On the rock wall at the edge of the path, you will come across rocks of the Auernig Formation dating back about 300 million years ago and which formed the sea coast at a time when it was very populated with life. These rocks are made up of marine and coastal sediments and here it is possible to observe both. In the lower part there are grey limestones laid down in a warm and not very deep sea. When the sea receded, the rivers brought sand that became consolidated, forming brown sandstones (visible here above the limestone). At the next stops you will discover more details about this rock formation.
