Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Likely
    Size
    2–3
    Recent strong s.w. winds have created windslabs up to a metre thick on lee slopes in the alpine (primarily N- E aspects). These slabs override the January 20 facets and are reactive to skier triggering.

  • Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline

    In many areas east of the divide where the snow is shallower the midpack overrides a layer of weak basal facets. Be extra cautious of thin snowpack areas where the chance of triggering this layer is highest.
