The Rosenlaui gorge near Meiringen in Switzerland originates from the contact zone between fractured shale and compact limestone, that was deposited in a marine environment up to 250 million years ago. At this time, the region was a shallow ocean. Today’s torrent of the Rosenlaui glacier carved impressive domes into the limestone, formed circular potholes and erosive undercuts. The undercuttings receive no direct sunlight. Flowing and freezing water cracks and fractures the bedrock. Water is seeping from the walls and forms small waterfalls. Mosses nourish on the limestone in the cool and wet air.
