    Size

    Soft slabs 10-50cm overlay a buried surface hoar layer. This layer will produce a natural avalanche cycle with more snow load. Avalanche control on 93 produced several size 2 soft slabs that started in the middle of the slope at treeline.

  • Deep Persistent Slabs

    • Alpine

    Increased loads with wind or new snow may awaken this instability. Size 2 surface slab avalanches may step down to this layer producing much larger avalanches.
