Avalanche Summary

Numerous solar induced point releases to size 1.5 were reported running on steep, south-facing terrain. These occurred in response to warming on Saturday. A few size 1 slabs have also been reported running on the January 23rd interface. They ran 30cm deep between 1800m and 1900m on east facing terrain.

Snowpack Summary

The snow surface is a combination of hard and soft wind slabs in exposed areas, settled storm snow in more sheltered terrain, and a crust or moist snow on solar aspects. About 30-40cm below the surface, an interface of surface hoar, facets or sun crust buried on Jan 23 continues to be a concern among professionals in the region. The snowpack below this is generally well bonded.
