Comparable phenomena to those prevailing at the Plitvice Lakes exist at Rastoke (Slunj), at the Krka National Park, at the rivers Una and the Pliva in Bosnia and Herzegovina and at the Krushuna Falls in Bulgaria. The Band-e Amir lakes within the Hindu Kush mountain range form a similar system of lakes and dams, though diverging tufa formation processes prevail. Calc-sinter formation processes that have not emerged along a river flow can be observed at the Mammoth Hot Springs within Yellowstone National Park (USA) or at Pamukkale in Turkey. Jiuzhaigou is a nature reserve and national park located in the north of Sichuan, China. Also inscribed by UNESCO as a World Heritage Site, its landscape of cascading lakes is made up of high-altitude karsts shaped by glacial, hydrological and tectonic activity. The area around Ocho Rios Jamaica is another region famous for its calc-sinter rivers. Most popular, particularly with cruise ships, is Dunn's River Falls.
