The geological phenomenon in Pamukkale,Turkey ,literally "Cotton Castle" in Turkish . The Turkish name refers to the surface of the shimmering, snow-white limestone, shaped over millennia by calcium-rich springs. The water from these springs dripping slowly down the vast mountainside, mineral-rich waters foam and collect in terraces, spilling over cascades of stalactites into milky pools below. The reason for Pamukkale to be an attractive place is not only the natural travertine, but also the healing waters.
