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.

Excelsior Geyser, now dormant, was formerly the worlds largest geyser. It still produces immense runoff into the Firehole River: 4,500 gallons per minute, or 6 million gallons per day. It is located in Midway Geyser Basin.

Bacteria mats and Grand Prismatic Spring. The orange color is due to bacteria which thrive only on the cooler fringes of the hot spring, while the hotter center of the spring hosts blue-colored bacteria.

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.
