You can trigger an avalanche on any steep slope where you find a cohesive slab resting on weak snow near the ground. Identify and avoid wind-loaded terrain features. Below ridges or in gullies are areas you are most likely to find wind-drifted snow. Look for and avoid smooth rounded pillows of snow. If you experience shooting cracks or collapsing in the snow, or suddenly are on hollow drum like snow consider moving to a different slope or staying on low-angle terrain with no steep slopes above you.
