AI overview
An eight-thousander is a mountain that rises above 8,000 meters (26,247 feet) in elevation, and there are 14 of these peaks in the world, all located in the Himalayan and Karakoram mountain ranges of Asia. These mountains matter because they represent the most extreme mountaineering challenges on Earth, drawing climbers from around the world and serving as ultimate tests of human endurance and mountaineering skill.

The eight-thousanders are 14 mountains recognised by the International Mountaineering and Climbing Federation (UIAA) with summits that exceed in elevation above sea level and are sufficiently independent of neighbouring peaks as measured by topographic prominence. There is no formally agreed-upon definition of prominence, however, and at times the UIAA has considered whether the list of 8,000-metre peaks should be expanded to 20 peaks by including the major satellite peaks of the canonical 14 eight-thousanders. All of the Earth's eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits lie in the altitude range known as the death zone, where atmospheric oxygen pressure is insufficient to sustain human life for extended periods of time.
