Observer Comments

Skied off the top of Marmot Ridge onto the N face. Started skiing right of the fall-line on one of those spiney ridges, and then cut skiers left to get on top of it, then the storm slab released. A section broke out, was not deep enough to carry me. I then continued cutting and another storm slab released. Avalanches stopped before the end of the couloir / apron.
