Wind slabs in the alpine seem to be well-formed and reactive. Remain vigilant, as the cold can quickly turn a small incident into a critical situation.

Avalanche Summary

We observed the deposition of an avalanche at the foot of the Couloir à Benny. The size 2 avalanche was about 24 to 48 hours old and we assume it was caused by a natural trigger. We weren't able to see the crown, perhaps it was filled in by yesterday's strong winds.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

In the alpine and at treeline, we find a variety of surfaces, ranging from surface obstacles, hardened snow to recent wind slabs on northeast to south-facing aspects. In areas protected from the wind and below treeline, there is between 10 and 30 cm of powdery snow. The middle of the snowpack appears to be fairly stable (snowpack consolidation), although facets are developing near the crusts at the base of the snowpack. Snow depth at mid-mountain varies between 90 and 130 cm.

  • The best and safest riding will be on slopes that have soft snow without any slab properties.

Problems

Wind Slabs

An icon showing Wind Slabs

There are new wind slabs on the northeast to south aspects. They are reactive to human triggering. There may still be some stubborn, isolated wind slabs formed on January 28 on North to East aspects. We have few recent observations in the Alpin.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.
