Regions

East Kakwa, Pine Pass, Tumbler.

Watch for isolated wind slabs at upper elevations. Conditions remain rugged, with firm surfaces and a shallow snowpack, so choose objectives suited to early-season hazards.

Confidence

Low

Avalanche Summary

No recent avalanches have been reported, but we suspect rider-triggered wind slabs may be possible in the alpine and at treeline on wind-loaded slopes.

Please consider posting a MIN if you are heading out in the backcountry!

Snowpack Summary

The surface snow in the alpine and at treeline is variable with soft snow in sheltered areas and firm wind-affected snow. A supportive melt-freeze crust is down 15 cm up to 1300 m and disappears around 1500 m and higher.

The average snow depths at treeline elevation are anywhere from 40 to 60 cm.

Below treeline the snowpack tapers significantly, and a rain crust may be found.

Watch out for variable snow conditions and quality. Early-season hazards such as open creek, rocks and stumps.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Shooting cracks, whumpfs, and recent avalanches are strong indicators of an unstable snowpack.
  • Be cautious of buried obstacles, especially below 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.
