Excellent catch, SunkenCiv! I hadn't made the connection, but I'm sure you're right.
Speaking of your FReeper name, did you see the pictures of Cleopatra's Pool downstream from the Pamukkale terraces? You can swim over broken columns from a Greek temple. The picture below is the best one I could find illustrating what I mean, but if you search Google images with the phrase "Pamukkale pool", you can see more.
