The Corbassière Glacier (French Glacier de Corbassière ) is a valley glacier on the north side of the Grand Combin in the southwestern Valais Alps , in Switzerland . It is 9.7 km long and, together with its tributary glaciers, covers an area of around 16 km². This makes it the largest glacier in Lower Valais and the fifth longest in Switzerland after the Aletsch Glacier , the Fiescher Glacier , the Gorner Glacier and the Unteraar Glacier .
The Corbassière glacier has its origin on the north slope of the Grand Combin at over 4000 m above sea level. M. At an altitude of 3,300 to 3,400 meters There is a large, barely sloping ice surface, which in the west of the rocky peaks of the Maisons Blanches (up to 3682 m is limited). Then the glacier flows with a slight curve to the north, flanked by the peaks of the Combin de Corbassière ( 3716 m ) and Petit Combin ( 3663 m ) in the west and by Tournelon Blanc ( 3702 m ) and Grand Tavé ( 3158 m ) in the east. The Corbassière glacier drains through the Torrent de Corbassière into the Dranse de Bagnes , which flows through the Val de Bagnes to the Rhone .
In the early 19th century, in the late phase of the Little Ice Age , the glacier tongue reached down into the forest zone. Moraine remains are at an altitude of around 1800 m, not far from the confluence of the Dyure de Sery torrent. The glacier tongue ended in 2005 at around 2200 m . Since a peak in the mid-19th century, the glacier has retreated more than 1.5 km.
Cabane François-Xavier Bagnoud ( 2645 m , formerly called Cabane de Panossière ), which is the starting point for mountain climbs and glacier tours in the Grand Combin massif, stands on the lateral moraine on the eastern edge of the lower section of the glacier .
