Points saillants

Remain cautious if entering extreme and high-consequence terrain.

The best and safest riding will be in areas sheltered from wind-effect where snow remains soft.

Confidence

Moderate

Avalanche Summary

Several small solar-induced loose sluffs running out of steep rocky terrain were observed on Sunday afternoon. Otherwise, no recent slab avalanches have been reported.

Reports have been very limited, If you head into the backcountry, please consider submitting a MIN post.

Snowpack Summary

Surfaces have seen extensive wind-effect in alpine and exposed treeline terrain. In wind-sheltered terrain, the upper snowpack remains generally soft and faceted, with new surface hoar growth reported in some areas. A hard melt-freeze crust from mid-January may exist approximately 50 to 100 cm deep, but is not considered a concern at this time. The lower snowpack is generally consolidated and strong.

Terrain and Travel Advice

  • Periods of low danger may be a good time to increase your exposure.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
