Bacteria

At Yellowstone Hot Springs

 

Bacteria and other thermophiles (heat loving microorganisms) usually form the ribbons of color you see here. The green, brown, and orange mats are cyanobacteria, which can live in waters as hot as 167 F (73 C). At this temperature they are usually yellow-green. They become orange, rust, or brown as the water cools.
