Avalanche Forecast
Regions: Glacier.
If the surface crust is breaking down, it's time to turn around!
Check the winter permit status after 2AM for early opening, to help facilitate an early start.
Confidence
Moderate
Avalanche Summary
Loose wet avalanches to size 2 were observed the past 2 days from steep, rocky, S-facing slopes in the alpine.
Neighboring operations have been observing solar triggered loose snow avalanches out of steep terrain this week, up to size 2. A few natural cornice failures have been observed up to size 2.5
Snowpack Summary
Spring conditions exist everywhere except high north alpine slopes, where settled powder can still be found.
Expect poor travel conditions below treeline. Height of snow at Rogers Pass (1305m) is ~50cm, and even shallower on solar slopes!

Terrain and Travel Advice
- A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
- Avoid travelling on slopes below cornices.
Avalanche Problems
Loose Wet
Possible overnight cloud cover may limit surface crust recovery. Assess the surface crust strength of your line before committing and be mindful of your overhead exposure.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
Cornices
Cornices will weaken with daytime warming. Pay attention to these large triggers lurking on ridge top features throughout the park.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Unlikely - Possible
Expected Size: 1 - 3
