K2 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.
K2 is known as the Savage Mountain due to the difficulty of ascent and the second-highest fatality rate among the "eight thousanders" for those who climb it. For every four people who have reached the summit, one has died trying. Unlike Annapurna, the mountain with the highest fatality rate, K2 has never been climbed in winter.
