Avalanche Summary
Recent observations have been limited to small pockets of old wind slab lingering on easterly aspects. Crowns and debris remain visible from last week's wind slab avalanche cycle up to size 2.
Snowpack Summary
5-10 cm of new snow arrived overnight with strong northerly winds. The fresh snow sits over crusts and wind-hardened surfaces.
The mid snowpack is composed of mainly dense, wind affected snow with a few crust layers. The lower snowpack is dense and well bonded from warm temperatures, rainfall and subsequent refreezing.
