Regions

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

Low avalanche Danger doesn't mean no avalanche danger.

During a flight through the region on Tuesday we confirmed that the snowpack levels are below average. Deepest snow is along the divide. Avoid exposure to steep solar aspects.

Confidence

High

Avalanche Summary

No avalanches reported or observed on a flight through the region on Tuesday.

Snowpack Summary

Some recent northerly winds have created small isolated windslabs that do not extend far downslope along ridgelines that are overlying a thin melt freeze crust. The snowpack is mainly facetted but generally well settled. Widespread hard windslabs can be found in most open areas at treeline and above. These slabs are stubborn to trigger but if you are in steep thin terrain, you may be able to find a pocket that is reactive.

The Kananaskis valley is generally below threshold in many areas at treeline and below.

Weather Summary

See Table. Snow and cold coming for the weekend.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.

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.
