You can easily trigger an avalanche large enough to injure or kill you on many steep slopes, especially if the path previously slid. Before triggering an avalanche, you may not see obvious signs of instability, like cracking or collapsing within the snowpack. You can trigger an avalanche from far away or the runouts of steep slopes. Although you can trigger avalanches in many places, wind-drifted steep slopes directly below ridgetops can produce the largest and deadliest avalanches.
