What is a tree well and why are they dangerous?
Tree wells can range from an arm’s length to double the height of an adult skier. Tree wells are dangerous because they are essentially hidden pockets of air that can cause injury from falling, and result in a skier being quickly surrounded by snow that blocks their airways.
How deep can tree wells get?
Formation. A tree’s branches shelter the area around its trunk from snowfall. If the snow is deep enough, there is a significant void or area of loose snow underneath the branches around the trunk. Such wells have been observed as deep as 20 ft (6 m).
What happens when you fall into a tree well?
Tree wells are dangerous due to snow-immersion suffocation (SIS). This snow, much like an avalanche, can trap the skier and leave them without fresh air to breathe, thus leading to suffocation. Most tree well/SIS accidents have happened during or just after big snow storms or storm cycles.
How long can you survive in a tree well?
People who get caught in tree wells can sometimes find air pockets and survive up to an hour, but for many their survival time is closer to 15 minutes.
Are tree wells necessary?
A tree well provides space around the trunk of a tree that is free of grass or weeds and is often covered with mulch. Tree wells, when done correctly, contribute to a tree’s overall health by providing the following benefits: Preventing trunk damage by lawn mowers and weed eaters. Regulating soil temperature.
What is the purpose of a tree well?
Can you drown in deep snow?
A tree well/ snow immersion suffocation accident can happen when a skier or snowboarder falls – usually headfirst – into a tree well or deep loose snow and becomes immobilized and trapped under the snow and suffocates. Breathing becomes difficult as the loose snow packs in around you.
What is a tree well death?
From the Ski Whitefish website: 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.
How many people have died in tree wells?

What do you put in a tree well?
Another type of tree well involves adding a “breathing layer” to the soil above the tree’s roots before adding the new grading. This is accomplished by laying down coarse gravel in a layer on top of the existing grade and then placing heavy straw or landscaper’s matting down before adding the new soil on top.

The risk of encountering one is greatest during and immediately following a heavy snowstorm.
What happens if you fall into a tree well?
This creates a void or area of loose snow below the branches and around the trunk that is dangerous to any hikers, snowshoers, skiers, and snowboarders who fall into them. If someone lands in such a well, often as a result of a fall, it can be too deep for them to climb up the surrounding loose snow before they are buried.
What is a tree well in the snow?
A tree well is a void or area of loose snow around the trunk of a tree enveloped in deep snow.
