Regions

Kananaskis.

Most open areas have wind effect at all elevations. With the sunny skies, this is a good time to look at tours that have more travelling than skiing.

Snowpack Summary

The windslabs are still there and widespread. Not much change until we get some more snow. Approach cross loaded features and lee loaded zones along ridges with extra care.

Terrain and Travel

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Pay attention to isolated alpine features as well as cross-loaded features at treeline.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
