Avalanche Summary

The most dangerous slopes are where the wind has drifted snow into thick slabs. These drifted slopes are most likely found directly below ridgetop. 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.
