Avalanche Summary

No human-triggered avalanches have been reported in the past week. Explosives have triggered several size 1 to 2 slabs, mostly on south and southwest aspects. Old storm snow is generally well-bonded, except possibly in areas with recent wind loading.

Snowpack Summary

Last week's 40 to 70 cm of snow remains soft in sheltered areas but has been redistributed by wind in exposed terrain.

The snowpack is generally strong, with some buried surface hoar 60 to 80 cm deep and crusts near the ground showing no recent avalanche activity.

Treeline snow depths range from 100 to 150 cm.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
