Tree Well and Deep Snow Safety

Skiing and snowboarding off the groomed runs and in deep powder is one of the most exciting and appealing parts of the sport. However, if you decide to leave the groomed trails you are voluntarily accepting the risk of a deep snow immersion accident. A deep snow or tree well immersion accident occurs when a skier or rider falls into an area of deep unconsolidated snow and becomes immobilized and suffocates. Deaths resulting from these kinds of accidents are referred to as a NARSID or Non-Avalanche Related Snow Immersion Death.

NSAA has an excellent caution sign for resorts to use to warn skiers about the hazards of tree wells. This sign was designed and developed by Dan Lemmer and Johnny Sawyer from Steamboat, where they use this sign on their mountain (great job, Steamboat!) Ski areas are welcome to download this design and have signs made to fit the conditions at their resorts, either for on-mountain signage, printed trail maps, or other mountain media.

The sign is downloadable here.

Become educated on how to reduce the risk of NARSID through your own action and awareness. ALWAYS ski or ride with a partner. The website www.treewelldeepsnowsafety.com is intended to assist all skiers and riders in learning about the risks and prevention of deep snow immersion accidents.
