Use extra caution on any slope over 30 degrees. Many slopes are dangerous and may not give you any warning before they release. These conditions are tricky as you can trigger an avalanche from far away or in flat areas below steep slopes. Although you can trigger avalanches in many places, wind-drifted slopes below ridges where slabs are the thickest can produce the largest and deadliest avalanches.
