We were downhill tunneling in upper east Willow fork today and found instablity at the small rollover toward the bottom of the slope. The first person in got a section of the slope to release. The density inversion and a rouge telemark skier caused the failure. The avalanche was wider than we first thought. Upon exmaination, we found the crown weaving itself through the aspen trees and bushes a couple hundred feet wide and about a foot to a foot and a half deep! It also sympathetically released a few small pockets totally seperate from the initial slide. The main avalanche didnt run very far because the runout zones slope angle decreased quickly into an aspen grove. I bet some of the steeper slopes went big today?
