Tree Well & Deep Snow Safety
What is a tree well?
It's the void area of loose snow surrounding the trunk of a tree after a heavy snowfall. Tree wells are deceptive, as you cannot see the unstable snow around a tree.
It is easy to fall into a tree well. Once you fall in, the snow surrounding the tree piles on top of the unlucky victim and traps them underneath. Since most people fall headfirst into Tree Wells, they can be more dangerous than avalanches.
The chance of surviving an encounter with a tree well is extremely low; in two experiments performed in Canada and the U.S., volunteers were temporarily placed in tree wells and only 10% of them were able to free themselves.
So listen up! Here are some tips to avoid what many unlucky victims meet every year.
Tips to Avoid Tree Wells
Tree wells are encountered off groomed runs and are most risky after heavy snowfalls, when low-hanging branches shelter the base of the tree's trunk. As in all cases, the best way to avoid these dangerous obstacles is to stay on groomed, ski-patrolled runs.
If you must venture off the beaten trail, however, here are some tips to reduce your risk:
- Ski or snowboard with a partner, and keep them in sight. It may hurt your ego to slow down every now and then, but waiting for your partner is worth the extra two minutes. Riding and skiing with a partner is always a safer way to go.
- Avoid getting too close to trees, especially after heavy snowfalls. Avoid deep snow and tree areas when possible.
- Assume that all trees have tree wells. You can never be too careful. Tree wells are often hidden, so avoid trees that look like their branches can shelter against snow.
- Do not leave to get help, it will not arrive in time. People have been known to suffocate within 15 minutes of being trapped in a tree well. Get your partner's head above the snow and create an airway. Yell for help and hopefully it will come.
- Ski and ride defensively. Take a step back and know your surroundings.
- Stay calm. The more you fight, the deeper you will be buried. Create a breathing space and wait for help. If you are alone, be conscious about your surroundings and move strategically to free yourself.
