Triple Black Diamond Terrain
This season, Big Sky Ski Patrol has designated certain trails as triple black diamond to increase guest education and awareness of the risks of skiing high alpine, high consequence terrain. The methodology for designating trails as triple black diamond includes: exposure to uncontrollable falls along a steep, continuous pitch, route complexity, and high consequence terrain. The triple black diamond trail rating is used as a communication tool to encourage conservative skiing with a focus on skiing in control.
