The travertine pools and terraces of Pamukkale, Turkey 18 Sep 2017
About this photo
Magical Pamukkale is actually a solidified cascade of travertine. The spectacle has been formed by calcium bicarbonate-laden hot springs just uphill. As the water has drained over the hillside and cooled, stalactite-festooned terraces and scallop-shaped pools have been formed. Over the years, considerable damage was done by too many tourists walking on the travertines, but now – in keeping with Pamukkale's status as a Unesco World Heritage Site – access to the terraces is highly restricted.
