Points saillants

Windslabs and variable snow depths will be found at and above treeline. Trail breaking on skis is generally easy at all elevations.

Problèmes avalancheux

  • Wind Slabs

    A return to seasonal temperatures and light winds should allow windslabs to begin to bond with the older snow surface. Skier triggering is still possible on lenses of windslab.

  • Deep Persistent Slabs

    Taille

    Large avalanches could occur where smaller avalanches or cornice failures trigger a collapse in deep basal facets. A strong midpack is bridging this layer, except near wind exposed terrain.
