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.

The Lower Falls of the Yellowstone River drops 308 feet at the head of the Grand Canyon of the Yellowstone. A long exposure blurs the fast-flowing water. The canyon is approximately 10,000 years old, 20 miles long, 1000 ft deep, and 2500 ft wide. Its yellow, orange and red-colored walls are due to oxidation of the various iron compounds in the soil, and to a lesser degree, sulfur content.

Location: British Columbia, Canada | 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.
