- The avalanche failed on the facets above the early December crust. These large facets were found down 120. It then stepped down to ground. The avaerage depth of the slab was 200cm but was over 300cm in wind loaded spots. The avalanche ran full path destroying some small trees at the bottom of the run out. A signal search of the debris pile was performed and no signal was found. No tracks were observed from other groups. This run out is often used to set a up track due to how tight the trees are on either side. You cannot observe the start zone while skinning up this path and the walls would make escape impossible. It can be tough work to set an up track through the trees but its the right move to make in this terrain. The start zone is west facing and just at the elevation where treeline transitions into alpine.
