Formation of Lake Oeschinen

Lake Oeschinen was formed by several landslides from the flanks of the Fründenhorn and the Doldenhorn. Since 2007, Lake Oeschinen has been part of the extended UNESCO World Natural Heritage Site Swiss Alps Jungfrau-Aletsch.

Origin of Lake Oeschi

In the process, the masses of rubble that broke off at the Doldenhorn at an altitude of 2100 metres, with a volume of well over a hundred million cubic metres, formed a natural dam. The rock material is still permeable to water today, which is why Lake Oeschinen is drained underground.
