Skiers triggered this avalanche on a north-facing slope near the Anger Lake basin.  The crown was 4-18 inches deep and propagated the entire width of the gully ~40 feet and ran the entire length of the gully ~500 vertical feet. The skier was able to ski out of the avalanche right as it broke and was not carried. Photo: Anonymous

New snow avalanche Northern Bridgers

Date
Activity
Skiing

After skiing two laps on East facing terrain two basins north of Anger Lake basin and seeing no significant signs of instability, we descended into a north facing gully around 8,200ft and triggered an avalanche on the new snow/old crust interface. The crown was 4-18 inches deep and propagated the entire width of the gully ~40 feet and ran the entire length of the gully ~500 vertical feet. I was able to ski out of the avalanche right as it broke and was not carried.
