The Wolayer Pass is the saddle that separates the imposing limestone cliffs of Mount Capolago/Seekopf to the west from those of Cima Lastrons del Lago/Seewarte und Coglians/Hohe Warte to the east. It owes its origins to an important tectonic line north-south, a fault that cuts the cliff deposits, remains of the oldest marine environments. A fault is a fracture within a rocky body, which testifies to the movements of the block in which the body was divided. This fault is characterised by a rather important vertical movement, but also by a relative horizontal displacement which is estimated in about half a kilometre (546 yards).
