Surviving K2, one of the deadliest mountains in the world
At 28,251 feet, K2 is second to only Mount Everest as the tallest mountain in the world. Though 778 feet shorter than Everest, it's also much more dangerous, with a higher death rate than its taller counterpart. Four years ago, 11 climbers died during an attempt to scale the mountain, the deadliest recorded day in K2's history. The accident received widespread attention, but the extraordinary rescue that followed went unreported.
