Comments

A group of three was heading through the trees on a steep north facing slope. The first skier triggered the avalanche. Luckily, he was not caught up in it or he would have tumbled over some rocks. It was a small 3.5' slab slide. The crown was around 15-20' and the runout was around 80'. The weak layer was the rocks beneath the slab. No one was hurt.

Forecaster comment: the weak layer was probably faceted snow near the ground in the rocky terrain (similar to most other recent slides on that aspect and elevation)
