Human: Write a detailed description of a serene scene outside a wilderness canyon with ice and a glacial tributary. Assistant: 
A canyon tumbles down from the mountains to the northeast into the glacial valley. Perhaps at one time it was carved by the erosive action of flowing water. Now it is a glacial tributary, a river of ice moving slowly downward toward the huge glacier locked in Gossamer Valley. The canyon is several hundred feet wide, and the ice provides a fairly flat footing for those wishing to explore the canyon's origins.
