The Grand Prismatic Spring in Yellowstone National Park is the largest hot spring in the United States, and the third largest in the world. (diameter is 380 feet) So for this shot I needed to pull out the fish eye 11mm-24mm lens. The iridescent colors are caused by bands of microbes that thrive in these warm to hot waters. The calothrix cyanobacteria lives in temperatures of no less than 30 degrees Celsius and produces the brown color that frames the spring. Phormidium, meanwhile, prefers a 45-60-degree-Celsius and creates the orange pigment, while synechococcus enjoys temperatures of up to 72 degrees Celsius and is yellow-green. The deep blue colour seen in the centre is the natural colour of the water which is too hot for most bacteria.
