Emerald Pool

Photo by Ben Prepelka

This crystal clear pool is located in Norris Basin of Yellowstone National Park, Wyoming. Emerald Pool gets its name from the greenish colored water. The lovely hue is created by sulfur deposits and algae growth that lines the pool's edges. This 30 foot deep pool is one of 10,000 geothermal features in the park. This 3,500 square mile area became America's first national park in 1872.
