Regions

Waterton Lakes, Waterton.

The wind continues to blow down here in Waterton and forming windslabs in the alpine and at treeline. Decent skiing continues to exist on sheltered, low-angle slopes where a new temperature/solar crust does not exist.

Confidence

Moderate

Avalanche Summary

No new avalanches observed

Snowpack Summary

5-10 cm of snow fell over the weekend and is now very wind affected. It 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. Where they exist, ski quality is poor as they are unsupportive and breakable. The lower snowpack is well settled with no significant weak layers.

Snowpack depths at treeline range from 80 - 120 cm.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.

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.
