Grand Prismatic Spring

Grand Prismatic Spring is a large hot spring in the Midway Geyser Basin of Yellowstone National Park, in the United States. Bands of orange, yellow and green around its deep blue centre come from heat-loving microbes. Visitors walk the boardwalks around the basin and look down on the spring from nearby vantage points.
