Avalanche Summary
Loose wet sluffs up to size 2.0 have been reported on south and west aspects. Isolated large cornice falls have also been reported; none of these recent cornice events have pulled slabs on the slopes below.
Snowpack Summary
Recent warm temperatures have created melt freeze crusts up to 2200m on all aspects and to ridgecrest on south and west facing terrain. These crusts break down with daytime warming and the surface snow can lose cohesion as a result. Isothermal conditions as deep as 100cm at treeline on south aspects have been reported. Cornices are huge!Mid and lower snowpack layers are well bonded.
