Deep hard slab avalanches with depths to five feet continue to be a serious avalanche hazard. These low probability/high consequence slides are more likely to be triggered where a weak layer of faceted snow that formed in December is less than three feet below the snow surface. Large triggers, such as snowmobiles or cornice failures, are more likely to trigger one of these large destructive avalanches.
