The gold-colored runoff at the Upper Geyser Basin in Yellowstone National Park is typically caused by thermophiles, heat-loving microorganisms that thrive in the hot, mineral-rich waters of the geothermal features. These microorganisms, particularly certain types of bacteria and archaea, produce pigments that give the runoff its striking colors. The gold or yellow color is often attributed to thermophilic bacteria like Thermocrinis or other species that can process sulfur or iron, creating vibrant hues in the runoff channels. These colorful runoffs are a hallmark of the park's geothermal activity.
