Grand Prismatic Spring

Grand Prismatic Spring is one of the largest and most colorful hot springs in the United States, located in Yellowstone National Park. It is famous for its vibrant colors, which are created by microbial mats that thrive in the mineral-rich, hot water. The spring can reach temperatures of over 160°F (70°C) and has a diameter of approximately 370 feet. Its blue center transitions to hues of orange, yellow, and green at the edges, depending on the temperature and types of microorganisms present. This natural wonder attracts visitors for its striking beauty and geothermal activity.
