Lo esencial

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–3
    Field tests in the Vermillion region were producing moderate planar compression results down 25-35cm at treeline and above. These wind slabs could be triggered in steep, wind effected areas by a skier or climber.

    A well settled midpack overrides a weaker facetted base. This weak base is found most places except the west side of the divide. Beware of steep shallow snowpack areas (where the likelihood of triggering this basal layer is highest).
