Avalanche Summary

You could trigger avalanches where a cohesive slab of recent snow sits on top of weak snow. The most dangerous slopes are where winds have drifted snow into thick, stiff slabs. Drifted snow may feel firm, sound hollow, or crack under your weight. Slopes less than about 35 degrees steep offer safer travel options.
