Ultra prominent peak

From Wikipedia, the free encyclopedia

An ultra prominent peak, or ultra for short, is a mountain with a topographic prominence of 1,500 metres (4,921 ft) or more. There are a total of roughly 1524 such peaks in the world.^[1] Some are famous even to non-climbers, such as Mount Everest, Aconcagua, and Mount McKinley (the top three by prominence) and Mount Whitney, while others are much more obscure. Some famous peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high passes and therefore do not achieve enough topographic prominence.

All of the seven summits are ultras by virtue of the fact that they are the high points of large landmasses. Each has its key col at or near sea level, resulting in a prominence value almost equal to its elevation.
