This avalanche fractured on a rollover on a steeper NE aspect. We anticipated a possible fracture so we had one skier ski cut across the top of the rollover. Our planned route was to ski around this area and drop down a treed ridge. The skier triggered a surface slab that appeared to be all new storm snow, less than 1 ft. in height. We noticed some older cornice breaks in the area but we did not see any signs of natural activity.
