Points saillants

Up to 40cm of new snow fell over the weekend, which has improved the ski quality. Look out for new wind slabs above treeline. Dry loose avalanches may still occur in steep terrain until the recent snow has a chance to settle.

    Sunday's field patrol noted that moderate ridgeline and alpine Southwest winds were transporting the new storm snow into potential windslabs. Despite the lack of natural activity one should remain highly suspicious.

    The weekend brought 30-40cm of new snow to the Icefields. As a result, loose dry avalanche activity was noted in the Icefields area. This condition will persist as the storm snow settles.

Avalanche Summary

Sunday's Icefield team noted numerous loose dry avalanches up to size 1.5. Some were triggered in that afternoon as the sun came out. There was one slab avalanche observed. A size two in the fan of a couloir on Snowdome.

Snowpack Summary

The Icefields received up to 40cm of new snow this weekend. Moderate southwesterly winds have created new windslabs above treeline. The mid pack generally consists of firm windpressed snow from earlier wind events. Snow amounts in the alpine vary greatly, with some areas blown free of snow, while other areas are filled in. The weather station near the Parkers parking area has a snow depth of 110cm.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
