Human: Produce a detailed written description of a spooky scene outside a wilderness canyon with streams, holes, a fissure, and lichens. Assistant: 
Glowing lichens, high above, cast a dim illumination on the gushing streams below. Water cascades in frothy veils and powerful sprays from large holes in the sides of the fissure. The torrent swells to several feet in depth, churning mightily as it tumbles away.
