Its peak is on the border of Nepal and China. It is above the Death Zone where the air is too thin for a human being, so usually extra oxygen is used when climbing. The Death Zone refers to the parts of Mount Everest that are above 7,600m (25,000ft) above sea level.
Two other mountains also can be named as "highest" mountains - the volcano Mauna Kea on Hawaii island is the highest mountain measured from the base underwater to the summit (more than 11 kilometres), and the summit of Chimborazo is the fixed point on Earth which is the greatest distance from the center - because of the modified ball shape of the planet Earth which is "thicker" around the Equator than measured around the poles.
A survey of India in 1856 recorded Everest. It was called Peak XV. This first published height was 8,840 m (29,000 ft). Everest was given its official English name in 1865 by the Royal Geographical Society.
British people began exploring the area around Mount Everest in 1921. The first expedition to try to climb to the top of Everest was in 1922. On June 8th, 1924, George Leigh Mallory and climbing partner Andrew Irvine tried to climb to the summit of Mount Everest. They disappeared into the fog and were not seen again until Mallory's dead body was found by Conrad Anker in 1999. To this day, no one is sure whether or not Mallory and Irvine made it to the summit before dying, 29 years before the next climbers would reach the summit.
The Sherpas are the local people who live at the foot of Mount Everest and not the porters who carry the climbers' luggage. For the Sherpas, Mount Everest is a sacred mountain and before they climb Mount Everest they always do a sacrificial offering.
