy cells and three drained microfusion cells.
- One of the six hidden survivalist caches is here.
- It is one of the first survivalist locations the player character will likely come across. Once cleared of traps, the cave is an ideal base of operations during Honest Hearts, with all three crafting platforms placed right next to each other, and a few containers for storage. However, as with other caves, items stored or dropped may be deleted on the first trip back to the Mojave after completion of Honest Hearts, therefore it will need to be cleared out when traveling between regions.
- There is a hollowed-out rock up the slope to the left after crossing the second bridge.
