Dogtooth, East Purcell.

7 am update: Heightened avalanche conditions exist in specific terrain features where deeper pockets of dry snow sit over a weak layer.

Confidence

Avalanche Summary

On Thursday and Friday, avalanche activity consisted of several natural and skier-triggered loose wet avalanches, size 1-2, and a few natural and explosive-triggered cornices, 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 mostly crusty surfaces. The old surface may remain dry snow in the high alpine and moist at low elevations.

A weak layer formed in late January sits 5 to 15 cm below the surface. The layer consists of surface hoar over a crust and/or facets. This layer is expected to become increasingly problematic as it gets buried deeper.

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

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

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.

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.
