Human: Compose a short description of a foreboding setting outside a wilderness cave with unsteady ground. a spooky wilderness ravine with lichen and pines. Assistant: 
Lichen mottles the surface of boulders forming the bluff, their surface sheared of snow by gusting winds blowing up from the gorge below. The flurries are buffered to the northwest by a dense forest of pines that stand dark and seemingly impenetrable. A trail forms and winds away to the northeast, as though fleeing the maw of the shadowy ravine. It soon disappears, lost in a vast expanse of blizzard-swept tundra.
