Pamukkale [cotton castle in english] is a beautiful calcium formation that looks like snow or cotton. This model was made with Agisoft software using 93 frames from this video - https://www.youtube.com/watch?v=Y3SACYjAu7U
I can also say that I've been there once and I loved this place! From my view this place was huge and the waters were very warm. I recommend going there if you have a chance, there's also a nice castle above the Pamukkale hill.
