Watch: On Dangerous K2 Mountain Where Dad Died, Pakistan Climber Now Cleans Garbage
Gazing up from K2 Basecamp, Sajid Ali Sadpara sees Earth's second-highest mountain, his father's final resting place, and a blight of litter on the furthest reaches of the natural world. Sajid dons a down coverall stitched with Pakistan's green flag to scale the 8,611-metre (28,251-foot) spur of rock, clearing an icebound grotesquerie of spent oxygen canisters, mangled tents and snarled rope discarded over decades by climbers questing for the summit.
