Avalanche Summary

No avalanches were reported on Friday. A few wind slab avalanches were reported on preceding days. They include some large (size 2) natural wind slab avalanches in steep rocky terrain and some small (size 1) explosive and skier triggered wind slabs up to 50 cm thick.

Snowpack Summary

Around 20 cm of snow overlies a hard melt-freeze crust up to around 2000 m. Strong southwest wind redistributed the surface snow, forming wind slabs in lee terrain features. Moist snow or a surface crust may be found up to around 1600 m.

The middle of the snowpack is generally consolidated and sits above weak, faceted snow near the ground.
