2 3 1 Spaccato idrogeologioco semplificato del sistema carsico dell’Altopiano del Cansiglio-Cavallo (illustrazione di Alvise Rossi, Unione Speleologica Pordenonese CAI) Simplified hydrogeological cross-section of the Karst system of the Cansiglio-Cavallo Plateau (illustration by Alvise Rossi, Unione Speleologica Pordenonese CAI) Localizzazione del geosito “Sorgenti del Fiume Livenza” Location of the Livenza Springs Geosite Gorgazzo Santissima Molinetto Livenza 1 2 3 1 km The Livenza River Springs emerge at the base of the south-eastern escarpment of the Cansiglio-Cavallo Karst massif at an altitude of between 30 and 50 metres above sea level, forming the Livenza River. There are three sources: the Molinetto [1], the Santissima [2], and the Gorgazzo [3], close to one another but each different. They have average annual temperatures of 11°C, 9.5°C, and 10°C, respectively. The Santissima and Gorgazzo are located within the municipality of Polcenigo, while Molinetto is in that of Caneva and is so named because there was an 18th century mill there until the beginning of the last century, in which various types of grain were ground. These are the main points of emergence of the extensive local aquifer and represent one of the most well-known and interesting Karst hydrological systems in Italy, so much so that they have been included in the Regional Cadastre of Geosites and Regional Geoparks (CaRGeo) of the Autonomous Region of Friuli Venezia Giulia as a site of significant geological, scientific, and landscape interest. The Molinetto spring, also called “della Livenzetta” (to indicate the short branch of the Livenza before it joins the Santissima), is the least known of the three, but it plays an equally important role, given its direct connection to the Karst zone of Col de la Rizza in Candaglia. Rainwater from the mountain takes just over a week to emerge at this spring, following very long and tortuous underground paths.
