Jashak Salt Dome

Jashak Salt Dome is a salt mountain located in the northern part of Jashak Mountain, standing at an elevation of 1350 meters, at the southern end of the Zagros Mountain Range. This salt dome spans twelve kilometers in length, four and a half kilometers in width, and covers an area of approximately 3650 hectares.

Jashak Salt Dome is situated between the Bardkhun and Kaki districts, between the counties of Deyr and Dashti. It is located 144 kilometers southeast of Bandar Bushehr, sixty kilometers away from Khourmoj city, and fifteen kilometers from Kaki city in Bushehr province. The village of Jashak is to the north, and the village of Gankhak-e Sheykhi is to the east of the salt dome.

This dome is one of the 114 salt domes in southern Iran, formed 600 million years ago at the end of the Precambrian geological epoch, making it a fossil landmark. 

Jashak Salt Dome is white in color, appearing like a snowy mountain on the eastern side of the Kangan to Bushehr Road. Other parts of this salt dome at the lower elevations of the mountain have orange, yellow, red, and gray streaks, indicating the presence of various metal elements. Therefore, it is also referred to as "Colored Salt."

Salt glaciers can be seen in the eastern part of the dome. Although they are not true glaciers due to the warm temperatures in southern Iran, they resemble glaciers. There are also beautiful salt waterfalls in the Jashak dome, where large salt crystals can be seen at certain times of the year, particularly in spring and summer. These waterfalls, like the glaciers, are not actual waterfalls but rather flowing salt.

Water erosion is remarkably evident throughout the Jashak Salt Dome. One example of this is the salt caves scattered around the dome, formed by the dissolution of salt deposits.

Another example of water erosion is the columns known as "Takht-e Div." Local legends surround the Jashak Salt Dome, particularly regarding Takht-e Div. Another notable feature is the "Cauliflower Valley," named for the orange and white crystalline salt formations in the salty springs resembling cauliflower.

The wildlife of Jashak Salt Dome includes wild goats, foxes, jackals, hyenas, and birds such as sandgrouse, partridges, bee-eaters, swallows, swifts, sparrows, and finches, as well as various reptile species.

Its plant life includes Astragalus, mountain almond, and sagebrush in some areas, while other regions feature shrubs like Ziziphus, tamarisk, and wild almond, along with lichen.
