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 at upper elevations. Drifted snow may feel firm, sound hollow, or crack under your weight. You can find safer travel options in areas sheltered from the wind or on slopes less than about 35 degrees in steepness.
