Ecuadorian Carla Perez successfully reached the top of Mr. Everest on Monday morning. She made history in the ascent of the 29,035-foot mountain by doing it without supplemental oxygen.
Perez accomplished her feat following the deaths of four climbers within five days on the world’s tallest mountain. A Nepalese Sherpa died Thursday as he attempted to repair a trail near the summit while climbers from Australia, the Netherlands, and India died of exposure and altitude sickness over the weekend.
Perez was in a group of four Argentinians, one Mexican, and another Ecuadorian climber, Iván Vallejo, who reached the summit.
Vallejo tweeted the news of the successful climb. “Carlita is great!”, he wrote, “She reached the top of Everest without extra oxygen.”
Perez is only the sixth woman to make the ascent without supplemental oxygen, the first from Latin America.
Until two weeks ago, Everest had been closed to climbers for more than a year following a 7.8 magnitude earthquake in April 2015 in Nepal. Sixteen sherpas died in an avalanche triggered by the quake.
