World altitude record (mountaineering)
In the history of mountaineering, the world altitude record referred to the highest point on the Earth's surface which had been reached, regardless of whether that point was an actual summit. The world summit record referred to the highest mountain to have been successfully climbed. The terms are most commonly used in relation to the history of mountaineering in the Himalaya and Karakoram ranges, though modern evidence suggests that it was not until the 20th century that mountaineers in the Himalaya exceeded the heights which had been reached in the Andes. The altitude and summit records rose steadily during the early 20th century until 1953, when the ascent of Mount Everest made the concept obsolete.
