Defined Alpine Terminology & Concepts
- Death Zone
- The altitude region above 8,000 meters where the barometric pressure drops so low that human lungs cannot absorb sufficient oxygen to survive indefinitely, causing irreversible cellular deterioration.
- Khumbu Icefall
- A steep, chaotic cascade of fractured glacial ice flowing from the Western Cwm down to Base Camp, moving up to a meter each day and creating towering, collapsible seracs.
- Hillary Step
- A famous 12-meter (39 ft) near-vertical rock face located on the Southeast Ridge at 8,790 meters, named after Sir Edmund Hillary and considered the final technical crux before the summit.

Documented Climbing Routes (5)
Mount Everest North Face (Hornbein Couloir Direct)
The North Face of Mount Everest via the Japanese Couloir and the sheer Hornbein Couloir is one of the most direct and formidable ice lines in the Himalayas. Rising 3,000 vertical meters from the Rongbuk Glacier to the summit, it funnels through a narrow 60-degree snow-and-ice cleft slicing straight through the Yellow Band and upper limestone cliffs of the North Face. In August 1986, Swiss alpinists Erhard Loretan and Jean Troillet executed one of the most audacious speed climbs in mountain history: climbing the entire face in a single 31-hour push at night without supplemental oxygen, tents, or fixed ropes. After summiting on August 30, they glissaded down the 3,000-meter face on their backs and buttocks in just 3.5 hours, completing the entire round trip in an astonishing 43 hours.
North Col & Northeast Ridge Route
The historic northern route on Mount Everest (8,848.86m), ascending from the Rongbuk and East Rongbuk glaciers to breach the icy wall of the North Col (7,020m). From the col, the route traverses the wind-blasted Northwest Ridge onto the North Face before joining the razor-like Northeast Ridge, navigating the notorious First, Second, and Third Steps in the Death Zone. This was the stage of George Mallory and Andrew Irvine's fateful 1924 climb and was first definitively surmounted on May 25, 1960, by Chinese climbers Wang Fuzhou, Qu Yinhua, and Gongbu.
Mount Everest Southwest Face (Bonington Route)
The Southwest Face of Mount Everest (8,848.86m) rises 2,300 vertical meters from the Western Cwm to the summit, presenting one of the largest and most forbidding rock and ice faces in the world. Dominated by the vertical 300-meter 'Rock Band' at 8,200β8,500 meters, the face repelled six international attempts between 1969 and 1974. In autumn 1975, a legendary British expedition led by Chris Bonington breached the face when Paul Braithwaite and Nick Estcourt unlocked the key ramp through the Rock Band. On September 24, 1975, Doug Scott and Dougal Haston climbed to the South Summit and pushed on to the main summit, becoming the first Britons to conquer Everest. Trapped by nightfall during their descent, they survived an epic open bivouac at 8,760 meters without oxygen, sleeping bags, or frostbite.
Mount Everest Complete West Ridge (Yugoslav Direct)
The Complete West Ridge of Mount Everest is one of the most formidable and sustained technical routes on the mountain. Pioneered in spring 1979 by an elite Yugoslav expedition led by Tone Ε karja, the route tackles the integral knife-edge crest directly from the Lho La col (6,026m) all the way to the 8,848.86m summit. Unlike the 1963 American West Ridge route which diverted into the Hornbein Couloir from the North Face, the Yugoslav line stayed strictly along the razor-edge crest of the West Ridge, surmounting technical rock buttresses up to Grade V+ at extreme altitude before traversing around the Yellow Band. On May 13, 1979, Andrej Ε tremfelj and Nejc Zaplotnik achieved the first ascent of the complete ridge, followed two days later by Stane Belak, Marjan Manfreda, and Ang Phu Sherpa in one of the greatest feats in Himalayan history.
South Col & Southeast Ridge (Normal Route)
The South Col Route along the Southeast Ridge is the historic path of the 1953 first ascent and the most popular route on Mount Everest. Starting from Base Camp on the Khumbu Glacier in Nepal, climbers navigate the shifting seracs of the Khumbu Icefall into the Western Cwm. The route then scales the icy 45-degree slope of the Lhotse Face to the South Col at 7,925 meters, launching the final summit bid through the Balcony, South Summit, and Hillary Step to the summit of Earth at 8,848.86 meters.

Frequently Asked Questions: Mount Everest
What is the official height of Mount Everest?
Mount Everest stands at an official elevation of 8,848.86 meters (29,031.7 feet), established through a joint geodetic and satellite survey conducted by Nepal and China in December 2020.
What is the Death Zone on Mount Everest and where does it begin?
The Death Zone begins at 8,000 meters (26,247 feet), above the South Col. At this extreme altitude, atmospheric pressure drops to roughly one-third of sea-level value, preventing human acclimatization and making survival without supplemental oxygen unsustainable beyond 24 to 48 hours.
Who were the first climbers to officially summit Mount Everest?
Sir Edmund Hillary of New Zealand and Tenzing Norgay of Nepal completed the first confirmed summit ascent on May 29, 1953, via the South Col and Southeast Ridge as part of the ninth British Everest Expedition led by John Hunt.
What are the traditional local names for Mount Everest?
In Nepal, the mountain is named Sagarmatha (Sanskrit/Nepali for "Goddess of the Sky"). In Tibet and the Sherpa language, it has been revered for centuries as Chomolungma or Qomolangma ("Mother Goddess of the World").
What is the most dangerous section on the standard Everest climbing route?
The Khumbu Icefall, located between 5,400m and 5,800m, is widely regarded as the most unpredictable and dangerous section due to constantly shifting glacial seracs, widening crevasses, and frequent ice avalanches.
