In the ascent, Arnot also solidified her record for most summits by a foreign woman, which she previously held, and now sits at six total ascents.

It’s an immense accomplishment, but there is an asterisk: Her ascent without oxygen is the first by an American with the footnote that it follows that of Francys Distefano-Arsentiev, an American woman who reached the summit without oxygen in 1998 but died during the descent.

“I never anticipated that I would be lucky enough to summit once, let alone six times,” Arnot said. “Climbing Everest without supplemental oxygen has been a goal of mine for a long time.”

She continued, “When you succeed at reaching your goal, it makes you reflect on the hard days, the work, and lessons I’ve learned along the way. I’m incredibly fortunate to have this experience.”

Arnot, 32, a guide and Eddie Bauer athlete, summited via the north side from China. It was her first ascent up that route, with her previous five summits attained via the South Col route on the Nepal side of the mountain.

Ascending to the 29,029-foot summit of Everest requires supplemental oxygen for the vast majority of climbers. Of the more than 4,000 climbers who have summited Everest, less than 200 have done so without breathing bottled oxygen.

The first woman to climb Everest without supplemental oxygen was Lydia Bradley of New Zealand, who summited on Oct. 14, 1988.

More than 400 people are attempting to climb Everest this year. The news of Arnot’s summit comes as a bright spot among dark news from the world’s tallest mountain this month.

Four climbers died during the past week: crew member Phurba Sherpa died Thursday after falling; Eric Arnold died Friday; Maria Strydom died Saturday; and Subhash Paul died on Sunday.

A professional mountain guide since 2004, Arnot has guided on three continents, summited Mt. Rainier, Washington’s highest peak, 104 times, and will be attempting to climb the highest peak in all 50 states in 50 days this summer.

She will embark on the 50 Peaks challenge from approximately June 30 to August 20, 2016, with Maddie Miller.
