N.C. Gen. Stat. § 99C-4

The ski area operator shall, prior to the beginning of a competition, allow each competitor a reasonable visual inspection of the course or area where the competition is to be held. The competitor shall be held to assume risk of all course conditions including, but not limited to, weather and snow conditions, course construction or layout, and obstacles which a visual inspection should have revealed. No liability shall attach to a ski area operator for injury or death of any competitor proximately caused by such assumed risk.
