More detailed information about the snowpack: 

ECT scores at this location on Dec 12 were ECTP and have now changed to ECTN. Continued faceting has weakened the overlying slab. East wind event Dec 15 caused significant additional scouring in this area. Soft faceted snow that existed on the snow surface is now gone in near treeline areas.
