According to NASA, as of March 2012, Nanga Parbat had a fatality rate of about 20%.
In July 1953, Austrian climber Hermann Buhl became the first to reach the summit. He did so alone, without oxygen, food, a tent or sleeping bag. Before him, 31 people had died attempting that feat.
But the mountain is better known for how fast it's growing.
"There is no other mountain in the world that is rising as fast as Nanga Parbat," Mike Searle, a University of Oxford geologist, told NASA.
