The geology of the World is full of surprises and amazing.Ant Turkey is not an exception .You would be forgiven for thinking that this was a photo of an ice shelf. But it's not. It is a sprawling limestone formation called “Pamukkale” or “cotton Castle” in southwest Turkey. This place can be considered as one of the seven geological wonders of the World. Over the past 400,000 years, a complex of seventeen separate hot springs has been depositing snow white travertine limestone in a series of terraces and waterfalls.

The formation is over 2,700 metres long, 600 metres wide and 160 metres high. The springs are present due to the many cracks and fissures in the earth’s surface due to high tectonic activity. The temperature of the spring water as it emerges at the surface ranges between 35–56°C (95–133°F).
Flowing at a rate of 510 litres per second, the water is saturated with calcium carbonate, and as it reaches the surface carbon dioxide is released into the air, allowing the water to deposit the calcium carbonate until its carbon dioxide levels are balanced with those in the air. Initially deposited as a jelly-like substance, the calcium carbonate eventually hardens into travertine. The result is this beautiful landscape which is one of the major tourist attractions in Turkey.
Such an amazing and astonisihing wonder of the nature deserves a very big attraction from all who are intersted with such unbelivable scenes created by these gelocical formations.
