One of the 6 winners of the Piolets d'Or 2013. The Mazeno Ridge of Nanga Parbat - at over 10km probably the longest ridge of any 8,000m peaks - was one of the most famous unclimbed lines on the great Himalayan mountains. Accompanied by Cathy O'Dowd (S Africa), Lhakpa Rangdu Sherpa, Lhakpa Zarok Sherpa and Lhakpa Nuru Sherpa (Nepal), British alpinists Sandy Allan and Rick Allen made a first summit bid from their bivouac at 7,200m but this proved unsuccessful and all but Allan and Allen gave up and made a difficult descent to the south. The British pair traversed the north flank to the summit and made a difficult descent of the Normal Route on the north flank, reaching the bottom after an alpine-style traverse lasting 18 days.
