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.

Snowpack Summary

3-4 cm of fresh snow found in the Icefields Parkway.

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.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
