SEATTLE - Six climbers on Mount Rainier likely perished in a fall after helicopters detected pings from avalanche beacons and spotted climbing gear thousands of feet below the group's last known location, national park officials said Saturday.
Searchers believe the group fell 3,300 feet from their last known whereabouts of 12,800 feet on Wednesday, park spokeswoman Patricia Wold said in a statement. The helicopter crew spotted camping and climbing gear in the avalanche-prone area, park Ranger Fawn Bauer told The Associated Press.
"There's not a viable chance of survival," Bauer said.
Air and ground searches were suspended late Saturday afternoon. The danger of falling rock and ice in the area where searchers picked up the pings prevents a ground recovery effort, Wold said.
"It would expose our rangers to pretty extreme conditions," Bauer said. "And, in all honesty, we may never be able to get on the ground there."
The loss of life would be among the deadliest climbing accidents ever on the peak in the Cascade mountain range. In 1981, 11 people were killed during a guided climb when they were struck by a massive ice fall on the Ingraham Glacier.
Aircraft will survey the area periodically in the coming weeks and months, Wold said, but the possibility of recovering the six is uncertain.
The missing group includes four clients of Seattle-based Alpine Ascents International and two guides. They were due to return from the mountain on Friday. When they did not return, the climbing company notified park officials, Bauer said.
Officials have yet to finish family notifications, so the names of the climbers had not been released Saturday night.
"The climbing community is a small one and a close one and a loss of this magnitude touches many," Superintendent Randy King said in the statement.
Mount Rainier, southeast of Seattle, stands at 14,410 feet and attracts thousands of climbers trying to reach its summit every year. It is popular with climbers of all abilities, from novices who take guided climbs to experienced alpinists who use the glacier-laden peak to train for attempted ascents on taller mountains in the Himalayas and other mountain ranges.
