Avalanche problems
Avalanche Summary
Northwest to north through east-facing slopes at upper elevations are the most dangerous for triggering avalanches. On these slopes, recent snow settled and was wind-driven into cohesive slabs on top of old, weak snow near the ground. Take note of recent avalanche activity and other signs of instability, including cracking and collapsing, as indicators of slopes you want to avoid.
You can find safer traveling options on slopes that didn't harbor old snow before this past storm or slopes less than 30 degrees.
