You could trigger a large and dangerous avalanche. You will need to be on or near a steep slope at upper elevations. Common trigger points include rock outcroppings, steep rollovers, below ridges, and cliff bands. Avalanches on previously drifted slopes could step down to deeper weak layers, triggering a larger and more dangerous slide. Use caution on steeper slopes where the snow surface transitions from soft to stiff or in places with a smooth, rounded appearance.
You can find safer riding options below treeline or on low-angled, wind-sheltered slopes without steep overhead hazards.
