Regions

East Kakwa, Tumbler.

Soft snow and fun riding can still be found in sheltered areas.

Remain cautious in shallow rocky start zones.

Confidence

Moderate

Avalanche Summary

No new avalanche activity has been reported in the past few days, but reports have been limited in this region.

Keep posting your observations to the Mountain Information Network!

Snowpack Summary

Surface snow is predominantly wind-affected, with sastrugi in many open upper elevation areas.

Limited soft snow may be found on the surface in more sheltered areas above 1500 m.

The mid-pack is generally made of weak, sugary faceted crystals, along with a crust near the base of the snowpack.

Total snowpack depths in this region are generally shallow, with an average of around a meter at treeline.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.

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.
