Human: Produce a detailed written description of a secluded wilderness scene with a tunnel, tree root, and floor. Assistant: 
Pine logs, once part of the forest that grew down to the lake's shore, brace the walls and ceiling in a pattern of large X's behind which the earthen walls can be seen. Dirt floors and walls release no dust when touched, and though firmly packed, absorb most of the sounds of movement. A good-sized tree root runs across the floor of the tunnel, the builders probably having decided to step over it rather than hack it out and have to fill in the resultant hole.
