Comments
Multiple natural avalanches on Twin Peaks and one on O'Sullivan. One larger one appeared to be a Storm Slab on the New Snow/Old Snow interface (SS-N-R1-D2-I). The two others were D1/R1 wind slabs on N aspects in areas that are clearly loaded by S/SW winds. One of these is a repeater where the old crown was present and was 18" deep at the deepest point. All these appeared to run during or at the end of the storm cycle.
