In sintesi

Conditions are generally safe, but avalanches may still occur.

Consider what is below you before committing to your line.

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–3

    Cornices are large and overhanging. Avoid travelling underneath them.

Confidence

High

  • We are confident due to a stable weather pattern.

Avalanche Summary

Explosive control on cornices continues to produce large results. This is the time of year when cornices are more likely to fail naturally, too.

A large (size 3) cornice collapsed naturally on Tuesday near The Bugaboos, as well as one small skier accidental wind slab that occurred below a cornice near Golden.

Snowpack Summary

A thin crust has formed on south-facing terrain from recent solar radiation and overnight refreeze. On shaded aspects, 10 to 15 cm of recent snow overlies wind-affected, consolidated snow.

Below this, 30 to 70 cm of snow overlies a thick crust from the recent atmospheric river, which extends up to at least 2200 m.

Various persistent weak layers may still exist in the top 150 cm of the snowpack and in shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack. Large triggers, like falling cornices, may be able to trigger these layers at upper elevations where the crust below the recent snow is thin or absent.

Terrain and Travel Advice

  • Avoid travelling on slopes below cornices.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
