Avalanche: Hells Canyon

A sizeable wet slide appears to have run yesterday afternoon, in Hells canyon. Not clear if this was skier triggered or natural. Deposition about 300 feet in length, 2 to 5 feet deep, leaving a hard ice bed surface, and even scouring a small sidewall on the right. 3rd photo, I threw a ski pole down into the debris for reference. Note the old wet debris on the left, with a blanket of fresh snow.
