Human: Write a description of a risky scene outside a gorge with debris, a river, rock falls, and spruce. Assistant: 
Following the narrow gorge, the path becomes arduous as it climbs over rock falls and between tangles of river debris. High upon the canyon rim, abundant pine, fir, and spruce flourish but grow more sparse as they descend upon the canyon walls until only the occasional doughty bush or tenacious pine cling precariously to the mountainside.
