Geothermal pools in Biscuit Basin, Yellowstone Park. Wyoming, USA
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.

The aquamarine colors of this Yellowstone hot spring are reflections of bacteria that thrive in the hottest waters of the park.
Old Faithful Geyser is one of the most famous geysers in the world, known for its regular eruptions. It was named in 1870 for its reliability in spewing hot water and steam at intervals of 60 to 110 minutes, reaching heights of 100 to 180 feet. Each eruption lasts about 1.5 to 5 minutes, discharging up to 8,400 gallons of water. Old Faithful is fueled by geothermal activity from the Yellowstone Caldera, a supervolcano, and has erupted more than a million times since the park's founding.

Old Faithful Geyser Eruption, Wonderful natural landscape. Yellowstone National Park is famous for its rich wildlife species and geothermal resources.
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.
