Mammoth Rock BowlObservations
Significant natural avalanche (likely wind slab) in Mammoth Rock Bowl that ran essentially the full path (around 1100-1200 vertical feet). The avalanche ran over both bluffs and was within 30-50 feet of one of the normal skin tracks up to Mammoth Rock. I could not see the crown of the avalanche as it was obscured by snow/wind, but I'm assuming it ran from the Sherwin ridge where the bowl typically gets wind loaded. Certainly a large D3 avalanche. I haven't seen it run this far in years.
