## Summary
Tree wells are close to zero risk on a groomed piste and a real one on a powder day in the trees. The most quoted figure in this field says 72 percent of people who died were skiing with a partner who was not watching. That number is press-relayed and we could not verify who counted it, but the failure it describes is what both deepsnowsafety.org and Austria's KFV build their guidance around. Here is how to turn it into a protocol your kids can actually follow.
## Overview
Nobody mentions tree wells at the rental shop. They are not on the piste map, not in the lift pass small print, and not in the ski school welcome talk. Then a news story turns up in January, and you spend the rest of the week watching your kids vanish into the trees at the edge of the run. So, the answer first. For most family ski trips, this hazard is close to zero. It needs deep, loose, recent snow, and it needs trees. On a groomed piste, in a thin snow year, or above the treeline, it is not t...
## Comparisons
### Where this risk is real, and where it plainly is not
| Where you are | Is this a real risk? | What to do about it |
| --- | --- | --- |
| Groomed, marked piste at any resort | No. Effectively zero. | Nothing. Ski. This hazard needs deep unconsolidated snow, and a groomed piste by definition does not have any. |
| Above the treeline, on open high Alpine terrain | No trees, so no tree wells. | Other hazards live up there (whiteout, wind, avalanche terrain off-piste), but not this one. If your day is spent above the trees, you can put this particular worry down. |
| Thin snow year, firm or spring snow, an icy Alpine February | Very low. | Tree wells need loose new snow deep enough to sink into. Settled, wind-packed or refrozen snow does not swallow a skier. |
| Marked run with trees along the edge, after a heavy snowfall | Low, but not zero if a child cuts a corner into the trees. | Ski the middle third of the run. Make "stay off the tree side today" a rule for the day rather than a suggestion. |
| Glades and tree runs during a storm, or while the new snow is still loose and deep | Yes. This is the one. | Full pair protocol, whistles, continuous visual contact, or do not go into the trees at all that day. |
| Tree runs at a high snowfall resort on a big day | Highest family exposure, and it is usually the teenager rather than the toddler. | Have this conversation before the trip, not at the top of the run. If Japan is the trip you are planning, start with our Japan family guide. |
| Beginner and intermediate ski school groups on marked pistes | No. | Those lessons run on marked, patrolled terrain, which is not where these incidents happen. Advanced lessons, off-piste clinics and guided tree sessions are a different product, so ask what the terrain will be when you book. |
## Key Recommendations
### The family tree protocol, in six rules kids can actually follow
- **Pair up out loud, by name, before you drop in**: Not "stay together as a family". Groups diffuse responsibility; pairs do not. Say it at the top of the run: "Mia, you are with Dad. Sam, you are with me." Each person now has exactly one human whose job is to know where they are. If someone has no partner, they do not ski the trees, they ski the piste and meet you at the bottom.
- **Leapfrog: never both moving at the same time in trees**: One skis, one watches. The watcher does not move until the skier has stopped and is visible. Then they swap. It feels slow for about four minutes and then it feels normal, and it is the single change that converts "skiing together" into the thing that actually protects you.
- **Stop where you can still see them, not where the view is nice**: The stopping point is chosen by line of sight, never by scenery or convenience. If the stand of trees between you means you cannot see your partner's stopping spot, you have gone too far and you side-step back up. That is the consequence: a bit of climbing, versus a partner nobody is watching.
- **Give your kids the sentence, not the lecture**: Children do not retain risk briefings, they retain lines. The sentence we recommend: "If I cannot see you, I stop and I shout." Say it on the lift, have them repeat it back, and make it non-negotiable that stopping is never the wrong call. A child who freezes and yells has done exactly right, even if it turns out you were fine and just behind a tree.
- **A whistle on every zipper pull, before the trip**: KFV's guidance for deep snow explicitly includes carrying a whistle and using it to attract attention if you are trapped. A whistle carries when a buried voice does not, and it needs no grip strength, no gloves off, and no phone screen. Zip-tie one to each child's jacket pull at home. It is the only purchase this article asks you to make.
- **Ban the phrase "meet you at the bottom" on any treed run**: That plan is how a missing person stays undiscovered for the length of a lift ride plus a chairlift back up. On a powder day in the trees, the meeting point is not the bottom of the run, it is the next stopping point you can both see.
## Checklists
### The powder day family checklist
- [ ] Zip-tie a whistle to every family member's jacket pull before you leave home, kids included.
- [ ] Look at the overnight snow before you go up. This protocol is for loose new snow deep enough to sink into, the metre-plus sink depths KFV describes. On firm, settled or spring snow it can stay in your pocket.
- [ ] Name the pairs out loud on the chairlift, by name, before the first treed run of the day.
- [ ] Agree the sentence with each child and have them say it back: "If I cannot see you, I stop and I shout."
- [ ] Agree the leapfrog rule: one skis, one watches, nobody moves until the other is stopped and visible.
- [ ] Delete "meet you at the bottom" from the day's vocabulary for any run with trees in it.
- [ ] Save the local emergency number and the resort patrol number in every phone that is coming up the mountain.
- [ ] Give teenagers the rule in the form other teenagers respect: pairs and leapfrog, because that is what good tree skiers do.
- [ ] Decide in advance which runs are off the menu today, and say it before the lift, not at the entrance to the glade.
- [ ] Balaclavas or neck gaiters on for storm days, and skis off at the bindings if anyone does go in.
## Frequently Asked Questions
**Q: Is my 6-year-old at risk of falling into a tree well?**
A: In almost all realistic family situations, no. Tree wells need deep, loose, recent snow and conifers, which is off-piste or gladed terrain, not where a six-year-old skis. Beginner and intermediate ski school groups operate on marked, patrolled pistes. The family member with meaningful exposure is a confident older child or teenager who follows friends into the trees on a powder day.
**Q: Do tree wells happen in Europe, or is this only an American thing?**
A: They happen in Europe. Austria's KFV (Kuratorium für Verkehrssicherheit), the country's state-mandated accident prevention body, publishes guidance on deep snow suffocation and logged six deaths in Austria between 2018 and 2021 (victims aged roughly 24 to 39). The hazard is simply discussed more in North America and Japan than it is in Europe. Why that is, we can only guess at, and we are not going to pass a guess off as a fact. If you ski Austrian or Swiss tree runs after a big dump, the same rules apply.
**Q: Can you fall into a tree well on a groomed run?**
A: No. A groomed piste has compacted, machine-worked snow that will not swallow a skier, and there are no conifer trunks in the middle of it. The risk lives in the untouched snow at the sides and in the glades. This is why we say plainly that most family ski weeks have effectively zero exposure to this hazard: telling you when a fear does not apply is the point.
**Q: How long does someone have if they fall in headfirst?**
A: We are not going to give you a number of minutes, because the sources we can verify do not give one and inventing a countdown would be worse than admitting the gap. What deepsnowsafety.org says is that without a partner immediately present, death can occur as fast as drowning, and that in research experiments recreating these immersions 90 percent of participants could not extricate themselves without help. That combination is why the response has to come from someone already standing there, not from a phone call.
**Q: Should I buy my child an avalanche beacon or an airbag pack for tree skiing?**
A: Not for this. A transceiver, a RECCO reflector and an airbag all assume that someone already knows a person is missing and is actively searching within minutes. The failure here is that nobody knew to look, which is exactly what the most quoted figure in this field describes, with the caveat that we could not verify who counted it. Fix the watching, and the hardware becomes unnecessary. Skip the watching, and the hardware arrives too late. A whistle is the one purchase worth making.
**Q: What do I actually say to my kids so they remember it?**
A: Give them a sentence, not a briefing: "If I cannot see you, I stop and I shout." Then name their partner out loud before every treed run, and make stopping always the right call, even when it turns out you were just behind a tree. Children retain lines and roles. They do not retain risk statistics, and you should not be reciting fatality numbers to a seven-year-old.
**Q: Are the tree well statistics reliable?**
A: Partly, and we would rather say so. The count of roughly 90 in-bounds US deaths since 2001, averaging four to five a season, is Paul Baugher's own logbook of publicised cases at deepsnowsafety.org, and we reached it through an Outside magazine writeup rather than an official registry. The 72 percent no-visual-contact figure is weaker still: we found it in Steamboat Pilot & Today, credited to the Northwest Avalanche Institute, with no period or denominator published, and we could not confirm that body as an established research organisation. Read both as directional and as a floor rather than a ceiling. The mechanism your protocol is built on is not in dispute, and is described the same way by deepsnowsafety.org in the US and KFV in Austria.
