K2 is the second-highest mountain on Earth, after Mount Everest. It is located on the border between Baltistan, in the Gilgit–Baltistan region of northern Pakistan, and the China. With a peak elevation of 8,611 m (28,251 feet), K2 is the highest point of the Karakoram Rangeand 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. For every four people who have reached the summit, one has 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, K2 has never been climbed in winter.
