Avalanche Summary

On Saturday a skier accidentally triggered a large avalanche near Hudson Bay Mountain. It is suspected that this avalanche failed on the facet/crust combination described in our snowpack summary. Check this MIN post for full details.

Snowpack Summary

In general, up to 10 cm of soft, faceted snow overlies hard, wind-affected snow in alpine terrain. Wind-exposed terrain may be scoured down to hard surfaces, while a sun crust exists on south-facing slopes.

In steep, exposed alpine terrain, old, hard wind slabs may sit atop weak faceted crystals and a crust, down roughly 20 to 30 cm from the surface.

The mid and lower snowpack is generally well-bonded and strong.

Weather Summary

Wednesday Night

Clear skies. 10 to 30 km/h northwest ridgetop wind. Treeline temperature -1 °C.

Thursday

Sunny. 20 to 40 northwest ridgetop wind. Treeline temperature -1 °C.

Friday

Mostly cloudy with 0 to 3 cm of snow. 60 to 80 km/h west ridgetop wind. Treeline temperature -3 °C.

Saturday

Cloudy with 0 to 5 cm of snow. 50 to 70 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Carefully evaluate bigger terrain features on an individual basis before committing to them.
  • Use caution when approaching steep and rocky terrian.

Avalanche Problems

Persistent Slabs

Old hard wind slabs over weak sugary facets on a hard crust could still be human-triggerable in isolated locations, mainly in rocky, steep alpine terrain.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
