Regions

Dogtooth, East Purcell.

Watch for unstable slabs on isolated terrain features where pockets of deeper snow sit over a weak layer.

Confidence

Avalanche Summary

On Wednesday, avalanche activity consisted of several loose wet avalanches, size 1-2, and a few cornice failures, size 2.

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

Snowpack Summary

A dusting of new snow falls over a thin surface crust or moist snow.

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. In most areas it is still too shallow, but will likely become a concern as it gets buried deeper.

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

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
