Ultra prominent peak


Ultra prominent peak

An ultra prominent peak, or Ultra for short, is a mountain with a topographic prominence of convert|1500|m|ft|0|lk=on or more. There are a total of roughly 1524 such peaks in the world. 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.

The term "Ultra" is due to earth scientist Stephen Fry, from his studies of the prominence of peaks in Washington state in the 1980s. His original term was "ultra major mountain", referring to peaks with at least convert|5000|ft|m|0|abbr=on of prominence.Adam Helman, "The Finest Peaks: Prominence and other Mountain Measures", Trafford, 2005, ISBN 1-4120-5994-1.]

Distribution

Currently, 1,524 Ultras have been identified worldwide: 654 in Asia, 357 in North America, 209 in South America, 119 in Europe (including the Caucasus), 84 in Africa, 54 in Australasia and 39 in Antarctica.cite web|url=http://www.peaklist.org/ultras.html|title=The Ultra-Prominences Page|work=Peaklist.org|author=Maizlish, A.]

Many of the world's largest or best-known mountains are Ultras, including Mount Everest, K2, Kilimanjaro, Mont Blanc, and Mount Olympus. On the other hand, many large and famous mountains such as the Eiger, the Matterhorn and Ben Nevis are not Ultras because they do not have sufficient relative height. Many Ultras lie in rarely-visited and inhospitable parts of the world, including 39 in Greenland, the high points of the Arctic islands of Novaya Zemlya and Jan Mayen and Spitsbergen and 136 in High Asia. In British Columbia, some of the mountains listed don't even have generally-recognised names.

A number of Ultras have yet to be climbed, with the Finisterre Range highpoint, Sauyr Zhotasy, Karlik Shan, (possibly) Mount Siple, and Gangkar Puensum being the most likely candidates for the most prominent unclimbed mountain in the world.cite web|url=http://www.peaklist.org/WWlists/ultras/antarctica.html|title=Antarctic Ultra-Prominent Summits|work=Peaklist.org|author=Maizlish, A. (See footnotes 3 and 10.)]

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.
