Human: Generate a short description of a cold wilderness setting with ferns and a dry streambed. Assistant: 
Lush green ferns line this hollow in the rock. The soil is thicker here, with the dry bed of a tiny stream, probably carved by flowing rain water, running down from above and disappearing into a dry, cracked basin. Towering stone rises high overhead in every direction, making this hollow uncomfortably cool even though it's protected from the wind.
