A "no fall zone" in skiing refers to an area where falling could have major consequences, such as falling off a cliff and dying. It is a term used to describe a section of a ski run where a minor fall could result in serious injury or death. In mountaineering, a no-fall zone is an area where a fall could be fatal, and it is often marked by steep, exposed terrain. In skiing, a no-fall zone is typically an area with steep, narrow terrain where a skier must maintain control and avoid falling to avoid serious injury or death. Some skiers take precautions to ensure their bindings are secure before skiing in a no-fall zone.
