Pamukkale, (cotton castle) natural hot spring travertine thermal mineral pools and terraces, Denizli, Turkey. Pammukale, originally the Greek city of Hierapolis, was built on top a natural travertine rock formation 2,700 metres (8,860 ft) long, 600 m (1,970 ft) wide and 160 m (525 ft) high. There is evidence that for thousands of years, people have been drawn to the attraction of the thermal pools. Pamukkale's terraces are made of travertine, a sedimentary rock deposited by mineral water from the 17 hot springs that spout mineral water with temperatures ranging from 35 °C (95 °F) to 100 °C (212 °F). When the water, supersaturated with calcium carbonate, reaches the surface, carbon dioxide de-gasses from it, and calcium carbonate is deposited. Calcium carbonate is deposited by the water as a soft gel which eventually crystallizes into travertine.
