Snowpack Summary

Supportive melt-freeze crust on all aspects and elevations; northerly aspects above treeline may still hold dry snow. The mid-pack is thick and supportive. Persistent weakness near the bottom of the snowpack will remain a concern in shallow areas and northerly alpine aspects.

Freezing levels continue to rise this week - expect increasing avalanche activity in the afternoon.
