Avalanche Forecast
Regions: Brazeau, Churchill, Cirrus-Wilson, Fryatt, Icefields, Jasper, Maligne, Marmot, Miette Lake, Pyramid.
Avoid steep terrain where a stiffer slab overlies a weak facetted base (wind loaded features are prime suspects).
Triggering a Deep Persistent Slab avalanche remains our main concern.
Confidence
Moderate
Avalanche Summary
No new avalanches have been observed or reported in the last few days.
Snowpack Summary
Up to 10cm of new snow has fallen with generally very light winds.
The snowpack is mostly made up of facets and ranges in depth from 60 to 120 cm at treeline and above. At the bottom of the snowpack there are multiple early season crusts with facets above and below.

Terrain and Travel Advice
- Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
- Be especially cautious as you transition into wind-affected terrain.
Avalanche Problems
Deep Persistent Slabs
A variety of crusts with facets above and below exist at the bottom of the snowpack. These layers are going to be with us for a long time and pose a low probability, high consequence situation if triggered.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2.5
