Spokane’s Dawes Eddy reached the summit of Mount Everest Tuesday, becoming the oldest American to climb to the top of the world’s highest mountain.
Eddy, 66, has spent the past two months traveling and climbing the 29,035-foot Himalayan peak in Nepal. He climbed as a part of the International Mountain Guides team.
Eddy left his tent at about 10 p.m. Nepal time with Sherpa Mingma Chhiring and other climbers, and reached the summit about nine hours later.
“I will be really relieved once he gets back down…I’m anxious for him to get all the way back to base camp and call me and tell me he’s fine,” said his wife, Mary Kay Eddy.
Mary Kay Eddy says her husband has called from a satellite phone periodically throughout the climb. He’s been gone since March 22.
“He told me that he felt great and everything was going well, that he enjoyed the people he was with and hasn’t had to take an aspirin,” Mary Kay Eddy said. “He couldn’t get over how beautiful it was. He stands in awe of the mountains.”
Eddy has been the focus of a high-altitude health research project featured in The Spokesman-Review. A group of scientists, physicians, psychologists and athletic consultants are using Eddy as a research subject to test their theories on aging and altitude. He spent months undergoing a battery of tests to establish his baseline health and fitness before departing for Nepal.
“He’s got some of the highest data I’ve seen, in terms of fitness for someone his age,” said Don Winant, a Washington State University professor and research coordinator for the climb.
Eddy, who has climbed 14,410-foot Mt. Rainer 37 times, is considered an elite athlete by research standards. For example, his VO2 level — or the body’s ability to deliver oxygen into the bloodstream — is 137 percent of normal, Winant said.
“All his physiology and history of climbing skewed the probability in his favor of making the summit if he didn’t get sick, or the weather didn’t turn sour,” Winant said. “He’s a specimen.”
After his climb, the team of researchers, numbering 15 or more, will conduct another series of tests to measure Eddy’s physiological changes, and how the high-altitude and depleted oxygen levels affected the brain and central nervous system. The research will be published in a medical journal, and could be used to benefit other climbers.
“The whole paradigm of how we view aging is changing in this country,” he said. “Twenty years ago if you were 66 years old and trying to summit Everest, everybody, including doctors, would think you were crazy.”
