The Tsanfleuron Glacier (French Glacier de Zanfleuron ) is a glacier on the eastern flank of the Diablerets in the southwestern Bernese Alps , in the canton of Valais . This plateau glacier has a length of 3.1 km and in 1998 covered an area of ​​around 3.3 km².

location

The Tsanfleuron glacier has its origin at 3000  m above sea level. M. high summit of the Diablerets massif. With a relatively weak incline, it flows to the east, along the southern foot of the Oldenhorn . In 2006 the glacier tongue was at an altitude of around 2500  m . Towards the southwest, the glacier is connected to the small Diableretsgletscher ( Glacier des Diablerets in French ), which covers the summit area of ​​the Diableret with an area of ​​around 1 km². In the west, the small Prapio glacier extends below a rock face .

Although the glacier lies on the main European watershed , its meltwater flows exclusively into the Mediterranean via the Morge and the Rhone . The path into the Saane is blocked by a moraine wall on which the Tsanfleuron glacier borders the Sex Rouge glacier .

tourism

The Tsanfleuron Glacier is accessible by a cable car with two sections from the top of the Col du Pillon to the Sex Rouge ( 2940  m above sea level ). The Glacier 3000 ski area includes several ski lifts and chairlifts. A few years ago, skiing could still be done on the glacier well into summer. In the meantime, due to the dwindling glacier, the ski area is only open between the beginning of November and the beginning of May (as of 2017).

Origin of name

In the regional patois, Tsan denotes the highest alpine pasture on the border with the mountains, i.e. the highest flowering willow.

Little ice age

At the height of the Little Ice Age around 1850, the Tsanfleuron glacier extended more than 3 km further east to the region of the Sanetsch Pass . But since the glacier did not fill a valley, it was always relatively thin, which is why the ice here has retreated particularly quickly over the past 150 years. The glacier has released an extensive, smoothly polished rock field ( Lapis de Zanfleuron ), which has numerous characteristic shapes such as round humps and sometimes water-filled hollows and depressions and is hardly overgrown by vegetation.

Even the uppermost part of the glacier is no longer covered by firn snow in many summers these days and the ablation area thus extends over the entire glacier, which means that the glacier will no longer receive any appreciable supply of ice and will melt completely if the current trend continues.
