11. Gasherbrum I
Elevation: 8,078 meters
Also known as the Hidden Peak, Gasherbrum I is located on the border between Pakistan and China. Not to be confused with Gasherbrum II, it is the second highest peak in the Karakoram mountain range, the area with the most glaciers outside of the polar regions. The name is said to arise from ‘rgasha brum’ which means ‘beautiful mountain’ in the Balti language. The first people to climb to the summit were Pete Schoening and Andy Kauffman, back in 1958.
