Mount Everest is located on the border of Nepal and China.
Everest is part of the Mahalangur Himal subrange of the Himalayas. Its summit lies on the international boundary between Nepal and China’s Tibet Autonomous Region. Nepal commonly calls the mountain Sagarmatha, while Tibetans call it Chomolungma, names that reflect the mountain’s importance in local cultures.
The mountain’s officially recognized elevation is 8,848.86 meters, or about 29,031.7 feet, according to a joint Nepal–China measurement announced in 2020. Earlier surveys produced slightly different figures because of changing methods, snow estimates, and definitions of the summit.
The first confirmed ascent was made in 1953 by New Zealander Edmund Hillary and Nepali Sherpa Tenzing Norgay, using the South Col route from Nepal. Everest is not the most technically difficult mountain for every climber, but its extreme altitude, storms, cold, avalanches, and crowding make expeditions dangerous. The summit is in the death zone, where supplemental oxygen is often used.
