One of two climbers stranded on Mount Rainier died Thursday before the other was plucked from the mountain by a helicopter, officials said.

The climber, Jon Cahill, had died by the time a party of five rangers reached the two, who were stranded at 11,300 feet, said Mount Rainier National Park spokesman Barry Fraissinet.

His partner, Mark H. Anderson, had a wrist injury and was evacuated by an Oregon National Guard chopper, Guard spokeswoman Kay Fristad said. He was flown to Harborview Medical Center in Seattle, where he was in satisfactory condition, hospital spokeswoman Susan Gregg-Hanson said.

Both climbers were firefighters and trained as emergency medical technicians, Fraissinet said.

Cahill fell early Thursday as the pair tried to ascend Liberty Ridge, one of the most difficult routes up the 14,410-foot peak, Fraissinet said. The accident happened about 1,000 feet below where a climber was fatally injured in a fall last month.

The Guard helicopter dropped a party of five climbing rangers 500 feet below the injured climbers. The rangers climbed up to assist with the evacuation by helicopter but found one of the climbers dead.

The Black Hawk held steady as a medic was lowered by cable. The rangers hitched the injured climber to the medic, and the pair was pulled into the helicopter.
