Avalanche Summary
A couple of skier-triggered avalanches surprised a ski touring group on Saturday. Both avalanches were reported as size 2 and occurred on a northeast, alpine slopes just below a rocky ridge top.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
Snowpack Summary
On the surface is a recently formed melt-freeze crust, observed up to 2000 m, and may exist higher by Monday morning. Roughly 10 to 20 cm of dry snow beneath the crust is settling over various, wind-affected surfaces created during the recent extreme cold period.
The mid and lower snowpack consists of various crusts and layers of facets or surface hoar. Reports indicate these are not currently a concern.

Terrain and Travel Advice
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
- Closely monitor how the new snow is bonding to the crust.
