In Yuncheng, China, as temperatures rise in the spring, a salt lake known as the “China’s Dead Sea” changes colors and has become a popular tourist attraction.

The lake, which is said to be 500 million years old and spans approximately 120 square km., changes colors, particularly red, due to microorganisms called Dunaliella salina, a microalgae that appears in salt lakes in countries including the U.S., France and Iran.

In the case of Iran’s Lake Urmia, according to NASA’s Earth Observatory: “In the marine environment, Dunaliella salina appears green; however, in conditions of high salinity and light intensity, the microalgae turns red due to the production of protective carotenoids in the cells.”
