Snowpack Summary
55cm of storm snow and strong S winds have formed reactive storm slabs at treeline & above. On solar aspects this slab buries a suncrust that was showing sudden planer results in snowpack tests before the storm. The storm snow will need time to settle & bond to old snow surfaces. Underneath, the mid & lwr snowpack are unusually weak and facetted
