Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    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

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely
    Dimensione

    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.
