Regions

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

Conservative terrain choices are the best defense against uncertainty in persistent slabs.

Despite the recent wind, good riding can still be found in sheltered features.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

Over the weekend a few dry loose avalanches were observed in steep terrain. A skier accidentally triggered a cornice while trying to create access to a ski line, this resulted in a dry loose avalanche on the slope below.

Field observations have been limited over the last few days. If you are heading to the backcountry, please submit your observations to the Mountain Information Network.

Snowpack Summary

Previous strong wind has created pressed surfaces and wind slab in exposed terrain. A new sun crust could be on or near the surface.

20 to 40 cm of soft snow from last week remains in wind-sheltered areas. Reports suggest this snow is bonding fairly well to previous surfaces.

A thick crust with facets over it, from late January, can be found down 100 to 200 cm. We do not have concerns about the snowpack below this layer.

Wednesday
Mostly cloudy. 2 to 10 cm of snow. 30 km/h east ridgetop wind. Treeline temperature -5 °C.

Thursday
Mostly cloudy. 1 to 2 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • In times of uncertainty, conservative terrain choices are our best defense.
  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.

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.
