Weak snow from January lies 2-3 feet below the snow's surface. Though this drought layer has gained strength with time, triggering a large and widely propagating avalanche remains possible, especially in very steep terrain above about 8,000'. This problem continues to deserve respect, especially in high consequence terrain and places where the slab may be thin enough for the weight of a person or sled to hit the weak layer. There may not be a warning sign bfore triggering this layer as the slab above has grown stiff and stubborn.
Cornice Fall: Large triggers such as a falling cornice could trigger a larger avalanche. While unlikely, it's a good idea to give cornices some space.
