Avalanche Summary

Natural windslabs to size 1.5 observed in the alpine and upper treeline and natural wet loose on solar slopes to size 1 observed this week.

Snowpack Summary

Alpine - Recent SW winds have formed thin stubborn windslabs in lee features. Fetches are scoured to rocks and old crusts. Feb 03 crust/facets may still exist at high elevations and are down 100-120 cms

Tree Line - Wind affected snow at this elevation has been settling with warm temps. This overlies a well-settled lower snowpack.

Below Treeline - Moist faceted snow to ground with a new surface crust forming overnight. Most solar aspects are now below threshold for avalanches
