This avalanche was skier triggered. The black line indicates where it broke. The red line is incorrect: she came down the next gully to the left. Photo: GNFAC

This avalanche initially broke 20 inches deep then produced an avalnche 4-6 ft deep. Although this avalanche was intentionally triggered at a ski area, it represents a likely scenario in the backcountry. Photo: MLB Ski Patrol
This avalanche broke 18 inches deep and 75 feet wide on a layer of near surface facets that formed 1-2 weeks ago. It occurred on an E aspect around 9200 ft. It was triggered from low angle terrain about 30 feet away from the crown. Remotely triggered avalanches are a clear sign of very unstable conditions. Photo: M. Young
This natural avalanche occurred just above the summer trailhead for Sacajawea Peak in the norther Bridger Range. Photo: D. Pogge
The avalanche path is more obvious from a distance, but not from the road. Daisy Pass is up to the road to the left of the picture. Due to a reloading of the slope and a HIGH avalanche danger we were unable to hike up and investigate the snowpack. We are unsure if this slide was a natural or human triggered. The crown was likely at the top of the slope (estimated to be 600 feet vertical), but we could not confirm this. Photo: GNFAC
The victim was buried on the road where the skier is standing. The avalanche hit him as he turned his sled around. He was buried under approx 4 feet of snow. Photo: GNFAC
This photo is looking below the road. The two skiers are in the spots where the snowmobilers were partially buried (arm was sticking out of the snow for each). Photo: GNFAC
A snowmobier was caught and killed while riding on the road leading to Daisy Pass. The avalanche came down the slope above the words "Accident Site". The Pass is located up the road to the left. The slide that buried the rider likely released naturally, catching him as he attempted to turn around at the bottom of the path. Three other riders were also partially buried, two with just their arms sticking out of the snow. The three riders that were partially buried escaped unharmed. Photo GNFAC
