Saw this avalanche on the skiers left side of the Wilson Chutes it obviously went into old snow and by the looks of the crown and its lower elevation E-SE facing aspect I suspect it went on facets or depth hoar close to the ground. The slide looked to occur later in the storm, the crown and bed surface were pretty clean. The interesting thing about this slide is the aspect' I haven't seen much evidence of SE facing slopes breaking into old snow at the ground, that being said it was in a shallow snow-pack area with multiple weak layers.
