You could trigger avalanches where you find cohesive slabs of snow sitting on top of weak snow, especially in areas of wind-drifted snow at upper elevations. The most dangerous slopes face north to northeast through east, but remain suspicious of steep slopes that face other directions if they feature stiff snow at the surface. Drifted snow feels stiff and may crack under your weight. If you feel collapsing or cracking, you can choose safer terrain by moving to slopes less than about 35 degrees in steepness.
