There is a hollowed-out rock slightly to the right of the entrance of the cave. Directly inside, Cannibal Johnson is standing in front of a campfire. There is also a bear trap on the ground directly in front of the entryway. Inside his living area is an Enclave footlocker and an unowned bed.
Past the living area, a path leads down into another room, containing the corpses of coyotes, night stalkers, and mole rats. There are also a few pools of "blood" in this same room, which counts as stealing if the Courier drinks from it. Although it appears to be blood, the game treats it as radiation-free water.
- Grognak the Barbarian - On Johnson's bed.
- Mole rat wonder meat - On a cutting board. This is the only place in the Mojave Wasteland where this meat is found.
Cannibal Johnson's cave appears only in Fallout: New Vegas.
Two dead coyotes in the room with the pool of "blood" may re-spawn alive with zero health. [verified]
