K2 (Urdu: کے ٹو, Kai Ṭū), also known as Mount Godwin-Austen or Chhogori (Balti and Urdu: چھوغوری, Chinese: 乔戈里峰 Qiáogēlǐ fēng), at 8,611 metres (28,251 ft) above sea level, is the second highest mountain in the world, after Mount Everest at 8,848 metres (29,029 ft). It is located on the China–Pakistan border between Baltistan in the Gilgit-Baltistan region of northern Pakistan, and the Taxkorgan Tajik Autonomous County of Xinjiang, China. K2 is the highest point of the Karakoram range and the highest point in both Pakistan and Xinjiang.
K2 is known as the Savage Mountain after George Bell, a climber on the 1953 American Expedition, told reporters "It's a savage mountain that tries to kill you." Of the five highest mountains in the world, K2 is the deadliest where approximately one person dies on the mountain for every four who reach the summit. Other names for K2 are The King of Mountains and The Mountaineers' Mountain., as well as The Mountain of Mountains after climber Reinhold Messner titled his book about K2 the same. K2 is the only eight thousand meter peak that has never been climbed during winter or from its East Face. Ascents have almost always been made in July and August, the warmest times of year; K2's more northern location makes it more susceptible to inclement and colder weather.
The peak has now been climbed by almost all of its ridges. Although the summit of Everest is at a higher altitude, K2 is a more difficult and dangerous climb, due in part to its more inclement weather and comparatively greater height from base to peak. As of June 2018, only 367 people have completed the ascent. 86 people have died attempting the climb according to the list maintained on the List of deaths on eight-thousanders.
