Points saillants

Travel conditions are excellent and good skiing can be found on sheltered North aspects.  While we have moved to Low hazard at all elevations...remember that it may still be possible to trigger an avalanche in isolated locations! CJ

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–2
    The recent snow has created thin wind slabs in the alpine and at treeline which could be a problem in steep confined terrain such as gullys and couloirs.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    1–3
    A lack of avalanche activity and hard test results show that triggering the weakness at the base of the snowpack is unlikely, however the variability in snowpack depth means it is worth watching for thin areas where triggering may still be possible. 

Weather Forecast

Light North winds, a mix of sun cloud with no significant precipitation, and continued cold temperatures of -25'C with highs of -15'C are forecast for the next few days.  Dress warm!

Snowpack Summary

5-10 cm of recent snow sits on the January 30th surface hoar below treeline. In the alpine this recent snow is over a firm wind slab or a thick sun crust on S & W aspects. The snowpack has gained strength over the past few weeks, and snowpack tests are now producing hard results 20 cm above the ground in the facetted base layer.

Avalanche Summary

No new avalanches have been observed or reported.
