Up to 10 cm of recent snowfall exists in sheltered areas. Strong to extreme wind has formed firm, wind-affected surfaces at the treeline and above. Hard wind slabs have formed in lee and cross-loaded terrain.
A melt-freeze crust and facets exist in the upper snowpack, particularly in south-facing terrain. Winds likely have scoured recent snow, leaving the crust exposed on the surface in exposed areas.
Snowpack depth varies significantly across the region. Windward slopes may have as little as 50 cm of snow, while leeward slopes could have up to 200 cm
