K2 (also known as Chhogori/Qogir, Ketu/Kechu, Savage Mountain, Mountaineer`s Mountain and Mount Godwin-Austen) is the second-highest mountain on Earth, after Mount Everest. With a peak elevation of 8,611 m (28,251 feet), K2 is part of the Karakoram Range, and is located on the border between Baltistan, in the Gilgit–Baltistan region of Pakistan, and the Taxkorgan Tajik Autonomous County of Xinjiang, China. It is more hazardous to reach K2 from the Chinese side; thus, it is mostly climbed from the Pakistani side.
