Mammoth Hot Springs in Yellowstone National Park is just 5 miles south of the North Entrance at Gardiner Montana.
The area has a rich history and was the first outpost established by the U.S. Army in 1886 to help protect Yellowstone.
The Mammoth Hot Springs area sits on a bed of limestone which gives the terraces their white colouring. The natural landscapes at Mammoth are some of the most dynamic in the park and many of the features here can change on a daily basis.
Hot water rising to the surface creates chemical reactions that dissolve and transform the limestone, depositing calcium carbonate in the form of travertine on the surface of the terraces.
Microorganisms known as thermophiles that survive in these extreme temperatures create the unique colour palettes associated with the hot springs at Mammoth.
