Grand Prismatic Spring in the Midway Geyser Basin. This spring is the third largest hydrothermal spring in the world, approximately 250 X 300 feet in size and about 160 feet deep. The water temperature is 160 F (70 C). The colors on the edges of the spring are due to thermophile microbial mats that grow in the mineral-rich waters.
