The eastern and southern slopes appear to be well loaded with snow, but the risk of triggering wind slabs remains uncertain.

Snowpack Summary
At treeline and in the alpine, surface snow is strongly affected by wind, resulting in great variability in its distribution and density. There is considerably more snow in the northern part of the forecast area (Mines versus Lyall).
The average snow depth at treeline varies between 90 and 120 cm. Within this snowpack, we find a few weak layers:
A thin layer of frost at a depth of around 20 cm.
A layer of facetted grains approximately 40 cm deep.
Melt-freeze crusts at 60 cm and 80 cm.

Terrain and Travel Advice
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
- Watch for areas of hard wind slab on alpine features.
Problems
Wind Slabs
The formation of new wind slabs seems to have eased, but low temperatures are delaying the stabilization of the snowpack. Hard wind slabs are more difficult to trigger, but they will propagate if triggered. They rest on fragile layers that proved reactive in our tests.
