Human: Please generate a brief description of a spooky wilderness setting with a swamp, stones, rocks, and a ledge. Assistant: 
Lakebed rocks become more prominent along this offshoot of the trail, as though more recently maintained. The dark rich stones sport a mottled hue speared with alabaster veins. The pass meanders east a short distance before a steep ledge cuts it off, descending into a deep gully and down to the edge of a morose-looking swamp. Forbidding scents waft outward, festooning its banks like a decorative collar.
