Skiing and snowboarding off the groomed runs and in deep powder snow is one of the most exciting and appealing parts of our sport. If you decide to leave the groomed trails, you are voluntarily accepting the risk of falling into tree wells or deep snow and suffocating.
A deep snow or tree well accident occurs when a rider or skier falls into an area of deep unconsolidated snow and becomes immobilized. The more the person struggles, the more entrapped in the snow they become. Deaths resulting from these kinds of accidents are referred to as a NARSID or Non-Avalanche Related Snow Immersion Death. Fortunately, these types of accidents are preventable.
