Regions

North Rockies, East Kakwa, Tumbler.

Recent strong winds have formed fresh wind slabs which will likely remain reactive to riders. Watch for wind slabs on leeward terrain features at upper elevations.

Confidence

Avalanche Summary

On Thursday and Friday, observers reported evidence of wind slab activity, suspected to have run mid-week, size 1-2 on north through east-facing aspects.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

Recent snow and strong winds have buried a crust formed in mid-February up to 90 cm deep. This crust is expected to be most widespread and thickest at treeline and below, becoming thinner or absent at higher elevations. Weak, faceted snow may exist above the crust, or in place of the crust at higher elevations.

The remainder of the snowpack is generally well consolidated, with no widespread layers of concern. The main exception is shallow, rocky terrain, where the snowpack is inherently weaker and early-season basal weak layers may still persist.

Check out these recent MIN posts from our field team on Thursday and a local pro on Friday.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.

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.
