Lo esencial

Travel continues to be good on a mostly supportive snowpack. With cold temperatures in the forecast enjoy it while it lasts!

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1.5–2.5

    Watch for crossloaded and reverse loaded slopes from northerly winds. Watch for hollow sounds and cracking. Consider testing smaller slopes before committing to larger features; windslabs could initiate deep layers.

  • Deep Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    2–3.5

    Triggering this layer would be a high consequence event - cautious decisions and thorough investigation is necessary. More likely to trigger this layer in transitions from thin snowpack to deeper loaded pockets or terrain features.

Snowpack Summary

Watch out for crossloaded or reverse loaded slopes from northerly winds. Mid snowpack has settled well with a 2cm rain crust present below the recent snow up to 1950m. Another crust near the base of the snowpack continues to promote basal faceting adding to our deep persistent slab concerns

Avalanche Summary

No new activity observed on the Icefields Parkway. Marmot Ski Resort continues to get explosive triggered avalanches to slide on the deep persistent layer
