Grand Prismatic Spring (click to enlarge)

The Grand Prismatic Spring is the largest and one of the most brilliant of the many springs in Yellowstone. The temperature of the water is around 60°C. The yellow, orange and brown colors are caused by small heat-loving microorganisms, names thermophiles. The intense blue color in the center is because of the sunlight gets scattered by fine particles in the water. Simply beautiful!

Happy Heating 🙂
