It is recognized that skiing as a recreational sport is hazardous to skiers, regardless of all feasible safety measures which can be taken. Each skier expressly assumes the risk of and legal responsibility for any injury to person or property which results from participation in the sport of skiing including any injury caused by the following: variations in terrain; surface or subsurface snow or ice conditions; bare spots, rocks, trees, or other forms of forest growth or debris, lift towers and components thereof; pole lines; and snowmaking equipment which are plainly visible or are plainly marked in accordance with the provisions of section 53-09-03. Therefore, each skier shall have the sole individual responsibility for knowing the range of that skier’s own ability to negotiate any slope, trail, or aerial passenger tramway, and it is the duty of each skier to ski within the limits of the skier’s own ability, to make reasonable control of speed and course at all times while skiing, to heed all posted warnings, to ski only on a skiing area designated by the ski area operator, and to refrain from acting in a manner which may cause or contribute to the injury of anyone. The responsibility for collisions by any skier while actually skiing, with any person or object, is solely that of the individual or individuals involved in such collision and not that of the ski area operator. No person may:

1.    Unless authorized by the ski area operator, place any object in the skiing area or on the uphill track of any aerial passenger tramway which may cause a passenger or skier to fall.

2.    Cross the track of a t-bar lift, j-bar lift, platter lift or similar device, or a fiber rope tow except at a designated location.

3.    Fail to wear retention straps or other devices to help prevent runaway skis.
