You can trigger an avalanche where you find more than about eight inches of drifted snow resting over old weak snow. The most dangerous slopes face north to northeast through east near and above treeline. Avalanches may break wider than you anticipate. Shooting cracks in drifted snow are a sign you should move to lower-angle or wind-sheltered terrain. Even a small, shallow avalanche can have dire consequences if you get carried over rocks or logs.
