Gashabrum  (also known as Hidden Peak or K5) is the 11th highest peak on Earth and the 3rd highest in Pakistan.Gashabrum I is part of the Gashabrum massif, located in the Karakoram region. Gashabrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gashabrum IV; but in fact it comes from "rgasha" (beautiful) and "brum" (mountain) in Balti, hence it actually means "beautiful mountain."
Gashabrum I was designated K5 (meaning the 5th peak of the Karakoram) by T.G. Montgomery 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.
Gashabrum I was first climbed on July 5, 1958 by Pete Schoening and Andy Kauffman of an eight-man American expedition led by Nicholas B. Clinch. Richard K. Irvin, Tom Nevison, Tom McCormack, Bob Swift and Gil Roberts were also members of the team. In the same year, the very first Moreover, the first ski descent from the top of an 8000 meter peak was Clinch and Schoening, climbs the use short ski and snow shoes.

Climbing history: In 1958 a strong Italian expedition led by Riccardo Cassin climbed Gasherbrum IV peak through north ridge after over-coming great climbing difficulties. It were mountaineers like Walter Bonatti and Carlo Mauri who successfully ached its top. They spent the whole night at camp-6 because of a severe snow storm. At day-time they came down to camp-5 (7,193m / 23,600ft) through a very dangerous route. It was one of the members of this party, Giuseppi de Francesch, who stopped himself from falling to his death from this mountain.
