Comments
Cornice triggered new wind drifted snow avalanche. This wasn't very deep and wouldn't have been deep enough to bury a person. It appears it was natural ( but being such a busy location) it could have been skier initiated. Smaller avalanche on lookers left in photo ran 200'.
First photo-Larger further running cornice triggered avalanche
Second photo- smaller avalanche on lookers left of photo (debris stopped behind the tree island).
