Salt Castles, Kuh-e-Namak, Bushehr, Iran
On the hillside of salt mountain (in Farsi, Kuh-e-namak) in southern Iran near the Persian Gulf you experience a weird feeling like you are on another planet because of the spectacular view unlike any other on the planet. There are no plants or animals, and you are surrounded by colorful spear-shaped salt crystal rocks like the one seen in the picture. You can also see salt streams, salt falls, and salt caves with cabbage shaped salt formations.
A salt dome is formed when a thick bed of water soluble minerals vertically intrudes into the surrounding rock layers, forming a diapir.
