Avalanche Summary

You could trigger an avalanche where cohesive slabs of snow sit over weaker snow on slopes steeper than about 35 degrees. Recently wind-drifted areas are easier to trigger. Wind-drifted areas often feel stiff or have a wave-like appearance. Avoid common trigger points, such as convex rollovers, rocky outcrops, below cliff bands, or the edges of slopes where the margins of a slab are the thinnest.

At lower elevations, the surface slab continues to deteriorate. You can trigger a loose avalanche on steep convex features and near rocky outcroppings where the surface snow has lost cohesion.
