You can trigger a slab avalanche on many steep slopes. In wind-drifted terrain, one might break three or more feet deep. You can trigger these from below or next to steep terrain, and they can entrain surprisingly lower-angle slopes around their edges. Make conservative choices and give avalanche paths a wide berth. Look for safer options on wind-sheltered south or southwest-facing terrain.
