Avalanche Summary

On Thursday several natural wind slab avalanches up to size 2 were observed in the region as well as natural wind slab avalanches up to size 3 in the neighboring Waterton region.

Snowpack Summary

New wind slab can be found on easterly aspects in exposed treeline and above. 10 to 20cm overlies a crust on solar aspects and all aspects below 2000m. Moist snow will likely be observed below treeline.

Terrain and Travel

  • Expect slab conditions to change drastically as you move into wind exposed terrain.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.
