Avalanche problems

  • Wind Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Unlikely - Possible
    Size
    1–3
    Slabs are present on exposed slopes and steep gully sidewalls. A significant wind slab release was noted Friday off Mt Kitcheners ridge facing the Icefields center. It was 50cm deep, 38 degrees or less in places, and ran a fair distance.

  • Loose Wet

    • Alpine
    • Treeline

    Expect a higher probability of naturally occurring moist avalanches in and around steep gullies, and rocks, during the heat of the day. These loose snow avalanches have the potential to trigger windslabs and deep slabs.

  • Deep Persistent Slabs

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    2–4
    These deeper layers can wake up unexpectedly. Natural avalanches continue to fail on deep layers. Profile Saturday found Feb14 surface hoar buried 80cm, unreactive yet present.
