Qogir, Ketu, and Mount Godwin-Austen are other names for K2, whose most common names come from the fact that it is the second-tallest mountain in the world. The 'K' in K2 stands for the Karakoram, the mountain range in Pakistan and China in which the peak is found. The House's Chimney and the Black Pyramid are features of K2, which also possesses a different second-place record, behind the Annapurna Massif: it boasts the second-highest fatality rate among attempted climbers of any mountains above 8,000 meters.
