Avalanche Summary
No new avalanches were reported in this region on Friday.
Snowpack Summary
Convective flurries on Sunday and southwesterly winds may form small wind slabs sitting on slippery crusts on lee features below alpine ridgetops. Crusty surfaces exist on all but north facing terrain at upper elevations.
Cornices are large, looming, and capable of triggering large avalanches when they fail.
The mid-pack is firm and well settled. Some faceted snow and a decomposing melt-freeze crust can be found near the base of the snowpack.Â
 Glide cracks releasing as full depth glide slab avalanches become more common in the spring and are extremely difficult to predict. Best practice is to avoid slopes with glide cracks.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Wind slabs may be poorly bonded to the underlying crust.
- Be alert to conditions that change with elevation and sun exposure.
- Avoid exposure to slopes that have cornices overhead.
