Avalanche Summary

No new avalanches observed

Snowpack Summary

5-10 cm of snow fell over the weekend and is now very wind affected. It overlies stiff old windslabs and sastrugi in the alpine and at treeline. Melt freeze crusts have formed below treeline and in steep solar locations at higher elevations. Where they exist, ski quality is poor as they are unsupportive and breakable. The lower snowpack is well settled with no significant weak layers.

Snowpack depths at treeline range from 80 - 120 cm.
