Mammoth Hot Springs in Yellowstone National Park features stunning travertine terraces formed by geothermal activity and dissolved limestone. Powered by underground volcanic heat, mineral-rich water deposits calcium carbonate as it cools, creating the constantly changing formations. Divided into Upper and Lower Terraces, highlights include Minerva Terrace and Liberty Cap, with vivid colors from heat-loving microorganisms. Located near the park’s headquarters and the Mammoth Hot Springs Hotel, the area is accessible via boardwalks and is home to abundant wildlife. Unique among Yellowstone’s geothermal features, it showcases nature’s artistry in a dynamic and ever-evolving form.
