The Oyster-shell Pools in Pamukkale
Pamukkale, meaning "cotton castle" in Turkish, is a natural site in Denizli in southwestern Turkey. The area is famous for a carbonate mineral left by the flowing water. Waters from ancient hot springs spilling down the hillside for a millennia have formed terraces of oyster-shell shaped pools, the white travertine constantly refreshed by the flow of the calcium rich waters.
