The main feature of Karst landscape is that of not having a hydrographic surface network. The only real visible watercourse is located in the Val Rosandra valley. The other short streams which can be found on our plateau disappear into the ground and then return to the surface after having completed a journey underground, creating a landscape that may seem in the eyes of anyone as a stony barren land full of potholes. The territory that we generically define Carso and that corresponds to the homonymous DOC wine area is actually divided into three areas: the Karst plateau in the strict sense (the Eocene limestone and red-clay zone), the sedimentary hills of marly (mixture of clay and limestone) arenaceous composition (where the Parovel company is located) and a Quaternary plain.
