Regions

Glacier.

Be on the lookout for isolated pockets of wind slab in the alpine.

The shallow snowpack remains the primary travel hazard with lots of rocks and trees at lower elevations. Allow adequate time for egress and emergencies during these short days.

Confidence

High

Avalanche Summary

There has not been any recent natural or human triggered avalanche activity reported in the last few days.

Thanks for the MIN reports!

Snowpack Summary

The surface consists of a thin suncrust on steep solar aspects or minor wind effect in exposed alpine areas. Good powder can still be found in protected areas.

A rain crust is down 40-60cm in the snowpack, and exists up to approximately 2200m. The height of snow at treeline is ~120cm, and down at Rogers Pass (1300m) is 45cm.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Make observations and continually assess conditions as you travel.

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.
