Please keep your wits about you til everything stabilizes.

They've consistently had similar amounts in the tetons, with some pretty scary releases in the days following. Some injuries, but no fatalities to date.

Avalanche injures man

By Cara Froedge
January 3, 2008

Five rescue workers spent Tuesday night in the backcountry tending to a snowboarder injured after sliding about 1,300 vertical feet in an avalanche, the last accident in a day that brought several skier-triggered slides.

Doug Meyer, Teton County Search and Rescue director, said the snowboarder triggered the slide about 4 p.m. on Tuesday in Unskiabowl near Teton Pass. The snowboarder and three others were traversing north on the ridge of Mount Glory when he decided to check out Unskiabowl, Meyer said.

As he was peering into the bowl, the cornice he was standing on broke and pulled him over the edge.

That fall triggered a 75-foot-wide slide that swept the snowboarder off a 50-foot cliff. That started a larger avalanche about 6 to 8 feet deep and 300 feet wide, Meyer said.

The snowboarder then slid another 1,200 feet down to the bottom of the bowl, he said. A sheriff’s deputy’s report said the snowboarder was not buried but was injured and couldn’t move his legs.

Capt. Jim Whalen of the Teton County Sheriff’s Office said Wednesday the details of the accident were still sketchy and the deputy who wrote the report was not in the office.

According to the preliminary information, the accident wasn’t reported until 6 p.m. by a member of the party who had met the other three men only that day.

That fourth person, visiting from Minnesota, knew only the first names of the others involved: Toby, Matt and Jeremiah. He hiked out to report the accident while the other two stayed behind with the injured snowboarder, reportedly named Toby.

Because it was dark, the snowpack was unstable and subzero temperatures were possible, rescue workers decided to send a team to bring extra equipment and clothing and stay overnight.

Meyer said five Search and Rescue workers, including a doctor, started toward the three men around 8:45 p.m. and reached them about an hour later.

Once rescuers arrived, they found that the snowboarder had injured his pelvis and a companion was diabetic and had no insulin.

“We ended up having two patients,” Meyer said.

The two men were stabilized and flown from the bottom of the bowl to St. John’s Medical Center just after 7:30 a.m. on Wednesday.

On Tuesday there were at least three other skier-caused avalanches following a major winter storm.

One slide near Jensen Canyon, on a peak known as the Pyramid, was likely triggered by two skiers climbing a ridge near the slope.

After that slide, Search and Rescue conducted a helicopter search of the debris in case others might have been caught in the avalanche. Searchers employed an avalanche transceiver dangling beneath the airship to scan the slope for any transmissions from a beacon a buried skier might have been carrying.

Then, two skiers traversing a slope together south of Jackson Hole Mountain Resort triggered a 4-foot-deep fracture at 10,500 feet. They were carried by but survived the slide.

Three skiers climbing a southeast slope at approximately 10,300 feet in Grand Teton National Park also were caught but not injured by a slide visible from Jackson.

Hope the snow keeps coming here and there and that folks use their knowledge, training, experience and common sense. This may need some emphasis on the rockpile in the next 5-8 days or so, what with the buttloads of snow, a warm up, folks thinkin spring may have sprung, with unrealistic perceptions of stability. If you see some gapers doing stoopit shyte, maybe give em a bit o friendly advice . . .

Can't help but wondering what the Avy ratings were at the time. I suspect they were Considerable at least, if not High. Just not worth being in avy terrain in those conditions, unless you have a real affinity for Russian Roulette.

edited to add: it appears that avy rating was Considerable for above 9,000 feet, and moderate from 7,500 - 9,000 for that time frame:

Correct. And with the combination of Mt. Glory being the highest point in the region at around 10K, the many protected aspects, ease of accessability, and throngs going up there leading to the misconception that it's stable, it's no wonder people take a shot at stuff like these runs. Similarly, I wouldn't be surprised to see peeps hitting some dangerous aspects of the rockpile if conditions cooperate this weekend.

I like to think I'd be in the trees on a day like this, but honestly, with my buds out there (who are MUCH more experienced than I am) going out in similar conditions and ratings on Christmas Day (when considerable rating went down to 7,500') and shralping stuff like this (Glory Bowl - next to unskiabowl)

I hope, but don't know that I'd have the sense to "just say no go".

Just my $0.02, FWIW.

The snowfields have formed by Nelson Crag...the even look good! Fairly modest angles and wind loading is often less of a problem there due to the depth of Huntington Ravine.

Speaking of which...I'd love to see a photo of the Huntington Northside gullies....they should be full of snow just about now :D Might even be skiable....that doesn't happen often.

Hard to say from that photo angle, but that slope angle looks pretty mild, maybe around 30 degrees? Just outside of avy prone, IIRC. But like I said, the photo could be deceiving.

Ha! I said to someone on the chairlift at Wildcat yesterday, "it's pretty rare, but damn if Huntington doesn't look like it's got enough snow to be skiable"! :D

West side coverage, at least looking on the webcam, looks pretty damn significant too!

Yeah, the photo is deceiving - pretty much ideal avy terrain - 35-40 degrees. It's actually so prone that it's a study plot with remote sensors installed for an infrasound avalanche study: http://www.avalanche.org/~issw2004/issw_previous/2004/proceedings/pdffiles/papers/114.pdf

My buddy actually triggered a decent release in the gut skiing by moonlight at the end of last season. I am pretty sketched out by that story and really hope not to be involved in anything like that.

Wow that boarder is super lucky to survive, talk about a chain reaction.

It amazes me that people disregard AVI ratings and warnings from qualified personnel.

Last season at Tux on a Saturday (i think) the conditions were Considerable to High, and rangers were advising people to not venture into the bowl or onto hillmans for obvious reasons.

We witnessed a slide on Hillman's which took out a few people; thankfully no fatalities, but some broken ribs. (saw instructor Steve helping out)

Follow-up to pulver's original post. The JH Avalanche center has photos of two of the slides mentioned in the article. Check out the Snowpack Summary for Dec 28 - Jan 3 here:

oh yeah, and they just got another 26" in the last three days, with another foot expected on Wednesday. Glad this is the first year in five years that I won't be going to Jackson Hole.

Somebody please kill me now . . .

Somebody please kill me now . . .Dude, put down that club and go check out the East Coast Stoke thread at T-Tips....we have been skiing powder for 40 days right here on the Ice Coast!

A few of those fracking Westies have been flying in to schralp our goodies...but now they have their own....Big Time in the Sierra!

A follow-up article to pulver's original post. A good read; lots of lessons to be learned.
