    A layer of weak facets is lurking at the bottom of the snowpack. Though there has been limited activity on this layer, it is still on our mind with consistent sudden collapse results in test profiles.

Snowpack Summary

20-30cm of facetting storm snow has been redistributed by SW winds. This new snow sits on a variety of previous wind affected surfaces including a melt freeze crust up to 2000m on all asp. The Midpack is strong in deep snowpack areas but the facets at the base of the snowpack remain a concern in shallow areas.
