Backcountry Skier Dies In Avalanche On South Teton
A backcountry skier triggered an avalanche on the South Teton that swept him to his death on the morning of Sunday, February 21st. Wray Landon, 30, of Driggs, Idaho, skied with two companions to the summit of the South Teton via Garnet Canyon and the Northwest Couloir early Sunday morning. They were descending the southeast face of the peak when Landon set off a two-foot crown avalanche approximately 300 feet below the 12,514-foot summit. The avalanche carried Landon over 2,000 vertical feet of slope and cliff bands before he came to a rest about a thousand feet above Lake Taminah in upper Avalanche Canyon; the avalanche debris continued about 800 feet further before stopping. Landon and his companions were experienced with backcountry travel in the Teton Range and prepared with the appropriate equipment for a mountain excursion. Landon’s ski companions, Nathan Brown and Brady Johnston, made a 911 call to report the incident at 11:35 a.m., and the Teton Interagency Dispatch Center received notice from the Teton County Sheriff’s Office shortly after. Park rangers immediately summoned the Teton County Search and Rescue contract helicopter to assist with the rescue operation. An aerial reconnaissance flight was conducted at 1:15 p.m. during which rangers were able to determine that Landon was deceased, although not buried by the avalanche debris. In order to reach Landon, who was lying in an exposed avalanche-prone area, four rangers were flown via helicopter to a landing zone near Snowdrift Lake (elevation 10,006 feet) from which a recovery operation could be staged. Three Teton County Search and Rescue personnel were flown into the location, and they conducted aerial avalanche control using explosives to stabilize slopes above the route rangers intended to ski in order to reach Landon. After the avalanche control work was completed, four rangers traversed a steep slope below an area of cliff bands and couloirs. While two rangers acted as safety spotters, watching for additional avalanche activity, two rangers prepared Landon for aerial evacuation. Landon was airlifted by a long-line to the valley floor at 4:45 p.m. Landon’s two companions skied out of the backcountry on their own and the rescue personnel were evacuated by air, completing their operation at 5:30 p.m. The avalanche condition rating that day was listed as “moderate” for mid level and high elevations below 10,500 feet. The Bridger-Teton National Forest Avalanche Center does not forecast areas above 10,500 feet, and park rangers remind skiers and climbers that conditions on the higher peaks can be vastly different above the Bridger-Teton forecast zone. A moderate rating means that areas of unstable snow exist, and human triggered avalanches are possible. The general avalanche advisory warns that pockets of dense surface slab up to 30 inches deep rest upon buried surface hoar and sun crusts at the mid and upper elevations, and the possibility persists for backcountry travelers to trigger these slabs in steep, avalanche-prone terrain.

Slide kills skier in park

February 22, 2010
A skier died Sunday when an avalanche reportedly swept him over a 1,500-foot cliff on the South Teton in Grand Teton National Park.
Wray Landon, 30, of Driggs, Idaho, was skiing with two others, who were above him when the avalanche broke before 11:30 a.m. on the south face of the 12,514-foot peak, park spokeswoman Jackie Skaggs said.
The other skiers, Brady Johnston, of Driggs, and Nathan Brown, whose hometown was unavailable Sunday, were not caught in the avalanche and were eventually able to ski out.
Skaggs said the three had summitted the peak via Garnet Canyon and the Northwest Couloir and had skied down about 300 to 400 vertical feet when the avalanche struck and carried Landon about 2,000 vertical feet.
Brown used a cell phone to call 911 about 11:30 a.m. and tell dispatchers Landon was caught in an avalanche and he thought he could see him at the bottom of a 1,500-foot cliff, Skaggs said. Park rangers were then notified. Rangers used the Teton County Search and Rescue helicopter to fly to the area and could see the body below the cliff, Skaggs said.
Seven rangers and three Search and Rescue volunteers then began an effort to recover the body, she said.
Skaggs said the slide had a crown of about 2 feet and that the party appeared to be equipped for travel in avalanche terrain.
Landon’s Facebook page said he was the resource specialist for the Teton Regional Land Trust. The land trust’s Web site said Landon attended the University of Montana, where he received his Bachelor of Arts in liberal studies in 2001, had formerly been a ski coach at Grand Targhee Resort and had lived in Teton Valley for more than three years.
In his blog, TetonAT.com, occasional ski partner Steve Romeo said Landon had recently moved to Jackson.
The Bridger-Teton National Forest Avalanche Center rated the avalanche danger as “moderate” at high elevations for Sunday, though the center does not include elevations higher than 10,500 feet in its forecasts.
“At the mid and upper elevations, pockets of dense surface slabs up to 30 inches deep rest upon buried surface hoar and sun crusts,” the center’s report said Sunday morning. “The possibility persists for backcountry travelers to trigger these slabs in steep, avalanche-prone terrain.”
The death is the second avalanche fatality in the Tetons this winter.
