Regions

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

Light snowfall and wind blowing from the west will make wind slabs the main concern.

Confidence

Moderate

Avalanche Summary

Several natural wind slab avalanches to size 2 were reported Sunday and Monday in the alpine and tree line in the Pine Pass area and in the MacGregors. There was a size 1 human triggered wind slab avalanche reported on Sunday in the Pine Pass area.

Data is very limited in this region. Please submit your MIN (Mountain Information Network)

Snowpack Summary

15 to 30 cm fresh snow accumulated over the weekend. At upper elevations, wind has redistributed snow to lee features.

The recent snow overlies a hard melt-freeze crust. There are no deeper layers of concern.

Data is very limited in this region.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.
