Francys Arsentiev was the first American woman to summit Mount Everest without supplemental oxygen. Her death on the descent made her story one of the most famous tragedies in Everest history.

What it is

Francys Arsentiev was an American mountaineer born January 18, 1958, in Honolulu, Hawaii. On May 22, 1998, she reached the summit of Mount Everest without using bottled oxygen, a feat that made her the first American woman to do so. Her success was part of an expedition with her husband, Sergei Arsentiev. Two days later, she died while descending the mountain.

Why it matters

Arsentiev's climb highlighted the extreme risks of high-altitude mountaineering, especially without supplemental oxygen. Her death, along with her husband’s, raised ethical questions about rescue obligations in the death zone. Her body remained visible on Everest for years, becoming known as the “Sleeping Beauty of Everest” and a somber landmark for climbers. The story remains a frequent topic in Canadian outdoor and expedition coverage.

Key details

Arsentiev died on May 24, 1998, from exposure and altitude-related distress near the summit. Her husband, Sergei, died during the same expedition. Attempts to move her body failed until 2007, when it was reportedly relocated out of view. The nickname “Sleeping Beauty” comes from her appearance—curled up as if asleep. Other climbers passed her body for years, adding to Everest’s grim lore.

In short

  • First American woman to summit Everest without bottled oxygen (1998)
