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.

Lower Geyser Basin, Yellowstone National Park, Wyoming USA: shallow thermal pool characterized by orange-brown streamers formed by thermophilic microbial mats. These mats consist of heat-loving bacteria and archaea that thrive in the hot, mineral-rich runoff from nearby springs and geysers. As the water cools outward from the vent, different microbial species dominate according to temperature and chemical conditions, producing distinct colors. The filamentous structures visible are colonies of microorganisms that trap fine mineral particles, gradually building textured deposits. This phenomenon illustrates the interplay between geothermal energy, mineral precipitation, and microbial life in Yellowstone’s hydrothermal ecosystem.
