Grand Prismatic Spring (left) and Excelsior Geyser (right). Grand Prismatic Spring displays a stunning rainbow of colors created by species of thermophilac (heat-loving) bacteria that thrive in narrow temperature ranges. The blue water in the center is too hot to support any bacterial life, while the outer orange rings are the coolest water. Grand Prismatic Spring is the largest spring in the United States and the third-largest in the world. Midway Geyser Basin.

Location: Midway Geyser Basin, Yellowstone National Park, Wyoming, USA | Morning Glory Pool has long been considered a must-see site in Yellowstone. At one time a road brought visitors to its brink. Over the years they threw coins, bottles and trash in the pool, reducing its flow and causing the red and orange bacteria to creep in from its edge, replacing the blue bacteria that thrive in the hotter water at the center of the pool. The pool is now accessed only by a foot path. Upper Geyser Basin.

Location: Upper Geyser Basin, Yellowstone National Park, Wyoming, USA | Crested Pool is a blue, superheated pool. Unfortunately, it has claimed a life. It reaches a overflowing boiling state every few minutes, then subsides a bit before building to a boil and overflow again. Upper Geyser Basin.

Castle Geyser erupts with the colorful bacteria mats of Tortoise Shell Spring in the foreground. Castle Geyser reaches 60 to 90 feet in height and lasts 20 minutes. While Castle Geyser has a 12 foot sinter cone that took 5,000 to 15,000 years to form, it is in fact situated atop geyserite terraces that themselves may have taken 200,000 years to form, making it likely the oldest active geyser in the park. Upper Geyser Basin.

Location: Midway Geyser Basin, Yellowstone National Park, Wyoming, USA | Grand Prismatic Spring displays brilliant colors along its edges, created by species of thermophilac (heat-loving) bacteria that thrive in narrow temperature ranges. The outer orange and red regions are the coolest water in the spring, where the overflow runs off. Midway Geyser Basin.
