The camp is just a small shack on a cliff-side east of Ranger station Echo. There is a Sunset Sarsaparilla star bottle cap next to an empty Sarsaparilla bottle. Across the river, east of this location is a path up the mountain on the other side to an unmarked location inhabited by a large amount of deathclaws, known as the deathclaw promontory.
The Cliffside prospector camp appears only in Fallout: New Vegas.
