ANCHORAGE, Alaska (AP) _ One climber died and four others were airlifted off Mount McKinley after severe weather assaulted North America's tallest peak, National Park Service officials said.

The group of seven Taiwanese climbers were forced to make their camp at 19,400 feet when high winds and white-out conditions struck the 20,320-foot mountain Tuesday.

The next day, four of the climbers climbed 2,000 feet down and were able to alert authorities, and two of them, Jung Chung Chang and Hsieh Tzu Ching, were airlifted Thursday to a hospital to be treated for frostbite.

Chiu Jui-Lin, 29, had died by the time rescuers reached the three left behind at the 19,400-foot level. Dois Min Lin, 32, and Min Chung Wu, 28, were helped down to the 17,200-foot camp and then airlifted to a hospital.

Park officials did not immediately know the whereabouts of the two other climbers at the lower camp. They also said one climber had been released from a hospital.

The team was trying to climb McKinley to prepare for a 1996 expedition to Mount Everest.

The accident brings to six the number of climbers who have died this season on McKinley.
