Comments
Cornice drop from the Fist, triggered a slab, extended into edge of one of the Tryst chute runs. Crown perhaps from separate or sympathetically triggered avalanche extended all the way around the bowl and into the trees by Tent Ridge. Occurred after the storm snow as the crown was still crisp and not blown in. Lowest crown close to the lake was approx 80cms thick, debris ran to the trees across the headwaters of the lake.
