Points saillants

Wind slabs are a concern in isolated alpine lee features.

Ski quality has been affected by the recent winds but good riding can still be found on sheltered tree line and below tree line slopes.

Early season hazards are also still a significant concern out there, coverage is very thin in many areas.

    Moderate westerly winds have redistributed snow in the alpine, and formed wind slabs in isolated leeward features.

Avalanche Summary

No new avalanches have been observed or reported in the past few days.

Confidence

Moderate

Snowpack Summary

About 3–4 cm of fresh snow was found along the Icefields Parkway.
In sheltered areas, roughly 30 cm of soft snow overlies a supportive snowpack all the way to the ground. We’re currently tracking a mid-November melt-freeze crust located in the mid-pack, though it has not shown any activity in our profiles.
Alpine and exposed treeline slopes are beginning to show signs of wind effect, which is mostly just impacting riding quality at this point.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
