"These two expeditions were incredible. We climbed them with just a week's gap. It was the first time that I had shared an expedition with a woman and a great friend, Gerlinde Kaltenbrunner.
Gasherbrum I is a complicated mountain and it was much more difficult for us to climb than her sister Gasherbrum II."
First ascent: by an American expedition on 5 July 1958 led by Nich Clinch in which Pete Schoening and Andy Kauffman reached the peak.
The fifth peak of Karakoram (K5) was the last one chosen by Pasaban to close 2003 a successful year for the woman from Gipuzkoa, with three 'eight-thousanders'.
Gasherbrum I was originally called K5 (fifth peak of Karakoram) by T.G. Montgomery in 1856 when he saw the peaks of the Karakoram mountain range for the first time. In 1892, William Martin Conway gave it another name, Hidden Peak, in reference to its extreme remoteness.
Peak reached by Edurne Pasaban on 26 July 2003.
