Regions

Northwest Inland, Kispiox, Microwave-Sinclair, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

Low avalanche hazard means it may be possible to attempt bigger or more extreme lines. Check for pockets of wind slab before committing to high-consequence slopes.

Avalanche Summary

On Friday, a small ( size 1) skier-triggered size wind slab avalanche was reported in the Hudson Bay Mountain area. This avalanche failed on a facet layer that exists above a crust, about 20 cm deep.

Check out this excellent MIN post for full details.

Snowpack Summary

A variety of conditions can be found in exposed terrain at treeline and above, including crusty and wind affected surfaces. In isolated areas in the alpine, hard wind slabs overlie weak sugary facets above a hard crust and may be susceptible to human triggering. In sheltered terrain, there is up to 5 cm of snow on top of a breakable crust and new surface hoar development. The remainder of the snowpack is generally not concerning.

Check out this MIN from our field team in the Babines.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.

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.
