Notes

Skiers triggered this avalanche in dense trees while ascending Mt. Ellis. From the email: "While subsequently skiing up through dense trees climbing to the north to attempt to reach the mid section of the going-home chute, a medium-size bowl-shaped opening in the trees released a soft slab just as we were entering the opening. The crown was ~24” deep and ~80-100’ across. Total snow depth in that area was less than three feet. The avalanche ran probably 500 vertical feet down a shallow gully. Neither my partner nor I where caught but way too close for comfort."
