Signs of instability at Crater Lake

Mild temperatures observed while skinning to Crater Lake, with moderate winds and evidence of previous wind transport. Current blowing snow observed on surrounding slopes once we reached Crater Lake, with light snow beginning around 10am. Mitt pits and ski cuts indicated instability both within the wind loaded snow and on the facets below the recent storm snow. Two ECTs on N aspects at 8800ft propagated on the Dec 1st facets. One previous avalanche was observed adjacent to our second ECT location. Debris was buried by additional storm snow (not just today's minimal new snow at the time of observation), and the crown was not visible. Other avalanche paths in the area were not easy to see due to blowing snow and current snowfall. Upon descending back to Hope Valley, the snow surface had become wet and sticky from warm temps and mixed rain and snowfall.
