The International Mountaineering and Climbing Federation (UIAA) recognises eight-thousanders as the 14 mountains that are more than 8,000 metres (26,247 ft) in height above sea level, and are considered to be sufficiently independent of neighbouring peaks. There is no precise definition of the criteria used to assess independence, and, since 2012, the UIAA has been involved in a process to consider whether the list should be expanded to 20 mountains. All eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits are in the death zone.
