Avalanche Summary

No new avalanches were reported on Monday. One small slab avalanche (size 1) was triggered remotely by a group of skiers on Sunday. It was 40 cm thick and occurred on an east aspect at 1400 m.

Snowpack Summary

Five days of strong outflow winds have scoured the surface in exposed terrain and formed hard wind slabs on all aspects. South facing slopes likely have crusts on the surface. Roughly 30-50 cm of snow sits above a layer of cold, soft faceted snow and surface hoar. This layer has been reactive in some snowpack tests and could enhance the propagation of wind slabs if triggered. The lower snowpack is generally considered strong.
