The Otemma Glacier (including skin Emma glacier , French Glacier d'Otemma ) is a valley glacier in the southern Valais Alps in Switzerland . For 2011, the length of the glacier can be given as 7.4 km. Together with all its tributary glaciers , an area of 16.46 km² was determined in 1995. The exposure of the glacier is southwest.
The Otemma glacier has its origin on the southern flank of the Pigne d'Arolla . It then flows to the southwest and is flanked in the north by the peaks of the Portons (up to 3513 m above sea level ), in the south by the Aouille Tseuque ( 3554 m above sea level ) and the Singla ( 3714 m above sea level ) . The end of the glacier tongue was at an altitude of 2,460 m in 2007 . To the northeast of Otemma Glacier on the high alpine, ice-covered pass is the Col de Chermotane ( 3050 m above sea level. M. ) to the Mont Collon glacier connected. Several smaller side glaciers flow from the south, namely Glacier du Petit Mont Collon , Glacier de Blanchen , Glacier de l'Aiguillette and Glacier de l'Aouille . In the past, the Glacier de l'Epicoune and the Glacier de la Crête Sèche were also connected to the Otemma Glacier .
The Otemma glacier feeds the Dranse de Bagnes , whose water flows into the Lac de Mauvoisin reservoir . Since its peak during the Little Ice Age around the middle of the 19th century, the glacier has retreated about 3 km. When the Glacier de la Crête Sèche retreated around 1900, a marginal lake was dammed several times between the tongue and the lateral moraine of the Otemma glacier, which caused flood damage in the subsequent eruptions in the Val de Bagnes .
The central stage of the Haute Route between Chanrion and Zermatt runs over the Otemma glacier .
