Grand Prismatic Spring colored by thermophiles, Yellowstone National Park, 2013.. Hot springs are the most common hydrothermal feature in Yellowstone National Park. Beginning as precipitation, water seeps down through the bedrock under Yellowstone and becomes superheated at depth. An open plumbing system allows that now-hot water to rise back to the surface unimpeded. There is no eruption due to convection currents that keep the water circulating, preventing the extreme pressure and heat required for an eruption. Though it should be noted that at times, fierce, boiling water within a hot spring can explode - similar to a geyser.

Fountain Paint Pot (mudpot), Yellowstone National Park, 2015.. A mudpot is a natural double boiler. First, surface water collects in a shallow, impermeable depression that has no direct contact with underground water. Water beneath the depression causes steam to rise through the ground, heating the collected surface water. Hydrogen sulfide is usually present (which is why they smell like rotten eggs.) Some extremophiles use hydrogen sulfide for energy. These microbes convert the gas to sulfuric acid, breaking down the rock into clay. The result is a gooey mixture of gases and clay. Minerals tint mudpots with such a large palette of colors that mudpots are often called 'paint pots'. Iron oxides cause pinks, beiges and grays of the Fountain Paint Pots.

Brown bear near Swan Lake, Yellowstone National Park, 2015.. Brown bears (Ursus arctos) are the largest terrestrial member of the order carnivoran, which includes 280 species of placental mammals. It is widely-distributed throughout northern Eurasia and North America, though various local populations have shrunk or faced extinction. The total population hovers around 200,000 individuals (as of 2012). The brown bear and American black bear are the only two bears not classified as 'threatened' by the IUCN.
