Yellowstone National Park, Wyoming, USA: the travertine pools of Palette Spring in Mammoth Hot Springs, Yellowstone National Park, are formed by hot, calcium-rich water emerging from underground sources. As the water cools and releases carbon dioxide at the surface, calcium carbonate precipitates, building terraces and rimstone pools. These pools display striking colors—white, yellow, and orange—caused by thermophilic microorganisms and mineral deposits. Constant fluctuations in water flow, temperature, and chemistry reshape the formations over time.
