Avalanche Summary

You could trigger an avalanche if you find a cohesive layer of snow sitting over weaker snow on slopes steeper than about 35 degrees. The most dangerous slopes face northeast and east at upper elevations where winds have drifted snow into thicker slabs. Avoid traveling near common trigger points, such as the edges of slopes where the margins of a slab are the thinnest, convex rollovers, and rocky outcrops.

You can trigger a loose avalanche on steep slopes near rock outcroppings as lower-elevation snow continues to lose cohesion.
