Comments
This natural avalanche occurred sometime yesterday afternoon, seemed to be triggered by a natural cornice fall not sure of the weak layer but I think it was new snow only. The slide ran all the way down to the flats and left a large debris pile at the toe. This path has already released a few times this year but this is the biggest I've seen it go this year.
