Despite this, Everest is safer for climbers than a number of peaks by some measurements, but it depends on the period. [263] Some examples are Kangchenjunga, K2, Annapurna, Nanga Parbat, and the Eiger (especially the nordwand). [263] Some factors that affect total mountain lethality include the level of popularity of the mountain, the skill of those climbing, and the difficulty of the climb.

During the 1996 season, 15 people died while climbing on Mount Everest. These were the highest death tolls for a single weather event, and for a single season, until the sixteen deaths in the 2014 Mount Everest avalanche. The guiding disaster gained wide publicity and raised questions about the commercialisation of climbing and the safety of guiding clients on Mount Everest. In 1802, the British began the Great Trigonometrical Survey of India to fix the locations, heights, and names of the world's highest mountains. Starting in southern India, the survey teams moved northward using giant theodolites, each weighing 500kg (1,100lb) and requiring 12 men to carry, to measure heights as accurately as possible. They reached the Himalayan foothills by the 1830s, but Nepal was unwilling to allow the British to enter the country due to suspicions of their intentions. Several requests by the surveyors to enter Nepal were denied. [16]

Debilitating effects of the death zone are so great that it takes most climbers up to 12 hours to walk the distance of 1.72 kilometres (1.07mi) from South Col to the summit. [255] Achieving even this level of performance requires prolonged altitude acclimatisation, which takes 40–60 days for a typical expedition. A sea-level dweller exposed to the atmospheric conditions at the altitude above 8,500m (27,900ft) without acclimatisation would likely lose consciousness within 2 to 3 minutes. [256] The 8,848m (29,029ft) height given was officially recognised by Nepal and China. [34] Nepal planned a new survey in 2019 to determine if the April 2015 Nepal earthquake affected the height of the mountain.
