Avalanche Summary

On Thursday and Friday, riders triggered small (size 1-1.5) wind slab avalanches in lee features at upper elevations. (Slidetastic 5040 MIN)

On Friday morning, explosives triggered several small wind slab avalanches from steep northerly terrain.

Snowpack Summary

Wind has impacted 20 to 40 cm of settling snow from the last few days at upper elevations. Below 1500 m, surfaces may be moist or crusty.

Recent snow covers 50 to 80 cm of older snow which is bonding well to an underlying crust and lower snowpack. Snowpack depths at treeline average 200 to 300 cm.
