Avalanche Summary
No new avalanches were reported on Sunday.
On Saturday a rider triggered a large wind slab and was fully buried against a tree. The victim was dug out very quickly by their party.
A widespread natural avalanche cycle occurred on Friday continuing into Saturday. Small to very large (size 3) storm slabs were reported. Also, one large cornice failure was reported on an east-northeast feature.
Snowpack Summary
Strong to extreme wind will likely pickup any soft snow and transport it far downslope. Watch for slabs lower than normal.
In sheltered areas around 50 cm of snow sits on a variety of layers, including surface hoar, crusts, and sugary facets. Wind slabs may take longer to bond because of these layers.
The middle and lower snowpack is generally strong with no weak layers of concern.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Wind slabs are most reactive during their formation.
- Sheltered slopes at lower elevations will offer the safest conditions.
