Two of the UK's leading alpinists, Nick Bullock and Al Powell climbed a new route on Jirishanca (6126m) in the Cordillera Huayhuash this summer. The pair had first tried a line direct up the South East face in 2002, but were avalanched off the mountain in rising temperatures. This year, they returned to climb what has been described as "the most significant British ascent in South America since Mick Fowler and Chris Watts 1982 ascent of the South West Face of Taulliraju". The Jirishanca route involved vertical and overhanging rotten ice, difficult aid and is considered by both to be their hardest and most dangerous climb yet. Bullock's slide show takes place at Longland's Cafe (above Outside) in Hathersage on October 15 at 7.30pm. Bring a cushion.
