During the winter, sometimes a river runs through the valley from the lake in Villalago generating other smaller lakes, fed by rainwater and melting snow until late spring. The stretch of the valley of Sagittarius where is located the Lake of Scanno is between two large limestone massifs: the left whole of Big Mountain, while to the right the group of Mount Genzana – Monte Greek, instead characterized by calcareous – marl sediments.
