The orange bacterial mats at Upper Geyser Basin in Yellowstone National Park are created by thermophilic cyanobacteria, which thrive in the hot, mineral-rich waters flowing from geysers and hot springs. The vibrant orange color comes from pigments these bacteria produce to photosynthesize in extreme heat, typically between 104°F and 167°F. As the water cools, different species create a gradient of colors, showcasing the adaptability of these extremophiles in Yellowstone's harsh geothermal environment.
