Confidence
High
Avalanche Summary
No new avalanches have been reported at the time of publishing on Friday.
Snowpack Summary
The upper snowpack is comprised of crusts, settled powder, unconsolidated facets, and old wind slabs. Beneath lies a thin snowpack, with weak facets near the bottom, especially in alpine terrain.
Snowpack depths at treeline average 50 to 120 cm with significant regional variability.

Terrain and Travel Advice
- Use caution on large alpine slopes, especially around thin areas that may propagate to deeper instabilities.
- Be especially cautious near rock outcroppings, on steep convexities and anywhere the snowpack feels thinner than average.
Avalanche Problems
Deep Persistent Slabs
A layer of weak facets near the ground may be triggerable by riders. Especially in shallow, rocky alpine terrain where it is not covered by a thick crust.
Aspects: All aspects.
Elevations: Alpine, Treeline.
