Points saillants

The danger is at moderate currently, but forecasters are still approaching Alpine and treeline terrain as if its at considerable.  We are unwilling to commit to bigger terrain. 

Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    If this layers if triggered, there is a likelihood of entraining the entire snowpack with it

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–3
    The big concern is that if anything gets triggered within the snowpack, then the entire snowpack would fail on the basal facets.

Snowpack Summary

Below treeline travel is fairly grim.  Expect ski penetrations to ground in many areas and the best solution to getting up to the skiing is via an old established up-track.  At treeline and above the upper snowpack has 30-40cm of settled snow that is overlying the weak basal facets.  Moderate compression tests that are sudden collapse in nature are being observed at this interface.  Thin weak spots are the most likely areas where a skier could cause a failure.  As a result choose supported terrain, and avoid thin areas.  The only skiing to be found is at treeline and above.  If you are looking for turns below treeline, look elsewhere!
