    Grand Prismatic Spring in Midway Geyser Basin is not only the park’s largest hot spring – it is also largest in the United States and the third largest worldwide. Only Frying Pan Lake in New Zealand and Boiling Lake in Dominica outdo the Grand Prismatic Spring in size. It measures around 370 feet (113 meters) in diameter and is over 121 feet (37 meters) deep.



    The beautiful colors are made from microbial mats around the edges of the mineral-rich water. In summertime the edges range from red to orange, in wintertime it is more of a dark green. The deep blue color in the center of the spring results from its sterility and depth.

      The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world, after Frying Pan Lake in New Zealand and Boiling Lake in Dominica. It is located in the Midway Geyser Basin.

      Grand Prismatic Spring was noted by geologists working in the Hayden Geological Survey of 1871, and named by them for its striking coloration. Its colors match the rainbow dispersion of white light by an optical prism: red, orange, yellow, green, and blue.
