"I found this amazing place through internet searching, but high quality pictures of this particular region were so few... When I decided to travel there, I wanted to take high quality close-ups to show the beauty of the area," Doroudian said in an interview with weather.com.

The salt formations are various in shape and color. Some areas of the caves grow stark white salt, while others are gray, pink and even orange. Some of the salt is spikey and grows upwards, some look like coral you might find when snorkeling in the ocean.

"The interesting shapes created by salt deposits during thousands of years are very diverse," the photographer said. "The diversity is both in terms of structure and demensions and in terms of color. Sometimes you feel that they are made of glass and gemstones."

Doroudian explained that sometimes people take the smaller salt rocks for souveniers or decoration. It's a popular tourist destination, and some travel to the salt caves for its purported health benefits. It's been called one of the most attractive places in Garmsar City.

There are 27 salt mines in Garmsar, making it home to 70 percent of the state's salt mines. The region provides Iran with much of its salt.

"The region is a sunny place and there is intense light," Doroudian explained. "This light collided with salt crystals [and] doubled. So the light control was very important to show the color, texture and details of the salts."

Doroudian plans to continue to photograph the wonders of nature. He also plans to document Iranian village life. For more of his work, follow him on Instagram.
