Avalanche Summary
On Tuesday warming temperatures in the PM initiated small (size 1) loose wet avalanche on steep south facing terrain. Last week explosives testing triggered several small and large (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
Surface hoar has developed in many areas, while steep, south-facing slopes are warming during the day and forming a thin crust as temperatures drop. In sheltered zones, the upper 40–70 cm of snow remains soft, though wind exposure has redistributed snow in open terrain.
The snowpack is well-settled, dense, and generally strong, with a buried surface hoar layer found 60 to 80 cm below the surface.
Treeline snow depths range from 100 to 150 cm.
Weather Summary

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.
- The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
Problems
