Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

Sheltered areas at treeline and below still offer some good skiing. Widespread wind slabs in the alpine.

Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Widespread wind slabs in the alpine from 10-40cm. On North aspects in Burstall Pass, a hard 10cm thick wind slab was present and sounded hollow. The January 30 interface(crust/facets/surface hoar) is present about 20-40cm down but mostly producing hard test results which were non-planar. The midpack is supportive in most places, but in rocky areas it has become very weak and "punchy" while walking/sking.

Terrain and Travel Advice

Carefully evaluate big and steep terrain features before committing to them.
Be careful as you transition into wind-affected terrain.
Avoid steep terrain that is rocky and thin.

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.
