Points saillants

Sheltered, shaded terrain holds the best riding and the lowest avalanche danger.

Space out to avoid exposing multiple people to a slope at once, and give cornices a wide berth.

Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2

    Spotty, convective snowfall and periods of moderate wind may form small, reactive pockets of wind slab. If your area hasn't gotten new snow in the past couple days, this problem is unlikely.

  • Cornices

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1.5–3

    Cornices are large and fragile. Even a small period of sun and warming may be enough to cause a cornice to fail.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

Both Thursday and Friday, large to very large (size 2-3) natural storm slab avalanches were reported near Anderson Lake.

The most recent avalanche on a persistent weak layer was reported on Monday, March 23 when an explosive triggered cornice fall stepped down to basal facets in a steep, rocky start zone.

Snowpack Summary

Expect to find 30 to 50 cm of settling snow over a thick and hard crust below about 1900 m, and old wind-affected snow at upper elevations.

Steep south facing slopes may be crusty or moist depending on time of day and sun exposure.

Two older crusts (1-1.5 m deep), buried in early February and March previously produced large to very large avalanches, but they seem to have gained strength and are not a current concern.

Weather Summary

Monday Night

Mostly clear skies. Ridgetop winds increasing through the night to 30 km/h from the southwest. Treeline temperature -9 °C.

Tuesday

Mix of sun and clouds. 30 km/h southwest ridgetop wind. Treeline high -5 °C. Freezing level rising to 1500 m.

Wednesday

Mix of sun and clouds. 2 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -5 °C.

Thursday

Mix of sun and clouds. 1 to 5 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
