You can trigger an avalanche large enough to bury you. The most hazardous areas are drifted northerly and easterly slopes near ridgelines and in gully features. Large cornices at ridgetop or a wave-like appearance on the snow surface are signs that a slope holds drifted snow. In areas sheltered from the wind, avalanches may be smaller, but still dangerous. You could trigger an avalanche that breaks on weak layers near the ground where you find more than about 12 inches of recent snow.
