7. Chogori Peak (Xinjiang)

Chogori Peak, 8,611 meters in Yecheng County, Kashgar (Kashi) Region of Xinjiang Uygur Autonomous Region, is a transliteration of the Tajik language, meaning ''high, great and magnificent.'' Internationally, it is better known as K2, which is the only major mountain in the world that has surveyor's notation as its common name (K stands for Karakoram, 2 means it was the second peak listed).

It is known as the Savage Mountain due to its extreme difficulty of ascent and has 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 the winter.
