In the next 150 metres you will travel through 150 million years of Earth’s history. Look closely at the colours of the rocks! There are some that are a deep red and that settled on gigantic alluvial plains near the coasts about 260 million years ago, when the environment was characterized by desert conditions. There then follow the brownish rocks of the Auernig Formation rich in fossils, dating back to about 300 million years ago.
At the point where the Alta Via Carnica meets the Via delle Malghe, you can observe black rocks dating back to 410 million years ago from deeper marine strata.
