Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

Investigate for wind slabs around ridges and lee features, especially as you move into more open or alpine terrain.

Confidence

Moderate

Avalanche Summary

We've had no recent avalanche reports and very few recent field reports.

Please consider submitting a Mountain Information Network report if you head out. Even a photo of the mountains or an idea on the surface conditions helps!

Snowpack Summary

15 to 30 cm of fresh and recent snow overlies a hard melt-freeze crust. Wind has impacted surface snow in open slopes at treeline and higher.

The lower snowpack is well bonded with no concerns currently.

Data is very limited in this region.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs 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.
