The legislative assembly finds that the sport of skiing is practiced in this state by a growing number of North Dakota citizens and nonresidents. Since it is recognized that there are inherent risks in the sport of skiing which should be understood by each skier and which are essentially impossible to eliminate by the ski area operator, it is the purpose of this chapter to define those areas of responsibility and affirmative acts for which ski area operators shall be liable for loss, damage, or injury and those risks which the skier expressly assumes and for which there can be no recovery.
