Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–3
    Isolated wind slabs in the high alpine are still triggerable in steep terrain. Thinner snowpack areas in steep, gully sidewalls and unsupported slopes will be most vulnerable.

  • Cornices

    • Alpine
    • Treeline
    • Below treeline
    Likelihood

    Size
