    Size

    Strong westerly winds have created a 10-30cm soft slab. A skier near the Icefields triggered a size 1.5 at treeline and a size 2 natural was observed from the alpine near Maligne Lake.

  • Deep Persistent Slabs

    Increase 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.
