Simon Yates (with Andy Parkin, plus Celia Bull, Elaine Bull and Jane Yates in support). February-March 2001

Due to difficult access, poor maps and appalling weather, there have been few expeditions to the Cordillera Darwin range of mountains in Chilean Tierra del Fuego. This team sailed from Ushuaia in southern Argentina via the Beagle Channel to Bahia Yendegaia on Celia Bull's yacht, Ada II, and a base camp was established as far up the Yendegaia valley as horses could get. The climbing objective was selected from a photograph supplied by Dr David Hillebrandt, the NE face of a mountain thought to be Mont Bové, 2150m. They were successful in making the first ascent of this 900m route to the summit at Alpine ED, VI, but found that it was actually a separate peak, c.2200m on the ridge connecting Bové to the Roncagli summits. Unlike Bové, the mountain was unclimbed, and probably un-named, so they are proposing to call it Monte Ada.
