K2, also known as Mount Godwin-Austen or Chhogori (Balti: چھوغوری), is the second highest mountain in the world, after Mount Everest, at 8,611 metres (28,251 ft) above sea level. 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 due to the extreme difficulty of ascent. It has the second-highest fatality rate among the eight thousanders. With around 300 successful summits and 77 fatalities, about one person dies on the mountain for every four who summit. It is more difficult and hazardous to reach the peak of K2 from the Chinese side; thus, it is usually climbed from the Pakistani side. Unlike Annapurna, the mountain with the highest fatality-to-summit rate (191 summits and 61 fatalities), or the other eight thousanders, K2 has never been climbed during winter.
