Human: Generate for me a description of a mountain wilderness setting with a rock wall, a ledge, ice, and a footpath. Assistant: 
In the distant past, some cataclysmic event sheered off a section of the mountain to create a smooth rock wall. A narrow ledge, the result of a natural fault in the rock face, serves as a footpath up the mountain. Ice covering the ledge in a thick slippery sheet makes for dangerous travel.
