Steeper slopes with wind-drifted slabs resting above weak, collapsible snow layers are more problematic. Small slides can trigger larger ones where the snowpack is less than 3 to 4 feet deep. Common trigger points are near slab margins like rock outcroppings, steep rollovers, and below ridges or cliffs. Consider an alternative route if you notice the snow surface getting stiffer, or if the snow surface looks smooth and rounded. You can find safer travel options below treeline, and on low-angled slopes sheltered from the wind without steep hazards above.
