Today, most travelers come to marvel at the landscape's surreal charm. Yuncheng Salt Lake is filled with sulfates, which support a lush ecosystem. In the summer, algae blooms turn the water technicolor thanks to Dunaliella salina, an algae species that changes color when it reacts with salt. In winter, when the temperature dips below-5 C, the salt forms crystals of mirabilite, transforming the landscape into a twinkling winter fantasy.
