Yes, this is a very serious topic.
Thank you for posting it.
As many of you know, we lost Paul Melby to a tree well at Crystal last winter.
Every year we lose and handful this way.
If this guy had been solo he'd have likely also been a goner.
One's chances are not even great if skiing with a partner and the tail gunner goes in behind a fast skiing leader.
I think it might have been the Scotsman that had a bad scare with his son over a such an incident.
I'd like some to some research on the most effective methods to deal with these situations, both from the victim and the rescuer’s perspectives.

Seems like the best method for extraction would be to dig with the same technique as someone buried in an avalanche until you can get enough leverage to pull them out. It could be more complicated if its a steep area and they fell in on the uphill side though. For me personally, feeling someone holding onto my ankle would help me stay a lot calmer. It might also be best to leave the ski on until ready to pull unless its impeding digging. I guess you could always stuff a backpack down a tree well to practice.

Digging along the edges of the victim's body doesn't work well. If anything it just encourages the body to slide farther into the hole. I think it may be better to start a large hole next to the tree well and then enlarge it sideways until the victim's whole body is exposed. You could get a lot more shovelers working that way, move a lot more snow out of the way, and you wouldn't be restricted by the presence of the tree.
I think developing some "strategic shoveling" guidelines for tree wells would be very valuable to the outdoor community.
This video made me really appreciate the value of carrying a shovel any time you're powder skiing, even if you don't have a beacon (often the case in a controlled ski area). I think about my son and his friends as they get more interested in deep snow.

Looking at the video, from roughly the 0:51 mark: the victim is skiing straight ahead, with his hands over his head, and right towards a single tree in the middle of a large open area. No other trees are within several yards in any direction, like maybe 10+ yards. It's hard to see, so I eventually viewed the 720p HD version at full-screen, and kept hitting the pause button to try to figure out what happened.
Can anyone figure out what is going on? How does he fall, and how does he end up inverted? Something appears to be just not right with what happens. Did he crash over his tips, or fall backward over his tails? He is completely inverted head-down when the camera arrives, and the tail of his one remaining ski is pointing downhill. Skiing with your hands over your head, directly towards the only tree in the middle of a large open area, and crashing into a tree well -- not good.
Just as with avalanches, the MOST important thing is to avoid creating an accident and becoming a victim at all -- rescue skills and techniques should be secondary. Skiing in a manner to avoid tree well accidents should be a priority. I'd like to learn more about how to do that. Have I been doing some things wrong all along, but just gotten lucky enough to avoid falling into a tree well in deep-snow conditions so far? I don't know -- although I've never done anything like what it appears this guy did.
One other unrelated comment: not sure if others feel the same way, but I felt a strong visceral dislike for the attitude of the cameraman throughout the entire incident.

Am I mistaken? Did they take their gloves off that fast but remain standing there watching?
I must admit at first I thought it was staged the way they happened upon him.
Scary stuff indeed.
I was once stuck in a tree well in the sidecountry of Stevens ski area years back and was on my back sinking in. I was on tele gear and as I tried to reach for the ski closest to me I sunk deeper. It was a scary place to be but fortunately I was able to yell for help until someone found me. Had I been in it face first it would have been a very different outcome.

I'd have to agree with Lowell that the shoveling could have been much more effective. Strategic shoveling is the best way to extract someone from a tree well. It is even more effective in steep terrain.
I think this is often an overlooked hazard in the backcountry (and frontcountry for that matter). Last year there were more tree well fatalities in the Canadian mechanized ski industry than avalanche fatalities.

Of course there are more people in the mountains these days, but it seems like we should have heard of incidents like this at least occasionally in the old days. (It would be interesting to ask Paul Baugher about this. He's the Expert in my book.)
I suspect that it's related to fat boards making soft snow more accessible. I know somebody's going to say that I'm always making up historical trends, but it seems to me that this is a real one. Am I imagining it?

I went in a tree well once. It happened so fast I don't think it would've mattered where I was holding my hands or how I was skiing at the time. I was able to walk my hands up the wee little tree trunk until I was clear of the snow, but it exhausted me and I knew I'd been lucky. This was about 10 or 12 years ago, and although I'd only been skiing a couple of years at the time I was sure aware of tree well safety before this happened.
Like others, I'm not impressed with the "teamwork" on display, and I sure wouldn't be advertising my corporate consulting business using this video.
Edit to add: I remember seeing a video of Ben Manfredi (I think) skiing into a tree well, and my memory is of an outstanding skier totally in control who within a split second was upside down with his skis on the surface next to a tree. It's possible that it's hard to imagine how quickly this happens unless you're looking directly at it.

Last year there were more tree well fatalities in the Canadian mechanized ski industry than avalanche fatalities.
That's a remarkable statement. What does "mechanized ski industry mean? Does it mean chairlifts only, or also include cat skiing and helicopters?
Here are some good references about snow immersion accidents:
Paul Baugher (2007):
www.nwac.us/media/uploads/pdfs/Non-avala...rsion_fatalities.pdf
Christopher Van Tilburg (2010):
www.docwild.net/files/WEM63.pdf
Here's a quote from the introduction in Paul Baugher's article:
... in the period from 1985-1995 the NARSID risk was ten times greater than the risk of an avalanche burial at a U.S. ski area. This study shows that between 1990/91 and 2005/06, the risk of NARSID at U.S. ski areas has become fifteen times greater. That suggests that this risk trend is steadily increasing.
Here's another good quote, from Paul's conclusion:
In bounds avalanche fatalities are virtually disappearing while the trend for out of bounds avalanche has remained relatively flat even though there is much more out of bounds traffic. This reflects diligent ski area risk management efforts in the form of avalanche control, boundary management policies, and robust public education. However, also in the last sixteen years, there has been a trend in risk at U.S. and B.C. ski areas that has remained “under the radar”. This study was designed to investigate; recognition of the risk, key factors in the snow immersion phenomenon, and prevention strategies. The preliminary findings are: The greatest single component of snow immersion risk is that it is substantially underappreciated. The risk of snow immersion accidents (NARSID) is on the increase....
So here's my theory: Snow immersion accidents have increased, in part, because of more efficient avalanche control, which is opening deep snow areas sooner than in the past. Also, fat skis and snowboards have made deep snow easier to ski and therefore more attractive. Fat boards also enable recreationists to ski faster because they float better and are easier to turn. The new gear gives skiers and boarders more control, generally, but because they are going faster, they have less time to react, and if they have a close encounter with a tree, they auger in harder.
I'll also throw up a strawman that I'm sure will be controversial. How many skiers and boarders wear helmets, at least in part, because they provide protection in the event of hitting a tree? Of those who do, how many ski faster around trees because of an increased sense of security, due to the helmet?
As Amar said, "Just as with avalanches, the MOST important thing is to avoid creating an accident and becoming a victim at all -- rescue skills and techniques should be secondary. Skiing in a manner to avoid tree well accidents should be a priority." At the risk of sounding like Your Mother, I think the best thing any of us can do to avoid a tree well accident is to slow down.

Possibly reliable stats: www.nsaa.org/nsaa/press/facts-ski-snbd-safety.asp
It's impossible to iron out all the risk from mountain sports. I'd guess that most people who die at ski resorts do so on the groomers.

The intro and wrap-up, with all the talk about intending to produce a video on avalanche training, are just entirely irrelevant add-ons, although that's obviously pretty, well, obvious.
(BTW, the details are from a NE regional discussion group plus some emails with an acquaintance of some of the participants.)

as I made a turn over the convex the ground gave out under me and I dropped into a hole. Lost one ski, the other stuck in deep... I was more upright but on my side. I wasn't totally buried or deep... but I recall more depth below me as I tried to free myself and at one point snow falling in gave me a scare, I stopped making sudden movements to free myself with brute force. Behind me I could feel a large fallen log that gave me support. After about 10 minutes I got out fine and was able to find my other ski but have never forgot this. My imagination it was a hole created by a blowdown pile, terrain, vegetation... don't really know. Overall, I think this is an anomaly type of "tree well" but I thought I'd share.
I can't say what the best practices are, the most I have heard discussed is stick with a partner and ski in control. I have one friend that actually makes 'whoop whoop whooping' sounds (ye-haws, wo-hooos, whatever) on the way down skiing trees. Being the last person down is tougher to spot, especially in low visibility conditions. I know in most of the larger groups I've toured with radios are always in use keeping check on each other BVR and the 'sweeper' being radioed that all are down before dropping in. In hindsight the sweeper should probably be a two person team. I've become a big believer in touring with radios in any group large enough to get split up with no less than one radio for any 2 person team. But whats ideal and what others bring is not always the same even when you request it in advance.

Monday morning quarterback response is:
-Communicate to the victim, assess airway (determines aggressiveness/injury considerations)
-Communicate the problem to partners, deploy shovels
-make sure rescuers don't knock more snow on victim
-have a plan to dig and recover
-prepare for rewarming victim
-maintain airway as highest priority and reassess victim when extricated
-learn lesson, and ski away
And yeah, prevention is preferred.

Since he was the author of the data in Tree Well & Deep Snow Safety , I queried Paul Baugher on the topic to find out if he any more info on the topic since the publishing of the piece.
Here is reply:
“Ron,
Thanks for the interest. Here is my paper from 2008 that discusses some of the problems with rescue- see the results of the field experiment with live subjects. Also I updated the research this summer. We have designed a new brochure that is now available through the NSAA and we are in the midst of the redoing the treewelldeepsnowsafety.com website. It will contain more information on rescue including the importance of tunneling for the airway. By the way we are changing the label to Snow Immersion Suffocation.
Though this is primarily a ski area problem (3% of U.S. cases have occurred in the backcountry) your folks are alpine skiers as well. Please post this on TAY.
Best Regards,
Paul Baugher
Risk Manager, Boyne Western Operations/ Director, Crystal Mountain Ski Patrol
Owner, International Mountain Guides”

This may be the wrong mindset.
Instead, maybe we should approach deep snow skiing in trees the same way we approach unroped skiing on a crevassed glacier. Unroped skiing on glaciers is considered acceptable if the crevasses are visible and the party skis conservatively. All skiers slow down, ski well below their abilities, and give crevasses a wide berth. The mindset is that even if you carry a rope and wear harnesses, falling into a crevasse is unacceptable and a rope and other gear is likely to be good only for a body recovery.
Maybe we should think about tree-wells the same way. Tree-wells are deadly and if the last person in a group goes in, his or her friends may be unable to find the victim in time to save them. Thinking like a glacier skier, every member of a tree skiing party should give tree-wells the same level of respect that you'd give an open crevasse. Slow down, stay completely under control, and give each tree a wide berth.
Except for rare instances (like the one described by Koda) the location of a tree-well is obvious, because there's a tree in it. If you take the mindset that falling into a tree-well is never acceptable, it seems to me that this might lead to the kind of skiing that would reduce the danger to a minimal level.

This system is not perfect. Sometimes the skier behind takes a slightly different route and you find yourself separated or out of order. Calling back and forth helps. Still, it works better than the usual advice to watch the skier ahead, which also works until that skier disappears from sight.
The advice to keep your potential rescuer in sight is not intended to imply that you may ski recklessly and expect to be rescued. I am equally afraid of tree wells and avalanche. I am also an avid practitioner of the face plant, unintentional of course. From a post above, it sounds like the skier in the tree well may have been avoiding close encounters with trees but tripped on a hidden object and was launched into the tree well. I can relate to that.

That issue aside, the tree well is a very real danger to all skiers, unless you never (ever) fall. Did you notice the size of the tree? It was not a majestic hemlock as might be imagined, but a pathetically small (almost) seedling . One should ask themselves "How many times have I skied by a tree of that size?". Maybe after seeing the video we all will begin noticing such traps and appreciate the danger. I daresay the actual skier involved had no chance to escape on his own. If your skis stay attached, you are sunk.
I had the misfortune to fall into a well not unlike the one pictured. I was in a group of 6 or 8 and was the last skier down a modest glade, when I took a header and landed upside-down with a mouthful of snow. My immediate panic was that I was going to black out and suffocate, but I was able to calm down and get my breathing under control. (I happened to be wearing a heart-rate monitor and it pegged at 235). I tried yelling for help but the sound only travels a few feet when buried in soft snow. Fortunately, I had broken one of my poles (a precious Choiunard classic) and thus could move that arm around to release my tele-bindings. It might have been possible to extract my wrists from the pole straps, but I did not have to go that route. I had only recently decided to ski in the backcountry without tether cables on my skis, so that facilitated my self extraction. It is possible that I would not have been able to get out of the hole if I had those safety straps clipped.
Which brings me to the issue of group dynamics. I was only about 100 vertical feet above the spot where my group was going to stop and skin up for the next run. It is very easy to convince one's self that the missing skier ended up taking a slightly different line and would emerge onto the uptrack at a different place. I could very easily have been in the well for several hours (it was getting late in the afternoon) before they all figured out that I was MIA. The snow was pretty tracked up, making it not obvious where I had gone down. I was pretty shaken, but what I least appreciated was the indifference that the group showed when I told my story. They are all stronger skiers than I, but do not share my cautious nature. I have not ventured out with them since that day.
The lessons I took away:
1. Ski with people who share your group ethic,
2. If you ski alone, don't venture where others will not easily find you,
3. Think carefully about straps on poles and skis.
4. Do not assume that a small tree poses no danger. Think about how many similar trees you encounter.

The piece done by Paul Baugher that glenn_b linked to (www.treewelldeepsnowsafety.com) has some good info re: avoidance. I especially liked the reminder to “leap frog” ski deep snow so that watching ski partner is always above and in sight of the skiing partner. I am going to try and do a better doing this when conditions merit. But there is really very little (just a bit under “4. FIGHT TO SURVIVE” on page 5) to help the rescuer and/or the victim do a more effective rescue. Paul is apparently in the midst of redoing that info so it might be worth keeping an eye on it.
There has been some other pretty good suggestions here regarding skiing policies and procedures to mitigate the likelihood of falling in.
But again, there doesn’t seem too much, to help us become better tree well rescuers.
And it does not sound like I was the only one that felt that rescue effected in the video could have been accomplished much more effectively had the folks practiced a rescue drill a few times.
I think developing some "strategic shoveling" guidelines for tree wells would be very valuable to the outdoor community.
I agree.
Perhaps we should practice getting out of tree wells more often...
I am planning on doing exactly that.
Interestingly, I have some related experience that may be helpful in this endeavor.
I actually have a fair amount of time rooting around in tree wells (head up, of course). This was in junction with teaching ski mountaineering students how to fashion what I call the “30 second” snow shelter.
The technique his use involves skiing as close as I dare to the subject tree (usually skinning) and then release my bindings while staying upright. Then using the poles to help stay upright I walk through the branches directly towards the trunk of the tree, usually dropping the poles as soon as I drop into the branches, where the poles just get in the way. With a typical PNW snowpack, to a casual observer one will appear to disappear almost immediately. Once bottomed out it is a simple matter to just root around laterally back in forth to make room for the intended occupants.
So this experience leads me to believe that, at least some times, and even maybe the most of the time, depending on the particular tree well, branch cover, etc, one should be able to get an airway to the victim much sooner that it appeared to happen in the video.
So for practice, I can see us having one person acting as the “victim” and walking into the tree well, in this case head side up, as I described above. In this case the victim’s feet or lower legs would serve as the victim’s “head” for the practice, for obvious reasons.
A “rescuer” would then enter the tree well two or three feet away from the victim’s hole so avoid knocking snow into the victim’s entry hole. Once bottomed out on the rescue hole, the rescuer packs out the snow enough to get some working room and then immediately begins tunneling for the victim’s “head” (in this case, feet) to establish and maintain an airway and communication to the victim.
Once accomplished, then the victim can be extracted with lateral strategic shoveling as needed while care is made not to disturb the airway.
If enough rescuers are available (as there were in the video) two rescuers could drop into the tree well, one either side of the victim, to help improving the chances of getting a new airway to the victim sooner, and maintaining same, while the others immediately start strategic shoveling.
Summarily, unless I am mistaken, I believe that, if it all possible, by approaching the victim from within the tree well rather than from the snow surface above, we will have a higher likelihood of more quickly and more reliably getting fresh air to the victim, thus simplifying the rescue.

Jeff, if there's a body of commentary on this video indicating what was done right, what was done wrong, and what would have made a better rescue....can we hear more about it? Read it for ourselves somewhere? I'm finding it frustrating to hear that the video "was circulated around the Canadian ski guide community last year" for long enough to achieve consensus in the absence of any further details.
Mark,
Unfortunately these conversations took place on a professional forum that isn't open to the public. The people that set it up have limited the access to certified guides so the guides can speak/write freely. It is a very helpful exchange but if it was open to the public many of the comments would be censored for fear of them being taken out of context or misunderstood.
In my opinion, the best way to avoid a serious tree well incident (while still having fun skiing in the trees on a deep day) is to do a good job buddy skiing. If you have a good ability match with your ski partner it's pretty easy to keep each other in sight or in voice contact. My favorite "trick" is to have the person in the back continually making noise, so the person in the front knows they are still there. That way the person in front can focus on the skiing and stop looking over their shoulder.
Then if you do have an incident you have someone relatively close by to help. One of the hardest parts of a tree well incident is actually finding the patient. If you aren't close when they disappear it ends up being a huge transceiver search without the benefit of an avalanche path to limit the search area.
