Looking south, we can observe the pale rocks of the Devonian cliffs of Monte Zermula and the Zuc della Guardia. The more rounded form of M. Pizzul, in the background, is due to its rocks being more of the open sea coeval with the reef and thus more easily eroded. These two sequences, deposited in relatively distant areas, are now almost in contact with each other as a result of the tectonic movements that led to the formation of the Alps.
