Points saillants

Tests show that it is still possible to trigger windslabs. These could be buried under a layer of snow of lower density, making them more difficult to identify.

    The tests demonstrated a likely initiation and propagation of windslabs. Reactive windslabs can be expected in departure zones, at convexities and in cross-loading zones. Windslabs rest on facets, making them more sensitive to triggering.

Avalanche Summary

No new avalanche was reported or observed.

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

Snowpack Summary

There are recent windslabs on southeastern to western slopes. The height of the snowpack is extremely variable in the alpine and at treeline, depending on elevation and aspect.

In sheltered areas, 15 to 25 cm of lower-density snow cover a consolidated snow interface that lay on top of the December 30 combo of facets and crust. Facets and depth hoar are developing at the base of the snowpack.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Be cautious of buried obstacles especially below treeline.
