Make a short description of a rocky wilderness setting with a narrow path and algae stains.

A narrow path hugs the western edge of the rocky valley, sloping sharply as it curves around to connect the upper edge of the basin with the rim above. Old green algae stains the edges of the trail, retaining its color even well after death. Numerous rocks are half sunk into the walls, stacked haphazardly on each other and anchored with dirt.
