Human: Write a detailed description of a dreary scene outside a mountain with rocks, puddles, and a fern. Assistant: 
Thin trickles run down from the southwestern end of the trail, collecting the red volcanic dust until it pools in small puddles of soiled water. A pale-green fern sprouts from a moistened patch of soil, enriched by a spray of fine mist blown in from the upward path. A dewy moisture clings to all surfaces, leaving the rocks slick and the soil slightly muddy.
