K2 is the second highest mountain in the world at 8,611 metres (28,251 ft), after Mount Everest. It is located on the border between Baltistan, in the Gilgit–Baltistan region of northern Pakistan, and the Taxkorgan Tajik Autonomous County of Xinjiang, China. With a peak elevation of 8,611 m (28,251 feet), K2 is the highest point of the Karakoram Range and the highest point in Pakistan.
K2 is known as the Savage Mountain due to the extreme difficulty of ascent and the second-highest fatality rate among the eight thousanders. One in every four people who have attempted the summit have died trying. 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 (246 summits, 55 deaths), K2 has never been climbed during wintertime.
