Karst topography
The Karst is the name given to the landscape above the Bay of Trieste up to the Alps.
Karst topography is known for underground rivers and caves. In fact the Karst landscape abounds in karst phenomena, such as swallow-holes with their disappearing streams, depressions in the land, and 15.000 caves, whose underground world is very rich in fauna (nowhere else in the world will you find an underground salamander “the human fish” Proteus anguinus). All geographical regions in the world which have karst phenomena are named after the Slovene Karst.
