Blue Eyed Earth
The Midway Geyser Basin's Grand Prismatic Spring is one of the largest hot springs in the world, measuring approximately 370 feet in size and around 121 feet deep (higher than a 10-story building). Only Frying Pan Lake in New Zealand and Boiling Lake in Dominica are larger.
Largest Hot Springs in America
Of all the stunning sights that Yellowstone has to offer, by far and away (IMHO) the most amazing and awe-inspiring in this 3rd largest hot spring in the world.

The Beauty of Bacteria
A slice of the colorful warm water runoff from Yellowstone's amazing Grand Prismatic Spring. The vivid colors in the spring are the result of microbial mats around the edges of the mineral-rich water. The multicolored layers get their hues from different species of thermophile (heat-loving) bacteria living in the progressively cooler water around the spring.
