"On the 28th Dec 2008 Ueli Steck blasted his was up the north face of the Grandes Jorasses in another record time. Moving on from his 2.47hrs ascent of the Eiger north face in February earlier on this year he arrived in Chamonix on the 27th with his eyes on the north face classic- the Colton-Macintyre (VI,6)... Steck climbs up a 1200m face, with some very bare and tricky mixed at the top and sections of 95 degree ice in the middle, at an approximate ascent rate of 10m a minute."
