    This problem was most active in the Maligne and surrounding Jasper area where the average snow pack is shallow but is proving much less active in the Icefields area.

Weather Forecast

Cool temps, freezing level dropping and gusting SW-ly ridge top winds. Precip forecasted overnight (4-6cm in Icefields; trace amounts in Maligne) but to be perfectly honest, I'll believe it when I see it.

Snowpack Summary

Maligne/Jasper: Variable snow depth above tree-line, relative to exposure. Average HS 70cm. Surface wind slabs and persistent slab down 40-90cm. Icefields: Variable snow depth above tree-line, relative to exposure. Average HS 120cm. Widespread wind slabs overlaying supportive mid pack and weak base.

Avalanche Summary

Previously noted size 2 slab avalanches on cross-loaded Alpine features, west aspect. Significant whining and moaning from travel partners once you step off the beaten track BTL in the Maligne valley, as well as whumphing and cracking.
