Regions

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

Watch for wind slabs from recent strong southwest winds and new snowfall, and remain especially cautious of the deep persistent weak layer in thin, rocky areas.

For the best skiing and riding, look to sheltered areas.

Avalanche Summary

Natural deep persistent avalanches have been occurring periodically in shallow rocky areas. The last ones observed were:

Jan 2- A natural 2.5 deep persistent avalanche was observed at Parkers Ridge, likely triggered by cornice fall.

Jan 4- A natural 2.5 deep persistent avalanche was observed on Mt. Morden Long.

Snowpack Summary

Winds have redistributed snow into windslabs in alpine and open treeline areas. The midpack is supportive and sits above 40-60 cm of faceted snow that makes up the lower snowpack. Basal facets and an early season melt freeze crust are located ~30cm off of the ground and remain active as a weak layer in the snowpack.

Average snow depth in the Icefields Parkway area is 140-200cm and in the Maligne area average depth is 100cm.

Terrain and Travel Advice

Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
Be mindful that deep instabilities are still present and have produced recent large avalanches.
Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

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.
