Mount Everest rises 8,848.86 m above sea level - the highest point on Earth. Orbit the massif beside Lhotse and Nuptse and toggle the red death-zone band above 8,000 m, where the air holds only a third of sea-level oxygen.
Published figures: summit 8,848.86 m (2020 China-Nepal joint survey); first ascent by Edmund Hillary and Tenzing Norgay on 1953-05-29; the death zone above about 8,000 m holds roughly one third of sea-level oxygen.

Mount Everest 3D Explorer
This browser explorer shows Mount Everest as a schematic Himalayan massif: the 8,848.86 m summit beside its neighbours Lhotse and Nuptse, snow above the schematic snowline, and a translucent red band marking the death zone above 8,000 m.
Everest - Sagarmatha in Nepali, Chomolungma in Tibetan - stands on the Nepal / Tibet (China) border in the Mahalangur Himal range. Edmund Hillary and Tenzing Norgay made the first confirmed ascent on 1953-05-29. Above about 8,000 m the air pressure falls to roughly a third of sea level, which is why climbers call it the death zone, and the mountain still rises a few millimetres each year as the Indian plate pushes under Asia.

Frequently Asked Questions
How tall is Mount Everest?
8,848.86 m above sea level, per the 2020 China-Nepal joint survey - the highest point on Earth.
What is the death zone?
The altitude band above about 8,000 m where air pressure gives only about a third of sea-level oxygen - the human body cannot acclimatize there and most climbers use bottled oxygen.
Who climbed Everest first?
Edmund Hillary of New Zealand and Tenzing Norgay, a Sherpa of Nepal, reached the summit on 1953-05-29 via the southeast ridge.
Where is Everest exactly?
On the border of Nepal and Tibet (China) in the Mahalangur Himal section of the Himalaya - Sagarmatha in Nepali, Chomolungma in Tibetan.
Is Everest still growing?
Yes - the collision of the Indian and Eurasian plates lifts the Himalaya a few millimetres per year, though earthquakes can also change its height slightly.
Is this a terrain simulation?
No. It is an educational explorer using published figures - the ridge shapes and snowline are schematic teaching cues, not survey terrain.
