The Conca delle Carsene is a karst plateau in the Maritime Alps characterized by limestone rocks, the absence of surface watercourses, and the presence of sinkholes and swallow holes. Surface water is absorbed underground and resurfaces as the Pis del Pesio spring, sometimes fed by areas located beyond the Alpine divide.
