Nepal contains most of the Himalayas, the highest mountain range in the world. Eight of the fourteen eight-thousanders are located in the country, either in whole or shared across a border with China or India. Nepal has the highest mountain in the world, Mount Everest at an astonishing height of 8848m as well as 1,310 peaks over 6,000 m height.
North of the Greater Himalayas in western Nepal, ~6,100 metre Tibetan Border Ranges form the Ganges-Brahmaputra divide, which the international border generally follows. South of the Greater Himalayas, Nepal has a High Mountain region of ~4,000 metre summits, then the Middle Hills and Mahabharat Range with 1,500 to 3,000 metre summits. South of the Mahabharats, an outer range of foothills with ~1,000 metre summits is called the Siwaliks or Churiya Hills.
K2, at 8,611 metres (28,251 ft) above sea level, is the second-highest mountain on Earth, after Mount Everest at 8,849 metres (29,032 ft). It lies in the Karakoram range, partially in the Gilgit-Baltistan region of Pakistan-administered Kashmir and partially in the China-administered Trans-Karakoram Tract in the Taxkorgan Tajik Autonomous County of Xinjiang.
Mount Everest is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point. Its elevation of 8,848.86 m was most recently established in 2020 by the Chinese and Nepali authorities.
The Seven Summits are the highest mountains on each of the seven traditional continents. On 30 April 1985, Richard Bass became the first climber to reach the summit of all seven.
The Presidential Range is a mountain range located in the White Mountains of the U.S. state of New Hampshire. Containing the highest peaks of the Whites, its most notable summits are named for American presidents, followed by prominent public figures of the 18th and 19th centuries. The Presidential Range is notorious for having some of the worst weather on Earth, mainly because of the unpredictability of high wind speeds and whiteout conditions on the higher summits. Because of the poor weather conditions, the Presidential Range is often used for mountaineering training for those who go on to climb some of the world's highest mountains, including K2 and Everest.
Cho Oyu is the sixth-highest mountain in the world at 8,188 metres (26,864 ft) above sea level. Cho Oyu means "Turquoise Goddess" in Tibetan. The mountain is the westernmost major peak of the Khumbu sub-section of the Mahalangur Himalaya 20 km west of Mount Everest. The mountain stands on the China Tibet–Nepal Koshi Pradesh border.
The eight-thousanders are the 14 mountains recognised by the International Mountaineering and Climbing Federation (UIAA) as being more than 8,000 metres (26,247 ft) in height above sea level, and sufficiently independent of neighbouring peaks. There is no precise definition of the criteria used to assess independence, and at times, the UIAA has considered whether the list should be expanded to 20 mountain peaks by including the major satellite peaks of eight-thousanders. All of the eight-thousanders are located in the Himalayan and Karakoram mountain ranges in Asia, and their summits lie in an altitude known as the death zone.
Dhaulagiri, located in Nepal, is the seventh highest mountain in the world at 8,167 metres (26,795 ft) above sea level, and the highest mountain within the borders of a single country. It was first climbed on 13 May 1960 by a Swiss-Austrian-Nepali expedition. Annapurna I is 34 km (21 mi) east of Dhaulagiri. The Kali Gandaki River flows between the two in the Kaligandaki Gorge, said to be the world's deepest. The town of Pokhara is south of the Annapurnas, an important regional center and the gateway for climbers and trekkers visiting both ranges as well as a tourist destination in its own right.
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak, and zenith are synonymous.
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. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. 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.
In the history of mountaineering, the world altitude record referred to the highest point on the Earth's surface which had been reached, regardless of whether that point was an actual summit. The world summit record referred to the highest mountain to have been successfully climbed. The terms are most commonly used in relation to the history of mountaineering in the Himalaya and Karakoram ranges, though modern evidence suggests that it was not until the 20th century that mountaineers in the Himalaya exceeded the heights which had been reached in the Andes. The altitude and summit records rose steadily during the early 20th century until 1953, when the ascent of Mount Everest made the concept obsolete.
