You can trigger an avalanche on north, northeast, and east-facing slopes above the treeline where wind-drifted cohesive slabs of snow now rest on weak snow. If you notice signs of instability such as shooting cracks or collapsing in the snow consider moving to low-angle terrain or a different aspect. Below the treeline, the snow is generally too thin to trigger a dangerous avalanche.
