What is grand prismatic in Yellowstone park?

The Grand Prismatic Spring is the largest hot spring in the United States, and the third-largest in the world. It is located in the Midway Geyser Basin of Yellowstone National Park. The spring is about 121 feet (37 meters) deep and 370 feet (113 meters) in diameter. The Grand Prismatic Spring is famous for its vibrant colors, which are caused by different types of bacteria that live in the water. The bacteria produce pigments that absorb certain wavelengths of light, reflecting the colors that we see.

The Grand Prismatic Spring is a very popular tourist destination, and it is estimated that over two million people visit the spring each year. The spring is located about 1.5 miles (2.4 kilometers) from the Old Faithful Geyser, and it is a short walk from the Grand Prismatic Spring Overlook.
