Regions

Dogtooth, East Purcell.

Heightened avalanche conditions exist in specific terrain features where deeper pockets of snow sit over weak layers in the upper snowpack.

Confidence

Moderate

  • We are uncertain due to a highly variable snowpack.

Avalanche Summary

On Saturday a skier-triggered size 2 wind slab was reported in the Dogtooth range, with limited information as to elevation, aspect, etc. There have also been several reports of cornice falls in recent days, natural and explosive-triggered, size 2.

If you are heading into the backcountry, please share your observations with the Mountain Information Network.

Snowpack Summary

5 to 15 cm of new snow blankets a variable upper snowpack with a number of weak interfaces.

Depending on aspect and elevation, the top 30 cm may contain one or two layers of crust, facet and/or surface hoar formed in late January and early February. These layers are expected to become increasingly problematic as they get buried deeper.

The mid and lower snowpack is generally well settled, with no significant concerns.

Weather Summary

Monday
Mix of sun and clouds. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Tuesday
Mix of sun and clouds. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -8 °C.

Wednesday
Mostly sunny. 1 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -8 °C.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Closely monitor how the new snow is bonding to the crust.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
