title: Mount Everest
text: The first recorded efforts to reach Everest 's summit were made by British mountaineers . As Nepal did not allow foreigners into the country at the time , the British made several attempts on the north ridge route from the Tibetan side . After the first reconnaissance expedition by the British in 1921 reached 7,000 m ( 22,970 ft ) on the North Col , the 1922 expedition pushed the north ridge route up to 8,320 m ( 27,300 ft ) , marking the first time a human had climbed above 8,000 m ( 26,247 ft ) . Seven porters were killed in an avalanche on the descent from the North Col . The 1924 expedition resulted in one of the greatest mysteries on Everest to this day : George Mallory and Andrew Irvine made a final summit attempt on 8 June but never returned , sparking debate as to whether or not they were the first to reach the top . They had been spotted high on the mountain that day but disappeared in the clouds , never to be seen again , until Mallory 's body was found in 1999 at 8,155 m ( 26,755 ft ) on the north face . Tenzing Norgay and Edmund Hillary made the first official ascent of Everest in 1953 , using the southeast ridge route . Tenzing had reached 8,595 m ( 28,199 ft ) the previous year as a member of the 1952 Swiss expedition . The Chinese mountaineering team of Wang Fuzhou , Gonpo , and Qu Yinhua made the first reported ascent of the peak from the north ridge on 25 May 1960 .
