The answer is:
K2
K2 is the second-highest mountain on Earth (after Mount Everest). With a peak elevation of 8,611 metres (28,251 ft), it is located on the border between Pakistan's northern territories, and China. K2 is known as the Savage Mountain due to the difficulty of ascent and the fact that for every four people who reach the summit, one dies trying. Among the Eight-thousanders, K2 has the third highest climbing mortality rate.
