Avalanche Summary
Several size 1-2 natural windslab avalanches were observed in treeline lees over the last four days.
Snowpack Summary
Extreme winds have stripped most alpine features and redistributed snow deep into lees. Firm windslabs are most prevalent at treeline. The January melt freeze crust is now buried 50-100cm. Alpine and Treeline midpack is well settled and overlies basal facets and depth hoar. Below treeline, the Jan Crust overlies facets and depth hoar to ground.
