Walking from Söllereck to Riezlern takes you through a fascinating Alpine landscape. The trail from the mountain station down to Riezlern follows a glacial moraine ridge from the last Ice Age, 15,000 years ago. The water-retaining subsoil containing various deposits like marl, clays and loam created the biodiverse hillside moors here.
The juxtaposition of rock strata of different ages shaped the varied landscape of Kleinwalsertal valley. The ‘Flysch rocks’ of the grass-covered mountains from Söllereck to Gehrenspitze mountain were formed roughly 70 million years ago, during the Penninic age. Its geology is markedly different to the the limestone landscape of the Hoher Ifen mountain and the Gottesacker plateau. Their stone is much older, porous and thus very permeable to water, having formed roughly 100 million years ago in the Helveticum.
The beauty of this diverse landscape created millions of years ago is apparent on this panoramic hike.
