Five Flower Lake, in Jiuzhaigou Valley, has an amazing range of blue colors produced by combining mineral deposits, algae, and different depths. On its floor, the lake's glistening clean waters expose old fallen trees preserved by their mineral-rich content. As sunlight interacts with various minerals and organic components in the lake, its unique colors vary throughout the day. Rich in calcium carbonate, the surrounding mountains' geological makeup produces travertine deposits that naturally block the lake and add to its unusual chemical composition. While the high mineral concentration helps preserve organic materials at the bottom, scientific research have discovered that the lake's intricate ecosystem includes uncommon types of algae that add to its multi-colored look. Being a UNESCO World Heritage site guarantees the lake's preservation, which enables scientists to investigate how biological processes mix with natural mineral deposits to produce such remarkable visual effects.
