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.
Lhotse is the fourth-highest mountain on Earth, after Mount Everest, K2, and Kangchenjunga. At an elevation of 8,516 metres (27,940 ft) above sea level, the main summit is on the border between Tibet Autonomous Region of China and the Khumbu region of Nepal.
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.
Manaslu is the eighth-highest mountain in the world at 8,163 metres (26,781 ft) above sea level. It is in the Mansiri Himal, part of the Nepalese Himalayas, in west-central Nepal. Manaslu means "mountain of the spirit" and the word is derived from the Sanskrit word manasa, meaning "intellect" or "soul". Manaslu was first climbed on May 9, 1956, by Toshio Imanishi and Gyalzen Norbu, members of a Japanese expedition. It is said that, given the many unsuccessful attempts by the British to climb Everest before Nepali Tenzing Norgay and New Zealander Edmund Hillary, "just as the British consider Everest their mountain, Manaslu has always been a Japanese mountain".
Anatoli Nikolaevich Boukreev was a Soviet and Kazakh mountaineer who made ascents of 10 of the 14 eight-thousander peaks—those above 8,000 m (26,247 ft)—without supplemental oxygen. From 1989 through 1997, he made 18 successful ascents of peaks above 8,000 m.
Scott Eugene Fischer was an American mountaineer and mountain guide. He was renowned for ascending the world's highest mountains without supplemental oxygen. Fischer and Wally Berg were the first Americans to summit Lhotse, the world's fourth highest peak. Fischer, Charley Mace, and Ed Viesturs summitted K2 without supplemental oxygen. Fischer first climbed Mount Everest in 1994 and later died during the 1996 blizzard on Everest while descending from the peak.
Alan Hinkes OBE is an English Himalayan high-altitude mountaineer from Northallerton in North Yorkshire. He is the first British mountaineer to claim all 14 Himalayan eight-thousanders, which he did on 30 May 2005.
Andrew James Lock OAM is an Australian mountaineer. He became the first, and still remains the only, Australian to climb all 14 "eight-thousanders" on 2 October 2009, and is the 18th person to ever complete this feat. He climbed 13 of the 14 without bottled oxygen, only using it on Mount Everest, which he has summited three times. He retired from eight-thousander climbing in 2012.
Expedition climbing, is a type of mountaineering that uses a series of well-stocked camps on the mountain that lead to the summit, and which are supplied by teams of mountain porters. In addition, expedition climbing can also employ multiple 'climbing teams' to work on the climbing route—not all of whom are expected to make the summit—and allows the use of supports such as fixed ropes, aluminum ladders, supplementary oxygen, and sherpa climbers. By its nature, expedition climbing often requires weeks to complete a given climbing route, and months of pre-planning given the greater scale of people and equipment that need to be coordinated for the climb.
Lopsang Jangbu Sherpa was a Nepalese Sherpa mountaineering guide, climber and porter, best known for his work as the climbing Sirdar for Scott Fischer's Mountain Madness expedition to Everest in Spring 1996, when a freak storm led to the deaths of eight climbers from several expeditions, considered one of the worst disasters in the history of Everest mountaineering. Notwithstanding controversy over his actions during that expedition, Lopsang was well-regarded in the mountaineering community, having summited Everest four times. Lopsang was killed in an avalanche in September 1996, while again on an expedition to climb Everest for what would have been a fifth ascent.
Ralf Dujmovits is a German mountaineer. In May 2009 he became the 16th person, and the first German, to climb the 14 eight-thousanders.
Adrian Ballinger is a British-American certified IFMGA/AMGA mountain guide, certified through the American Mountain Guides Association and a sponsored climber and skier. Ballinger is the founder and CEO of Alpenglow Expeditions, and has been guiding full-time for 25 years. He has led over 150 international climbing expeditions on six continents, and made 18 successful summits of 8,000m peaks. He is known for pioneering the use of pre-acclimatization for commercial expeditions as early as 2012, which can cut the amount of time typically spent on an expedition in half. Adrian is the only American to have made three successful ski descents of 8,000m peaks, including the first ski descent of Manaslu from its summit. He is also the fourth American to have summited both Mount Everest and K2 without the use of supplemental oxygen.
The Mount Everest climbing season of 2013 included 658 summits and 8 deaths. Due to avalanches in 2014 and 2015, this was the last big summiting year until 2016.
Nirmal Purja is a Nepal-born naturalised British mountaineer. Prior to taking on a career in mountaineering, he served in the British Army with the Brigade of Gurkhas followed by the Special Boat Service (SBS), the special forces unit of the Royal Navy. Purja is notable for having climbed all 14 eight-thousanders in a time of six months and six days with the aid of bottled oxygen. This was a record at the time of climbing, although it was broken in 2023 by Kristin Harila and Tenjen Sherpa, who summitted all 14 eight-thousanders in 92 days. Purja was the first person to reach the summits of Mount Everest, Lhotse and Makalu within 48 hours. In 2021, Purja, along with a team of nine other Nepalese climbers, completed the first winter ascent of K2.
Kristin Harila is a Norwegian mountaineer and former cross-country skier. During 2022–2023, she set multiple speed records for the ascent of all 14 eight-thousanders, which are the peaks in the world that are over 8,000 metres in elevation.
