Mount Everest

Mount Everest. It is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The international border between Nepal and China runs across its summit point. Its elevation of 8,848.86 meters was officially recognized in a joint declaration by Nepal and the People's Republic of China in 2020, following surveys by both nations.

Geography and location

The peak lies within the Solukhumbu District of Nepal's Koshi Province and Tingri County in the Tibet Autonomous Region of China. It forms part of the colossal Himalayan mountain system, specifically within the Mahalangur Himal range. Key neighboring peaks include Lhotse, the world's fourth-highest mountain, and Nuptse, which together form a massive wall of rock and ice. The mountain is flanked by several significant glaciers, including the Khumbu Glacier on the Nepalese side and the Rongbuk Glacier in Tibet. Major features for climbers are the Western Cwm, a broad, flat glacial valley, and the Hillary Step, a near-vertical rock face just below the summit.

Geology and formation

The mountain is a product of the ongoing continental collision between the Indian Plate and the Eurasian Plate, a tectonic process that began roughly 50 million years ago and continues today. The rock comprising the summit pyramid is a limestone and marble formation deposited on the ancient sea floor of the Tethys Ocean. This sedimentary rock has been thrust upward and now rests atop younger rocks, a structure confirmed by the research of early geologists like Noel Odell. The mountain continues to rise a few millimeters each year due to tectonic forces, while simultaneous erosion from extreme weather and glacial activity also shapes its form.

Climbing history

The first recorded attempts to reach the summit were made by British expeditions in the 1920s, most notably the 1924 British Mount Everest expedition during which George Mallory and Andrew Irvine famously disappeared. The first confirmed ascent was achieved on May 29, 1953, by Tenzing Norgay of Nepal and Edmund Hillary of New Zealand, as part of a British expedition led by John Hunt. Major milestones since include the first ascent without supplemental oxygen by Reinhold Messner and Peter Habeler in 1978, and the first solo ascent by Reinhold Messner in 1980. The standard routes are the South Col route from Nepal and the North Col route from Tibet, with the Khumbu Icefall on the southern approach posing a persistent and deadly hazard.

Environmental concerns

The increasing popularity of commercial expeditions has led to severe pollution, with the mountain often described as the "world's highest garbage dump." The slopes are littered with discarded oxygen cylinders, abandoned tents, and human waste. In response, initiatives like the Sagarmatha Pollution Control Committee in Nepal and cleanup drives led by climbers such as Kami Rita Sherpa have been organized. Climate change is also having a profound impact, causing the retreat of critical glaciers like the Khumbu Glacier and potentially making the mountain more unstable and dangerous to climb. The government of Nepal now requires climbers to bring down a mandatory amount of their own trash.

Cultural significance

Known as Sagarmatha in Nepal and Chomolungma in Tibet, the mountain holds deep spiritual meaning for local peoples such as the Sherpa and Tibetan Buddhists. It is considered a sacred deity and mother of the world. The entire region in Nepal is protected as part of Sagarmatha National Park, a UNESCO World Heritage Site. In global culture, it represents the ultimate physical challenge, a symbol of human endeavor featured in countless works of literature, film, and art. The annual climbing season draws international media attention, with records set by individuals like Junko Tabei, the first woman to summit, and Apa Sherpa, who holds the record for most ascents.
