Well, having just taken the Avy 1 course this past weekend, I found many of the facts of the story below pretty telling.

I first saw the story on the Weather Channel last night. They interviewed the survivor's brother, who mentioned that they had witnessed slides "below them" earlier, but they thought they were in an okay spot. The article below notes that Avy Danger was HIGH! And nobody had beacons. I just couldn't help but thinking of this in terms of the Avy 1 training this past weekend. Anyway, you'll see from the article that the survivor was EXTREMELY lucky, having been buried 6 feet deep, without a beacon, found by probes only! (for the avy-trained, you no doubt know that the chances of survival if you're more than a meter deep are very slim; and a probe-only search narrows the chances even more considerably). During the interview on TWC, the brother stated that he couldn't believe how heavy the snow was; that he could only shovel for 1-2 minutes before his arm felt like it would fall off. He said that it not for the fact that they had multiple people to take turns digging, it would have been all over for his brother.

Here's the story from the Jackson Hole Daily News:

Slide kills snowmobiler in Salt River Range

December 19, 2006

A snowmobiler died in an avalanche Saturday in Lincoln County in what might be one of the first avalanche deaths in the U.S. this season.

The Bridger-Teton National Forest Avalanche Center reported a large slide buried two snowmobilers high-marking on an east aspect at 9,500 feet in the Murphy Creek area of the Salt River Range. Neither person was wearing an avalanche transceiver, the avalanche center reported, but witnesses were able to probe for and resuscitate one victim who was buried 6 feet deep.

The person who died was buried in 8 to 10 feet of snow.

The victim’s name and other details were not immediately available, and attempts to contact Lincoln County officials were unsuccessful Sunday.

The avalanche center had listed the hazard for the area on Saturday as high, meaning mostly unstable snow exists on a variety of aspects and slope angles, natural avalanches are likely, and travel in avalanche terrain is not recommended.

According to today’s western Wyoming advisory, the general hazard will be considerable. The avalanche center reports dangerous slabs exist up to 5 feet in depth that continue to be very susceptible to human triggers on a variety of aspects above 7,500 feet.

“Don’t be lured by the tracks of individuals willing to accept a high level of risk,” the advisory says. “Current conditions require that each party make their own hazard evaluations and make conservative decisions based on those findings.”

edited to add: for more avy info on that area, check www.jhavalanche.org , a great site with a lot of fantastic information. you can check the archived advisories for before and since this accident (avy danger was and remains "considerable" above 9,000 feet).

I can only assume that terrain selection is harder on a snowmobile due to thte shear amount of terrain you can cover.

When hiking to a spot you usually stop to rest and have time to look around and evaluate. Going 50mph on a sled into new terrain you might not even think.

except that the posted Avy Danger, available at the touch of a button, or a phone call, was HIGH or CONSIDERABLE everywhere in that region!

Also, doesn't appear they were "going around" anywhere - they were hanging out in that spot taking turns high-marking.

Very sad. This would seem to fall into the "80 percent preventable" catagory. :(

Yeah you aren't going to notice Whumping or see the intracacies when speeding past at 50mph. This is where proper planning will save your life.

Luckily there weren't 2 fatalities in this case.

Was trying to find out where this happened - to take a look at the terrain.

I found these co-ords on a topomap site:

43.0625°N, 110.8320°W

You can drop that into google earth and it brings you to a spot just below Murphy Lakes which sounds like the location described in the article. There's a couple peaks to the south of the above co-ord that almost reach 9,500.

wow. the survivor is incredibly lucky. Found by probes, and then succesful CPR? thats incredibly rare.

Yeah - I recall hearing of several avys triggered by 'bilers engaging in this activity. I think I even saw a video of a fatal avy triggered by a high-marker in CO a season or two back. It's definitely sad, but seems these guys were really clueless in very dangerous conditions. Like others have said, it's shocking that there weren't two fatalities. That's one lucky dope who got found by probing without a beacon.

I'm not surprised to hear of this incident, though. My friend who works at JHMR called on his way to work Monday a.m. and told me that everything had released over the weekend. Apparently they had some rain early last week, then a huge temperature drop, creation of a thick, nasty layer of surface hoar followed by a big dump of low density fluff. He said there were fracture lines everywhere that I'm sure he'll be sending photos of soon. I told him to be careful and he said the only place he'd consider riding out of bounds was some mellow, treed terrain at Teton Pass.

Phil's a smart, experienced guy (he rode with both Tom Turiano and Stephan Koch last year) so I'm sure he'll be taking appropriate precautions until the snowpack stabilizes. He's also got an extra bedroom in his place that I hope to be putting to good use after I pick up my splitty this weekend :D and take a week or two off in January between jobs, which'll be kinda cool.

He sent me a photo of the inversion yesterday that shows the clouds in the valley and bluebird above, but I'm too stoopit to figure out how to post it.

pulver, if you happen to be out there between Jan. 15-21, let me know. I'll be out there with my bro and a couple friends. check out the J-Hole avy link I sent, there's good stuff on there. I'll be watching it carefully, as I hope to do a little off-piste while I'm there.

I will definitely let you know if and when I'll be there as soon as I know myself, boardman. I could be there right around the same time as you. Thanks for the link - I'll be watching it too.
