Avalanche Summary
There was wide spread avalanche activity on Thursday with numerous natural, explosive controlled, and skier accidental avalanches ranging from size 1-2. These avalanches failed on the layer of surface hoar down 30 to 40cm on all aspects at treeline and in the alpine.
Snowpack Summary
Between 20 and 50 cm of new snow continues to settle into a soft slab sitting above a widespread layer of surface hoar, facets, and/or sun crust on steep south aspects. 10-20 cm below this is a second buried weak layer of surface hoar and/or a crust. The mid and lower snowpack is generally strong, with the exception of shallower snowpack areas that may be more faceted. At lower treeline elevations recent rains have saturated the upper snowpack. At higher elevations moderate southerly winds have formed loaded lee features at treeline and in the alpine.
