Mammoth Hot Springs, Thermal terraces in Yellowstone National Park, Wyoming, United States.
These calcium carbonate formations create white limestone steps filled with mineral-rich water at temperatures reaching 165 degrees Fahrenheit.
Fort Yellowstone, established in 1886, served as the U.S. Army headquarters to protect the park from vandalism and poaching until 1918.
Native American tribes including Blackfeet, Crow, and Shoshone considered these springs sacred grounds for healing and ceremonial gatherings.
Visitors can access two miles of elevated boardwalks throughout the terrace complex, providing safe viewing points of the thermal features.
The springs deposit about two tons of travertine limestone each day, continuously reshaping the terraces and creating new mineral formations.
