Norman Vaughn climbed Mt Vaughn 3 days before his 89th birthday

Days before his 89th birthday he and his wife, Carolyn Muegge-Vaughan, returned to Antarctica and climbed to the summit of 10,320-foot Mount Vaughan, the mountain Byrd named in his honor.

"It was the climax of our dream," he told The Associated Press in a 2005 interview at his Anchorage home. "We had to risk failure to get there. We dared to fail."

Vaughan continued to seek adventure his entire life. His exploits included finishing the 1,100 mile-Iditarod Trail Sled Dog Race six times after age 70. At age 96, he carried the Olympic torch in Juneau, passing the flame from a wheelchair, 70 years after he competed in the Olympics as a sled dog racer.
