K-2, “mountain of mountains,” as referred to by Reinhold Messner in the account of his 1979 ascent of this giant, is 8611 m. high.
K-2 is located in the heart of the Karakoram Range and can be seen in its entirety from Concordia.
This sublime pyramid sits at the head of the Godwin Austin Glacier which unites with a second glacier at Concordia to form the mighty Baltoro Glacier
