Ultra-prominent peak
An ultra-prominent peak, or ultra for short, is a mountain summit with a topographic prominence of 1,500 metres (4,900 ft) or more; it is also called a P1500.[2] Some well-known peaks, such as the Matterhorn and Eiger, are not ultras because they are connected to higher mountains by high cols and thus do not achieve enough topographic prominence.The term "ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington in the 1980s.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, Jan Mayen and Spitsbergen, and many of the peaks of the Greater ranges of Asia.A number of ultras have yet to be climbed, with Sauyr Zhotasy, (possibly) Mount Siple, and Gangkar Puensum being the most likely candidates for the most prominent unclimbed mountain in the world.
