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.

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.
