Located in Yellowstone National Park, the Great Prism Hot Springs (also known as Big Iridescent Hot Springs) is the largest hot spring in the United States and the third largest in the world. The beauty of the big prism hot spring is that the color of the lake changes with the seasons. In spring, the surface of the lake changes from green to brilliant orange-red, which is due to microorganisms such as algae and pigmented bacteria living in mineral-rich water, and the proportion of chlorophyll and carotenoids in their bodies changes with the seasons, so the water shows different colors.
