This avalanche was triggered with explosives by the Bridger Bowl Ski Patrol. In the foreground is the Bridger Chairlift. This avalanche is a major warning sign that conditions in the backcountry are unstable. Photo: GNFAC

GNFAC Avalanche Forecast for Tue Mar 27, 2012
Snowpack and Avalanche Discussion
Backcountry conditions will change hourly today, and so will the avalanche problems and avalanche danger. Any slope that faced the sun and got wet is now capped with a thick ice crust. The new snow will be bonded to this crust, but near the ridgetops isolated wind slabs could be triggered this morning. As the day warms, the new snow will easily sluff as wet, loose avalanches. If it gets warm enough to melt the underlying crust, the wet snow avalanche danger will rapidly increase too.
The pic shows the slide on Cedar that was observed yesterday (3/25). The slide on the right occurred about a week ago and the bed surface has had more time to melt out. The one on the left occurred supposedly sometime yesterday morning. Photo: C, Babineau-Z

This avalanche likely occured on midday Saturday (3/23) on a north facing slope off Miller Ridge at 8,500'. Photo: A. Steckmest
These wet slab avalanches broke today (Mon, 3/23) during the warm, well-above freezing temperatures. The avalanche on the left broke above the slide that was triggered by a snowmobiler on Friday. Weak snow at the ground quickly becomes unstable when water hits it. Photo: GNFAC

This avalanche released naturally outside Bridger Bowl's boundary. Above freezing temperatures allowed water to percolate down to the weak facets at the ground where the avalanche released from. Photo: GNFAC
