You could trigger an avalanche where recent snowfall drifted on top of older snow layers. Wind-drifted areas commonly exists below ridgelines, in gullies, and on the backsides of convex rolls. Slides can grow larger if triggered from a drifted area around a foot deep. You can identify wind-loaded areas by their smooth, rounded appearance. Shooting cracks and audible collapses are signs of unstable snow, and suggest moving to lower-angle slopes or areas sheltered from the wind. Small avalanches can turn into bigger problems if you get swept over a cliff or stuffed in a terrain trap.
