The Full Story
Mount Everest, located on the Nepal-Tibet border in the Himalayas, is the highest point above sea level at 8,849 meters (29,032 feet), as resurveyed in 2020. However, "tallest" depends on the measurement: Mauna Kea in Hawaii measures 10,210 meters from its oceanic base to summit (only 4,207 m above water). By distance from Earth's center, Chimborazo in Ecuador "wins" at 6,384.4 km — because Earth bulges at the equator. Everest was first summited on May 29, 1953 by Edmund Hillary and Tenzing Norgay. As of 2023, over 6,000 people have reached the summit, but more than 300 have died trying. The summit temperature averages -36°C and wind speeds can exceed 280 km/h.
