Traverse Karakoram, or Karakorum is a large mountain range spanning the borders between Pakistan, India and China, located in the regions of Gilgit–Baltistan (Pakistan), Ladakh (India), and Xinjiang region, (China). It is one of the Greater Ranges of Asia, a part of the greater Himalaya while north of the actual Himalaya Range.
The Karakoram Trekking is home to the highest concentration of peaks over eight kilometres (five miles) in height to be found anywhere on earth, including K2, the second highest peak of the world (8,611 m/28,251 ft). K2 is just 237 m (778 ft) lower than the 8,848 m (29,029 ft) tall Mount Everest.
The Karakoram Range is about 500 km (311 mi) in length, and is the most heavily glaciated part of the world outside the Polar Regions. The Siachen Glacier at 70 km and the Biafo Glacier at 63 km rank as the world's second and third longest glaciers outside the Polar Regions.
The Climbing Karakoram is bounded on the northeast by the edge of the Tibetan Plateau, and on the north by the Pamir Mountains. The southern boundary of the Karakoram is formed, west to east, by the Gilgit, Indus, and Shyok Rivers, which separate the range from the northwestern end of the Karakoram range Himalaya range proper as these rivers converge southwestward towards the plains of Pakistan.
Due to its altitude and ruggedness, the Karakoram Pass is much less inhabited than parts of the Himalayas further east. European explorers first visited early in the 19th century, followed by British surveyors starting in 1856.
The Muztagh Pass was crossed in 1887 by the expedition of Colonel Francis Younghusband and the valleys above the Hunza River were explored by General Sir George K. Cockerill in 1892. Explorations in the 1910s and 1920s established most of the geography of the region.
