Kernpunkte

High freezing levels with intense solar could push us into Considerable hazard, pay attention to the temperature!

Please don't get complacent on your search for fresh tracks. The persistent slab problem is worth considering when pushing into bigger objectives.

    Winds have redistributed snow in the Alpine and on lee features at treeline. Expect to find it most reactive at ridge top and in lee or cross-loaded features. This layer will be more reactive if it warms up.

    A weak layer of surface hoar down 50-100 cm is slowly gaining strength. Most likely areas to trigger this problem are in shallow or variable depth snowpacks and unsupported alpine terrain. Use caution in terrain that has not previously avalanched.

Avalanche Summary

A team triggered several explosive controlled avalanches in steep north facing terrain at treeline on Wed. Avalanches were small and triggered soft wind slabs up to 40cm deep.

No new natural avalanches have been observed since Dec 23rd.

A human-triggered avalanche occurred on Video peak Saturday afternoon involving a group of 3, no injuries reported.

Recently significant human-triggered avalanches failing on the Dec 1st surface hoar layer: Balu Pk & Ursus Minor.

Terrain and Travel Advice

  • Avoid steep slopes when air temperatures are warm, or solar radiation is strong.
  • Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
  • Avoid convexities, steep unsupported terrain and rocky outcroppings.
