Snowpack Summary
The steep South facing aspects are getting moist with warm temperatures and sun effect weakening the surface layer during the afternoons. As an overview, the snowpack is generally well-settled.? Near the base of the snowpack, the crust/facet layer appears to be inactive but still produces the sudden planar and collapse shears in isolated areas, especially in the Northern part of the region. Although unlikely, triggering an avalanche on a basal may be possible from thin snowpack areas or with a very heavy trigger.
