This very small avalanche was triggered by a snowmobiler today (Monday, March 11) on the north side of Fisher Peak. It was steep and shallow and is indicative of  potentially triggering deeper slabs from rocky, thin areas. Photo: GNFAC

This avalanche was triggered by a snowboarder on Friday (March 8). Small facets under the new snow were reactive for a short period of time. Photo: GNFAC

This deep slab avalanche appeared to have been triggered by skiers on Saturday (3/9) or Sunday (3/10). It shows the type of terrain to avoid in order to avoid triggering a big avalanche: Variable snow depth, complex and rocky. Photo: D. Sandberg

On Saturday (3/9) skiers observed multiple large natural avalanche crowns near Wilson Peak and Dudley creek in the northern Madison Range. They appeared to break on weak layers near the bottom of the snowpack. Photo: G. Egnew

This slide was triggered on a steep (40 deg) southeast facing slope at Round Lake outside Cooke City. It failed 8" deep on a layer of graupel and small facets. An adjacent hill slid at the same depth beforehand. This layer is not on most slopes, but as this slide shows it is on some. Doug was in the area and dug a pit in the crown soon after it was triggered. Photo: J. Fritz

This large natural avalanche occurred in the Absaroka Mountain Range outside of Paradise Valley. The slide broke hundreds of feet wide and 2-4' deep. It was likely triggered by a falling cornice. Notice the long distance it ran. This is a good reminder that low angle slopes can still be avalanche terrain. Always pay attention to the terrain above you. Photo: J. Negri

This slide on the NE face of Blackmore was triggered by the second skier. It was 8-12" deep and 100' wide and likely failed on small faceted crystals underneath the new snow. No one was caught. Going one at a time was good travel behavior that can save our lives when things go wrong.
