Grand Teton National Park rangers on Saturday recovered the body of
24-year-old ski instructor Allen Wagner from an avalanche site on the back
side of Apres Vous Mountain.
Wagner died in the avalanche Friday after he apparently set it off at about
4:15 p.m. The slide carried him over a 40 foot cliff and some 500 feet
down the slope where he was buried three feet deep, park officials said.
He is the fifth avalanche victim in Teton County this season, the 26th in
North America. Bridger-Teton National Forest avalanche forecasters have
warned all winter of suspect layers in the snowpack and have logged dozens
of observations of skier-released avalanches in the mountains around
Wagner, originally from Boulder, Colo, and friends Zach Giffen, Jeff Giffin
and Torrey Rodgers, all in their early 20s, left the Jackson Hole Mountain
Resort from the Apres Vous lift at 4 p.m. to start their excursion. A
preliminary report by the BTNF forecast center noted that there is no
regular gate in the ski area boundary where the four left the resort.
The group intended to ski a steep 200-foot chute near Caledonia Couloir.
Wagner approached the chute a different way than his friends and apparently
provoked the avalanche.
In its preliminary report to the Westwide Avalanche Network, the local
avalanche center said a small slide provoked a deeper fracture - about two
feet deep - that carried Wagner down the side of the canyon. The incident
occurred on a north-facing slope at about 8,000 feet on a day when the
danger was rated at "considerable." "Considerable" danger indicates a
condition when human-triggered avalanches are probable. There had been 3
inches of new snow in the previous 24 hours, 15 inches in the previous
The slide stopped at Granite Creek, close to Jeff Giffin who had skied down
first. He turned his avalanche transciever to "search" and quickly got a
strong signal from Wagner's transciever, park officials said.
Zach Giffin arrived at the scene and hit Wagner with his first probe into
the snow. Friends freed Wagner's face of snow in five minutes, but it took
another 15 to free his body to the point they could begin rescue breathing,
park officials said. One of the party skied out to notify the ski patrol,
who learned of the incident at 5 p.m.
The park launched a helicopter and the Mountain Resort dispatched four ski
patrollers to the scene. The helicopter had to retreat in the face of
darkness, but the ski patrol reached the scene at 6:30 p.m. Patrollers
continued resuscitation efforts with an electronic defibrillator and
oxygen, without success.
The skiers left the canyon that evening and Wagner's body was flown out
The park used the incident to remind backcountry users of the grim
statistics regarding avalanche survival and death. Among avalanche victims
who are buried less than a meter deep and uncovered within 15 minutes, 20
percent still die.
"This tragedy reinforces repeated safety messages, which have been
emphasized throughtout this winter," the park said. "Avalanche danger
remains 'considerable' to 'high.' Backcountry skiers need to know the
terrain they are traveling in and be prepared for all types of winter
emergencies, including the possibility of a life-threatening accident.
Further, backcountry skiers need to understand there is no guarantee of

A 22 year male skier became the fifth local avalanche fatality of the season yesterday, February 23, 2001. The victim is
believed to have triggered a small slab which swept him over some cliffs. This event then triggered a slab on the snow
apron beneath the cliff believed to be two feet in depth. The victim was wearing a transciever and is reported to have been
located by his partners within five minutes at a depth of three feet in the toe of the debris. Attempts at resuscitation were
This incident occured in a steep cliffy area on a northerly aspect in Granite Canyon in Grand Teton National Park in Teton
County, Wyoming. The victim and his party accessed this area from the Jackson Hole Mountain Resort, however there is
not a backcountry access gate at this location. The starting zone of this incident is suspected to be at an elevation of 8,000
feet. This infromation is provided by the Bridger Teton National Forest Avalanche Center and is preliminary.
