You can trigger an avalanche where you find wind-drifted snow forming a cohesive slab at upper elevations. Look for and avoid steep slopes with more than about 8 inches of drifted snow. Drifted snow may look wave-like or have a lens shape. Cracking in drifted snow is a sign to move to lower-angled slopes sheltered from the wind.
