Regions

Waterton Lakes, Waterton.

There is good skiing to be had in sheltered areas at treeline. Wind slabs may still be reactive to skier triggering in exposed areas - watch for areas of stiff, wind affected snow and avoid steep lee features.

Confidence

Moderate

Avalanche Summary

No new natural avalanches have been observed in the park, however observations have been limited.

The local ski area has reported wind slab results up to size 2 with explosive control on Sunday and Monday.

Snowpack Summary

Up to 30 cm of new snow on the weekend with strong winds formed windslabs in lee features in the alpine and treeline. Unconsolidated snow exists in sheltered areas. Snow depths at treeline range from 80-120 cm. There is a basal crust 10-20cm off the ground.

Below treeline, up to 10 cm of new snow sits on a firm crust.

Weather Summary

Tues

Mix of sun and cloud, light to moderate NW winds. Alpine high of -8°C.

Wed

Cloudy with sunny periods, light westerly winds. Alpine high of -5°C.

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.
