DID YOU KNOW?
Tree well and snow immersion accidents account for up to 20% of fatalities in public ski areas. [1]
KNOW THE RISK
- While avalanches get more attention, tree wells and snow immersion can be just as deadly. [1]
- Tree wells are deep, soft pockets of unconsolidated snow that form around the base of conifer trees like pines, firs, and spruces. [1]
- Skiers, snowboarders, and snowmobilers are at highest risk of falling into these wells headfirst and becoming trapped. The loose snow can collapse in around the body, making escape extremely difficult — even for strong athletes. [1]
MITIGATE THE RISK
1. Don’t Go Alone in Deep Snow
- Always ski or ride with a partner in deep snow terrain, and keep each other in sight. Carry a shovel and maintain visual contact. [1]
2. Stay Away from Tree Bases
- Keep your distance from large trees with low-hanging branches, which often conceal deep, unstable wells. [1]
3. If You Fall In, Stay Calm
- Panic burns oxygen and increases the chance of suffocation. Try to create an air pocket and signal with movement or sound. [1]
4. Rescue Smart
- If a partner falls into a tree well, approach from the downhill side and dig carefully to avoid further collapse. [1]
WINTER RECREATION REMINDER
Tree wells are invisible until you’re in them. By skiing with a buddy, staying alert, and avoiding tree bases, you can dramatically reduce your risk. Snow immersion is silent — but preventable.
