Yellowstone National Park is home to many natural wonders, but none is as impressive as Grand Prismatic Spring. This largest hot spring pot in the U.S. and one of the largest in the world is known for its vibrant colors and is a breathtaking spectacle for any visitor. The colors of Grand Prismatic Spring are a mesmerizing display of deep blues, greens, oranges and reds. The hues are created by mineral deposits in the water of the spring pot and the sunlight shining on the steam and water. The colors are best seen when the sun is highest and the steam is least dense, creating a fascinating and colorful effect.
