History Lake Oeschinen

Lake Öschinen was formed by several landslides of the flanks of the Fründenhorn and the Doldenhorn. In the process, the debris masses with a volume of well over a hundred million cubic meters that broke off at the Doldenhorn at an altitude of 2100 meters formed a natural dam. The rock material is still permeable to water today, which is why Lake Oeschinen is drained underground. Since 2007, Lake Oeschinen has been part of the extended UNESCO World Natural Heritage Site Swiss Alps Jungfrau-Aletsch.
