Gasherbrum I

 ( Eight-thousanders Of The Karakoram ) 

Gasherbrum I, originally surveyed as K5, and also known as Hidden Peak, is the 11th highest mountain in the world at above sea level. It is located between Shigar District in the Gilgit–Baltistan region of Pakistan and Tashkurgan in the Xinjiang province of China. Gasherbrum I is part of the Gasherbrum Massif, located in the Karakoram region of the Himalaya.

Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact, it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti language, hence it actually means "beautiful mountain".

Gasherbrum I was designated K5 (meaning the 5th peak of the Karakoram) by T.G. Montgomerie in 1856 when he first spotted the peaks of the Karakoram from more than 200 km away during the Great Trigonometric Survey of India. In 1892, William Martin Conway provided the alternate name, Hidden Peak, in reference to its extreme remoteness, due to which it remains hidden behind anterior peaks of the Gasherbrum group for most of the way along the Baltoro Glacier.

Gasherbrum I was first climbed on July 5, 1958, by Pete Schoening and Andy Kauffman of an eight-man United States expedition led by Nicholas Clinch, Richard K. Irvin, Tom Nevison, Tom McCormack, Bob Swift and Gil Roberts were also members of the team.
