The north-western facing side of Grand Combin is entirely covered by eternal snows and glaciers which are prone to serac falls.The southern end of the space enclosed between these three ridges is an elevated plateau of great extent, where the snows accumulate and feed the Corbassière Glacier which descends thence for about ten kilometers to the north.At the south-east extremity of the plateau, the highest part of the enclosing ridge is surmounted by two conical summits, of which the higher south-west point (Grand Combin de Grafeneire) is 4,309 meters in height, while the neighbouring north-east summit (Aiguille du Croissant) is lower by less than 60 meters (4,260 metres).The first to commence the exploration of the great massif which separates the Val de Bagnes from the Val d'Entremont was Gottlieb Samuel Studer, of Berne, who on August 14, 1851 reached for the first time the summit of the Combin de Corbassière with the guide Joseph-Benjamin Fellay,[6] and has published an account of that and a subsequent excursion in Bergund Gletscher-Fahrten.The first complete ascent of Grand Combin was finally made on July 30, 1859 by Charles Sainte-Claire Deville with Daniel, Emmanuel and Gaspard Balleys, and Basile Dorsaz.
