Human: Make a concise location description of a foreboding scene outside a wilderness canyon with a rock wall, rocks, wrappers, ladder, and stones. Assistant: 
Rubble surrounds a long-expired fire pit. Ever-higher piles of rocks to the west block the way forward. Short of excavation, there is no way to go further. To the east is a high rock wall that looks very difficult to climb except for the rope ladder that provides a way out. Years of non-use have worn down what may have once been a makeshift camp. A few discarded ration wrappers lie decaying between and under two large stones.
