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.[1] There are approximately 1,524 such peaks on Earth.[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 therefore do not achieve enough topographic prominence.

The term "Ultra" originated with earth scientist Stephen Fry, from his studies of the prominence of peaks in Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least 1,500 metres (4,900 ft) of prominence.[3]

Map of Ultras
Map of Ultras worldwide


Currently, 1,515 Ultras have been identified above sea level: 637 in Asia, 353 in North America, 209 in South America, 119 in Europe (including the Caucasus), 84 in Africa, 69 in Australasia and 39 in Antarctica.[2]

Many of the world's largest mountains are Ultras, including Mount Everest, K2, Kilimanjaro, Mont Blanc, and Mount Olympus. On the other hand, others such as the Eiger and the Matterhorn are not Ultras because they do not have sufficient prominence. 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. In British Columbia, some of the mountains listed do not even have generally recognized names.

Thirteen of the fourteen 8,000m summits are Ultras (the exception being Lhotse), and there are a further 64 Ultras over 7,000 metres (23,000 ft) in height. There are 90 Ultras with a prominence of over 3,000 metres (9,800 ft), but only 22 with more than 4,000 metres (13,000 ft) prominence.

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.[3][4]

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.

Deep Creek Mountains

The Deep Creek Mountains, officially the Deep Creek Range (Goshute: Pi'a-roi-ya-bi), are a mountain range in the Great Basin located in extreme western Tooele County and Juab County, Utah, in the western United States.

The range trends north-south, (with a curl to the west at the southern end, 16% of range in White Pine County, Nevada), and is composed of granite in its central highest portion. The valley to the east is Snake Valley and to the west is Deep Creek Valley. Nearby communities include Callao, Utah to the east and the community of Ibapah and the lands of the Confederated Tribes of the Goshute Reservation to the west.

The highest point in the Deep Creek Range is Ibapah Peak, an ultra prominent peak, which rises to 12,087 feet (3,684 m). Other peaks include Haystack Peak at 12,020 feet (3,660 m) and Red Mountain at 11,588 feet (3,532 m). The range is the source of several perennial streams and supports a diverse coniferous forest, with an "island" of alpine tundra on the highest summits. The range has a vertical relief of 7,800 feet (2,400 m) above the salt flats of the Great Salt Lake Desert lying to the northeast and rises about 6,000 feet (1,800 m) above the semiarid plains to the west.

Doi Inthanon

Doi Inthanon (Thai: ดอยอินทนนท์, pronounced [dɔ̄ːj ʔīn.tʰā.nōn]) is the highest mountain in Thailand. It is in Chom Thong District, Chiang Mai Province.

The name Doi Inthanon was given in honour of Inthawichayanon, last King of Chiang Mai, who was concerned about the forests in the north and tried to preserve them. He ordered that after his death his remains be interred at Doi Luang, which was then renamed in his honour.

Today, the summit of Doi Inthanon is a popular tourist destination for both foreign and Thai tourists, with a peak of 12,000 visitors visiting the summit on New Year's Day. In addition to a range of tourist facilities on the summit, there is also a Royal Thai Air Force weather radar station at the summit and the Thai National Observatory (TNO) at km44.

The M'Goun mountain, also rendered as Ighil Mgoun / Ighil M’Goun / Irhil M’Goun (in tifinagh ⵉⵖⵉⵍ ⵎⴳⵯⵏ), Ighil n’Oumsoud, Jebel Mgoun, Jebel Ighil M’Goun and Jebel Aït M’goun, at 4,071 metres (13,356 ft) is the third highest peak of the Atlas Mountains after Toubkal and Ouenkrim).

It is an ultra prominent peak located in the Drâa-Tafilalet region of Morocco.

Mount Bahaya

Mount Bahaya (Somali language: Buurta Baxaya, sometimes spelled Mount Bahaja), also known as Mount Karkoor, is the fourth-tallest mountain in Somalia, after the triple-peaked mountains Mount Shimbiris, Mount Surud Cad, and Mount Warraq. It is the only Ultra-prominent peak in the country with a summit of about 2,100 m (6,900 ft). It is located in the northern Bari region, 60 kilometres (37 mi) east of Bosaso, and 20 kilometres (12 mi) southwest of Qandala, close to the Red Sea. The exact elevation is uncertain, being either 2,065 m (6,775 ft), 2,084 m (6,837 ft), or 2,120 m (6,960 ft). According to one 1974 map from the Defense Mapping Agency, it could even be 2,135 m (7,005 ft) in height.

With a prominence of 1,543 to 1,613 meters, it is an Ultra-prominent peak, making it the 74th to 58th most prominent peak in Africa, and the only definite one in the country of Somalia. The taller Mount Shimbiris could possibly be an Ultra-prominent peak as well, with a measured prominence of 1,495 m (4,905 ft). The mountain is highly elongated in a northwest-southeast direction, leading some to list the southern and northern ends as Bahaya and Karkoor, respectively.Mount Bahaya is the tallest peak in the Fadhisame Mountains, which are in northeastern Somalia. The range itself is a small section of the larger Ogo Mountains, which define the northern Horn of Africa in most of Somalia, and which extend further east, their peaks forming the Socotra Archipelago. Bahaya, along with the surrounding range, is mostly made up of the deeply-eroded remnants of an ancient volcanic chain.

Mount Ellen (Utah)

Mount Ellen is a mountain located in Garfield County, Utah. The high point of Mount Ellen's North Summit Ridge is the highest point in the Henry Mountains; it is also the highest point in Garfield County. It can be reached by a short hike from an unpaved road. These mountains were the last to be surveyed by the USGS in the lower 48 states. The mountain can be seen from as far as Mount Peale in the La Sal Mountains of eastern Utah.

Mount Ellen is an ultra prominent peak, meaning that it has more than 1,500 metres (4,921 ft) of topographic prominence, standing out considerably from nearby mountains. It stands in the watershed of the Fremont River, which together with Muddy Creek forms the Dirty Devil River, which drains into the Colorado River, and ultimately into the Gulf of California in Mexico.

The Paiute name for Mount Ellen was Un tar re. It was also referred to as First Mountain. After climbing to the summit in June 1872, Almon Harris Thompson named it for his wife Ellen. Ellen Powell Thompson was also the sister of explorer John Wesley Powell.Over several days beginning on September 10th, 1895 a detachment of the U.S. Army Signal Corps established the world heliograph record from stations atop Mount Ellen, Utah and Mount Uncompahgre, Colorado. The record for visual signalling was established utilizing mirrors 8 inches across and telescopes. The flashing signals communicated over a distance of 183 miles.

Discovered by the British National Antarctic Expedition of 1901–1904), it is named for Sir Clements Markham, who, as President of the Royal Geographical Society, planned the expedition and chose Robert Falcon Scott as its leader.

Mount Markham is the fourth-highest ultra prominent peak in Antarctica.
