    Watch for fresh wind slabs from southwest winds and Saturdays snowfall. Take care around ridge crests and wind loaded features. Older wind slabs buried by the fresh snow may still be reactive to human triggers.

Avalanche Summary

There have been no reports of recent avalanche activity within the last 3 days.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Wind affected snow can be found at higher elevations, with recent storm totals of 10-20 cm sitting over a crust below 2000 m.

The snowpack below is considered settled. Weaker layers exist but with thick crusts sitting above, triggering avalanches on these layers is unlikely.

Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m.
