Snowpack Summary
Up to 20 cm of recent snowfall exists in sheltered areas. Strong to extreme wind has formed firm, wind-affected surfaces at the treeline and above. Wind slabs may have formed in lee and cross-loaded terrain.
The upper snowpack contains a melt-freeze crust and facets layer, particularly in south-facing terrain. Recent scouring wind may have exposed the crust in some 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.
