The brilliant blue, green, orange, yellow and red waters seep from the spectacular Grand Prismatic Spring in Yellowstone National Park. The colors are actually created by thermophiles that thrive in the hot spring water. Yellowstone National Park was the first national park to be established in 1872. These beautiful thermal pools are located in the Midway Geyser Basin near Old Faithful on the west side of the park in Wyoming. Wonderful boardwalks bring you to the edge of the largest thermal spring in Yellowstone.
