Highlights

Although avalanche conditions are slowly improving, caution is still advised in larger Alpine features. Numerous early season hazards remain a concern, but travel conditions have improved.

Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–3
    Both hard and soft wind slabs are found in lee and cross-loaded features in the Alpine and at Treeline. Steep and unsupported features are the primary concern, and gully features should be evaluated carefully.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–4
    Avalanches that are initiated in the upper snowpack could step down to the October crust or the ground.
