You can trigger a dangerous avalanche on north, northeast, and east-facing slopes near and above the treeline. The most dangerous areas are the lee sides of a ridgeline or inside of a gully or a couloir where wind-packed, stiff slabs of snow rest on top of old, weak snow from November. You can drastically reduce your chances of triggering an avalanche simply by avoiding these dangerous terrain features.
