Tree well

A tree well is a void or area of loose snow that forms around the base of a tree, typically in coniferous forests. These wells are most commonly found in areas with deep snowpack, such as mountainous regions. Tree wells pose a significant hazard to skiers, snowboarders, and snowshoers, as they can lead to entrapment and suffocation.

Formation

Tree wells form when the branches of a tree prevent snow from consolidating around the trunk. As snow accumulates, it creates a depression or well around the base of the tree. The depth and size of a tree well can vary depending on the amount of snowfall, the type of tree, and the density of the forest.

Hazards

Tree wells are particularly dangerous because they are often hidden from view. When a person falls into a tree well, the loose snow can collapse around them, making it difficult to move or breathe. This situation is known as a snow immersion suffocation (SIS) hazard. Victims can become trapped and may require immediate assistance to avoid suffocation.

Prevention and Safety

To avoid the dangers of tree wells, it is important to follow these safety tips:

• Always ski or snowboard with a partner and keep them in sight.
• Stay on groomed trails and avoid areas with deep, unconsolidated snow.
• Carry appropriate safety equipment, such as a whistle and a shovel.
• Be aware of the signs of tree wells and avoid skiing or snowboarding too close to trees.

Rescue

If someone falls into a tree well, it is crucial to act quickly. The following steps can help in a rescue:

• Call for help immediately.
• Try to keep the victim calm and reassure them.
• Carefully dig around the victim to create an airway and free their limbs.
• Avoid pulling the victim out by their limbs, as this can cause further injury.
