Pamukkale Travertines
Water at about 35°C comes out of the ground here carrying dissolved calcium bicarbonate, loses its carbon dioxide as it runs down the hillside, and leaves calcium carbonate behind. Over something like fourteen thousand years that has built a white cliff 2,700 metres long and 160 metres high, terraced into basins that hold shallow warm water. The Turkish name means cotton castle. Until the 1990s hotels stood on top of it and cars drove up; those were demolished, the water is now rotated between sections to keep them white, and visitors walk the marked path barefoot, which is the condition of the place surviving at all.
