Hassan Sadpara PP (born Hassan Asad; April 1963 – 21 November 2016) was a Pakistani mountaineer and adventurer from Skardu in GB, Pakistan.
 He is the first Pakistani to have climbed six eight-thousanders including the world's highest peak Everest (8848m) besides K2 (8611m), Gasherbrum I (8080m), Gasherbrum II (8034m), Nanga Parbat (8126 m), Broad Peak (8051m).
 He is also credited for summiting five of the eight-thousanders without using supplemental oxygen.
 Contrary to initial reports, Hassan Sadpara clarified that he used supplemental oxygen during his Everest ascent due to bad weather.
 He died due to cancer on 21 November 2016 in Rawalpindi.
The Karakoram, or Karakorum is a large mountain range spanning the borders of Pakistan, India, and China, with the northwest extremity of the range extending to Afghanistan and Tajikistan.
 It is located in the regions of Gilgit–Baltistan (Pakistan), Ladakh (India), and southern Xinjiang (China), and reaches the Wakhan Corridor (Afghanistan).
 A part of the complex of ranges from the Hindu Kush to the Himalayan Range, it is one of the Greater Ranges of Asia.
 The Karakoram is home to the four most closely located peaks over 8000m in height on earth: K2, the second highest peak in the world at 8611 m , Gasherbrum I, Broad Peak and Gasherbrum II.
Nazir Sabir Urdu: نذیر صابر is a Pakistani mountaineer.
 He was born in Hunza.
 He has climbed Mount Everest and four of the five 8000 m peaks in Pakistan, including the world's second highest mountain K2 in 1981, Gasherbrum II 8035m, Broad Peak 8050m in 1982, and Gasherbrum I (Hidden Peak) 8068m in 1992.
 He became the first from Pakistan to have climbed Everest on 17 May 2000 as a team member on the Mountain Madness Everest Expedition led by Christine Boskoff from USA that also included famed Everest climber Peter Habeler of Austria and eight Canadians.
Gasherbrum I (Urdu: ‎ ; ), surveyed as K5 and also known as Hidden Peak, is the 11th highest mountain in the world at 8080 m above sea level.
 It is located on the Pakistani–Chinese border in Gilgit–Baltistan region of Pakistan and Xinjiang region of China.
 Gasherbrum I is part of the Gasherbrum massif, located in the Karakoram region of the Himalaya.
 Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain."
Carlos Soria Fontán (Ávila, Spain, February 5, 1939) is a Spanish mountain climber who, at 77 years of age, has taken up the challenge of becoming the oldest person in the world to reach the summits of the 14 highest mountains in the world.
 He is the only mountaineer to have ascended ten mountains of more than 8,000 meters after turning 60, and he is the oldest person in history to have successfully climbed the K2 (65 years old), Broad Peak (68), Makalu (69), Gasherbrum I (70), Manaslu (71 years old), Kanchenjunga (75 years old) and Annapurna (77 years old).
Adam Bielecki (born 12 May 1983) is a Polish alpine and high-altitude climber.
 He is known for the first winter ascents of the eight-thousanders: Gasherbrum I and Broad Peak.
Broad Peak (Urdu: ‎ ) is the 12th highest mountain in the world at 8051 m above sea level.
 The literal translation of "Broad Peak" to Falchan Kangri (ཨིྰན་ཨངརི་) is not accepted among the Balti people.
 The English name was introduced in 1892 by the British explorer Martin Conway, in reference to the similarly named Breithorn in the Alps.
Burji La (or Burji Pass) is a natural pass in mountains between Skardu and Deosai National Park in Gilgit Baltistan, Pakistan.
 Its elevation is 4816 meters.
 It is famous especially for its beautiful panoramic view of so many mountain peaks, including that of K2, Nanga Parbat, Masherbrum, Chogolisa, Laila Peak, Golden Peak, Gasherbrum I, Gasherbrum II, Gasherbrum IV and a part of Broad Peak mountain.
Gasherbrum (Urdu: گاشر برم‎ ) is a remote group of peaks located at the northeastern end of the Baltoro Glacier in the Karakoram range of the Himalaya on the border of the Chinese-administered Shaksgam Valley and the Gilgit-Baltistan territory of Pakistan.
 The massif contains three of the world's 8,000 metre peaks (if Broad Peak is included).
 Although the word "Gasherbrum" is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of Gasherbrum IV, it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain".
Machulo La is a mountain view point which is considered the most easiest way to view some of the most highest peaks of Himalayas and Karakoram mountains in a single glance such as K2, Broad Peak, Gasherbrum-I, Gasherbrum-II, Gasherbrum III, Gasherbrum IV, K7, K6 and Nanga Parbat.
