China Salt Lake North China Salt Lake Turns Red

An ancient salt lake near the North China City of Yuncheng has recently turned red on one side, making it a famous tourist destination. Local officials say that the lake always turns red at this time of the year. It turned out that the red color comes from a kind of algae known as Dunaliella Salina. The salt lake, which formed about 500 million years ago, is the world’s third largest sodium Sulphate Inland Lake.
