K2 the most deadly mountain

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.
An Italian expedition finally succeeded in ascending to the summit of K2 via the Abruzzi Spur on July 31, 1954. The expedition was led by Ardito Desio, although the two climbers who actually reached the top were Lino Lacedelli and Achille Compagnoni.

The first person to climb all fourteen eight-thousanders was Reinhold Messner. He completed this task on October 16, 1986. As of 2010, a total of 21 people have followed through undisputed. This is an extremely hazardous feat.
