Xiechi Lake (Chinese: 解池), also called Yuncheng yanchi (Yuncheng Salt Lake) is the largest natural lake in Shanxi in Northern China. It is a saline lake[1] used for production of salt.

In the summertime intense light and heat cause the bacterium Dunaliella salina to produce carotenoids as a protection against free radicals, due in turn to high metabolism. This turns the salt pans brilliant shades of violet, scarlet, magenta, and emerald (see photo in reference).[2]
