You can trigger an avalanche in wind-drifted snow on slopes steeper than 30 degrees. Avalanches will be larger where you find more than about one foot of drifted snow. If you see recent signs of avalanches or encounter snow that is stiff and has smooth, rounded, pillow-like features you have found a problematic slope. Lower-angle wind-sheltered terrain offers safer travel options.
