Regions: Jasper.

Snowpack Summary
Last weeks storm snow is providing support underfoot. Snow conditions at treeline is variable from powder in sheltered areas, to slabs and sastrugi in exposed locations and near ridge crests. The Dec. 11th persistent weak layer is buried 50-100cm. The deep persistent weakness lingers near the ground in the depth hoar and facets.
Avalanche Summary
No new avalanches were noted on Wednesday's patrol. Last weeks storm initiated several deep releases from the alpine up to size 3. They appear to have been triggered by cornice failures from South Easterly facing slopes. It is likely these occurred at the interface of last weeks snow and then stepped down to the basal weakness.
Confidence
Intensity of incoming weather systems is uncertain on Saturday
