Points saillants

A reactive persistent weak layer remains the primary concern for the region - especially around treeline

Stick to low-angle slopes and avoid exposing yourself to steep terrain from above

Problèmes avalancheux

  • Wind Slabs

    • Sous la limite forestière
    Probabilité
    Possible - Likely
    Taille
    1–1.5

    Recent snow and wind built small wind slabs near ridgetops and on lee and crossloaded features at upper elevations. Wind slabs could step down to deeper weak layers.

    Probabilité

    1.5–3

    Be aware of the potential for remote triggering and large avalanches due to a persistent weak layer of buried surface hoar or a crust, especially at treeline and forested openings or cutclocks.

Confidence

Moderate

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

Avalanche Summary

Tuesday
A skier remotely triggered a size 1.5 persistent slab at treeline from 50 m away. Several wet loose sluffs up to size 2 were also observed.

Monday
A size 2 natural cornice failure occurred.

Sunday
Numerous natural, explosive, and rider-triggered avalanches were observed, including a size 2.5 avalanche triggered from 3 m away.

Looking forward
Natural avalanches are unlikely, but riders triggering slabs remains possible to likely.

Snowpack Summary

Up to 5 cm of new snow fell on Wednesday and may have formed small new wind slabs in lee areas near ridgetops. The recent snow is covering previously wind-affected surfaces. Solar-facing slopes and lower elevations have a surface crust.

A persistent weak layer of surface hoar or crust is buried 40 to 60 cm, with deeper areas like the Dogtooth Range reporting this layer up to 100 cm deep. Recent persistent slab avalanches have failed on this layer, many triggered in sheltered openings at treeline and below.

The mid and lower snowpack are generally well settled. In shallow snowpack areas, large facets or depth hoar are present at the bottom of the snowpack.

Weather Summary

Mostly cloudy. 0 to 2 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -4 °C. Freezing level 1800 m.

Thursday
Mix of sun and clouds. 30 km/h west ridgetop wind. Treeline temperature -6 °C. Freezing level 1600 m.

Friday
Mix of sun and clouds. 50 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 2000 m.

Saturday
Mix of sun and clouds. 0 to 3 mm of rain at treeline. 60 km/h west ridgetop wind. Treeline temperature 2 °C. Freezing level 2600 m.

Terrain and Travel Advice

  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
  • Be careful as you transition into wind-affected terrain.
