Comments

Skier remote triggered slide. Group of 5 skied from the base of the climb up fossil mountain, just east of perception pass. Avalanche was triggered remotely from one of the skiers. The slide was very slow due to the angle of the slope being so low.

Our group did not notice the slide until we got down to the lake and another group of skiers notified us. Thanks to the other group for getting the photos for us!

Stay safe!
