Regions

Jasper, Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Maligne, Marmot, Miette Lake, Pyramid.

Keep in mind the weak, facet layer at the bottom of the snowpack, which is more likely to be triggered in areas where the snowpack is thinner and the terrain is steeper.

Decent turns can still be found in wind protected areas.

Confidence

Avalanche Summary

On January 20th, a skier triggered a size 2.5 outside the Lake Louise ski area. It was triggered in a cross loaded, shallow feature and ran on a basal layer.

On Jan 17th, Marmot Basin Ski Patrol remote triggered a size 3.5 outside of the ski area that ran on a basal layer.

Snowpack Summary

Surface hoar and/or surface faceting continue to grow and can be found up to 2700m and likely higher. Otherwise, surfaces are firm and wind impacted. Soft snow remains in sheltered areas. Solar slopes host variable old crusts, especially on steeper aspects. The snowpack is generally deeper in the Icefields and shallower at Maligne lake.

Terrain and Travel Advice

  • Avoid areas with a thin or variable snowpack.
  • Make observations and continually assess conditions as you travel.
  • Be mindful that deep instabilities are still present in the snowpack.

Problems

Deep Persistent Slabs

Deep Persistent Slab avalanches are the release of a thick cohesive layer of hard snow (a slab), when the bond breaks between the slab and an underlying persistent weak layer deep in the snowpack. The most common persistent weak layers involved in deep, persistent slabs are depth hoar or facets surrounding a deeply buried crust. Deep Persistent Slabs are typically hard to trigger, are very destructive and dangerous due to the large mass of snow involved, and can persist for months once developed. They are often triggered from areas where the snow is shallow and weak, and are particularly difficult to forecast for and manage.
