Looking north, you can see the Lambertenghi Ridge, the ridge west of the Volaia pass that connects to the north-east corner of Mount Capolago. It represents, in some ways, a synthesis of the geological makeup of the Volaia area. A thrust fault connects two different sedimentary sequences: one is made up by rocks that deposited in an open sea over a time frame going from the Upper Ordovician to the Lower Carboniferous. Another sequence is of equal age but constituted, especially in its Devonian part, by rocks deposited in lower sea environments.
