After an excellent lap in Hidden Bowl of boot top powder from top to bottom, we climbed back to the ridge separating Corral 2 and 3. A ski cut into Corral 2 created a large crack from the bolder 20m away from the top of the run. It ran 12m up and lookers left and 15 m down and right. A second ski cut into Corral 3 produced a skier remote from 40m away in a thin area. Crown was 40-60cm thick, 200m wide and ran for about 350+m taking out the whole bowl. A small portion slid to ground. We skied the ridge and then the circumference of the debris field and no ski tracks were noted other than ours.
