Avalanche Summary

You could trigger an avalanche where cohesive slabs of snow sit over weaker snow on slopes steeper than about 35 degrees. Avoid common trigger points, such as convex rollovers, rocky outcrops, or the edges of slopes where the margins of a slab are the thinnest.

Winds have drifted snow into thin slabs at upper elevations. These small shallow wind drifts remain reactive to human pressure in isolated terrain features. Avoid areas of stiff recently drifted snow on steep slopes.
