Karakoram

The Karakoram (English: /ˌkɑːrəˈkɔːrəm, ˌkær-/, Urdu: [kaːɾaːkoːɾəm]) is a mountain range in Asia which spans the borders of Pakistan, China and India, with the north-western extremities extending into Afghanistan and Tajikistan. The Karakoram contains four of the fourteen eight-thousanders, the highest of which is K2, the second highest mountain on Earth. The Karakoram begins in the Wakhan Corridor in eastern Afghanistan and extends eastwards into Indian-administered Ladakh and Chinese-administered Aksai Chin, as well as the Chinese province of Xinjiang. Most of the Karakoram is located within the Pakistani-occupied Gilgit-Baltistan region. The Karakoram is bounded on the east by the Aksai Chin plateau, on the north-east by the edge of the Tibetan Plateau, and on the north by the river valleys of the Yarkand and Karakash rivers, beyond which lie the Kunlun Mountains. At the north-west corner are the Pamir Mountains, while to the west lies Hindu Kush. The southern boundary of the Karakoram is formed west to east by the Gilgit, Indus, and Shyok rivers, which separate the range from the north-western end of the Himalaya. These rivers flow north-west before making an abrupt turn south-westwards towards the plains of Pakistan. Roughly in the middle of the Karakoram range is the Karakoram Pass, which was part of a now unused trade route between Ladakh and Yarkand. The Karakoram lies north of the Kashmir Valley and forms part of the wider mountain system surrounding the valley, together with the Pir Panjal and Zanskar ranges. The range is about 500 km (311 mi) in length and is the most glaciated place on Earth outside the polar regions. The Siachen Glacier (76 km (47 mi) long) and Biafo Glacier (63 km (39 mi) long) are the second- and third-longest glaciers outside the polar regions. The Karakoram is the second-highest mountain range on Earth...
