Avalanche problems

  • Wind Slabs

    • Treeline
    • Below treeline
    Likelihood
    Possible
    Size
    1–2
    Last week's snow was distributed by mostly moderate to strong winds into windslabs and cornices on North through Southeast aspects. Recent avalanches have started from rock bluffs or cornice failures and have triggered deeper weak layers.

  • Persistent Slabs

    • Treeline
    • Below treeline

    The buried surface hoar layer remains a concern in areas that have not recently avalanched. Solar effect will weaken the bridging strength of the slab on exposed slopes.

  • Loose Wet

    • Alpine
    • Treeline
    • Below treeline
    Likelihood
    Possible - Likely
    Size

    Surface snow is responding to the strong solar radiation effect that happens in March and April. Ice climbers should also be wary of large pillows of snow still overhanging routes on solar aspects.
