A detail of waterfalls over tufa barriers at Plitvice Lakes National Park in Croatia. The process of tufa formation, which in turn forms tufa barriers and creates the lakes, is part of the outstanding universal value for which Plitvice Lakes National Park was inscribed on the UNESCO World Heritage List.
