K2 is the second highest mountain in the world, so, of course, climbing it won’t be easy. The climb is challenging because the sections of rock face are very steep and intertwines with ice pillars. They can collapse at any moment. Severe storms are common even in the summertime. "It's enormous, very high, incredibly steep and much further north than Everest which means it attracts notoriously bad weather," says Britain's most celebrated mountaineer Sir Chris Bonnington, who lost his colleague Nick Escourt in an avalanche on K2's western side during an expedition in 1978, according to The Independent.
