Located at Mammoth Hot Springs in Yellowstone National Park, USA, it is the world’s largest known carbonate-deposit hot spring. Millions of years ago, seawater at the bottom of the Mammoth region left behind thick layers of precipitated limestone. Whenever hot, acidic water flows through the rock layers to the surface of the hot springs, it dissolves large amounts of this precipitated limestone. Upon exposure to air, some of the carbon dioxide in the solution evaporates. At the same time, solid minerals form and eventually settle as pristine travertine, giving the Mammoth Hot Springs area vast terraces that look as if they’re coated in frosting. This unique landscape has also earned Mammoth Hot Springs a spot among the world’s most captivating hot springs.

Hot water gushes from limestone layers, dissolving calcium carbonate in the process. As the water reaches the surface and cools, the calcium carbonate becomes oversaturated and precipitates, forming step-like travertine platforms.

When underground outlets are blocked by sediment, the spring water diverts to other exits, forming new platforms. From a distance, these look like glittering mounds of gold and jade, with their beautiful, irregular patterns created by the activity of algae and microorganisms in the deposited spring water. These organisms produce hues of yellow, white, and brown, layer upon layer, resulting in a dreamlike, multicolored terrace reminiscent of rice paddies.
