Avalanche Problems

Wind Slabs

Variable winds have created a complex situation of cross and, reverse loaded features through the region. Stripped ribs, ridge-tops, and open features threaten to push users into areas where the snow is over-loaded and created layered wind-slabs.

Caution in lee and cross-loaded terrain near ridge crests.Be careful with wind loaded pockets. Be aware of wide variation in snowpack depth

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

The faceted snowpack has little cohesion producing loose dry avalanches in steep terrain. This is concerning for ice-climbers and skiers in confined/exposed terrain.

Be very cautious with gully features.Use caution above cliffs where small avalanches may have severe consequences.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
