Regions

Waterton Lakes, Waterton.

Low hazard usually means you can start exploring some more complex terrain. Be aware that the temps are some of the coldest we have experienced this winter and the days are still short. Try plan your day to be back at the car before dark.

Confidence

Moderate

Avalanche Summary

No new avalanches observed

Snowpack Summary

A few cm's of new low density snow overlies stiff old windslabs and sastrugi in the alpine and at treeline. Melt freeze crusts have formed below treeline and in steep solar locations at higher elevations. The lower snowpack is well settled with no significant weak layers.

Snowpack depths at treeline range from 80 - 120 cm.

Weather Summary

Sun

Light cloud and flurries. Alpine high of -15°C with moderate north winds.

Mon

Clear with no precip expected. Moderate north winds and a high of -16°C in the alpine.

Tues

Some cloud in the afternoon, no precip expected. Winds moderate to strong out of the NW. Alpine high of -8°C.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.

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.
