West Thumb Colors
Hot water pours into Yellowstone Lake from one of the main drainages of the West Thumb Geyser Basin, colorful bacteria and minerals staining the underlying beach in ochre tones. A band of thunderstorms had moved through rather rapidly within the preceding hour, and by this time already passed the Absaroka Mountains in the distance, leaving behind a clean, chaotic and beautiful sky.
