Previous strong winds have stripped exposed alpine and tree-line terrain, creating wind slabs in cross-loaded and lee features.
You must keep this basal layer on your radar as triggering is possible in some features, like approaching or moving between pitches on ice climbs. Be cautious in steep terrain if you find yourself standing on the surface and not wallowing in facets, that's the problem slab.
No new avalanche activity was observed on the Icefields parkway.
Strong winds have stripped exposed terrain in the alpine and at tree-line. Continued wind slab development in leeward terrain. The snowpack is 45-80cm deep and is weak and facetted throughout. Basal weaknesses are a combo of large facets and chains of depth hoar.
