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.
