Steamboat Geyser in Norris Basin in Yellowstone park, WYO, USA.
Yellowstone National Park, Wyoming, United States: The runoff from Grand Prismatic Spring in Yellowstone National Park carries mineral-rich, hot water from the spring’s center into surrounding channels where it gradually cools. As the temperature decreases, distinct microbial communities thrive, forming vivid bands of color ranging from orange and red to green. These thermophilic bacteria and archaea metabolize differently depending on temperature and light, creating the characteristic gradients visible around the spring. The runoff contributes to the hydrothermal ecosystem of the Midway Geyser Basin, illustrating the link between geothermal activity, chemistry, and microbial life.
