Timber (Grass and Understory)

Upper elevations across the fire area are dominated by aspen and timber fuel models with heavy dead and bug kill, with many patches of rock that help break up continuity. Lower elevations are dominated by grass and sagebrush with timber stringers consisting of juniper and aspen. The fire travels through sparse fuels, continuing its progression, therefore increasing in size. Steep and rocky terrain, weather, and current fire behavior is a hazard to firefighters.
