Mammoth Hot Springs Guide
Mammoth Hot Springs: A Terraced Landscape of Living Stone Guide
Discover the otherworldly beauty of Mammoth Hot Springs, a unique geothermal area in Yellowstone National Park. Unlike the geysers and hot springs found elsewhere in the park, Mammoth Hot Springs is characterized by its stunning travertine terraces, formed by the deposition of calcium carbonate. These terraces, resembling frozen waterfalls, create a surreal and ever-changing landscape. The hot springs at Mammoth are fed by water heated deep within the Earth. As the hot water rises through limestone formations, it dissolves calcium carbonate. When the water reaches the surface, the carbon dioxide is released, and the calcium carbonate precipitates out, forming the terraces. The colors of the terraces are influenced by thermophiles, similar to the Grand Prismatic Spring, but also by the mineral content of the water. The area has been active for thousands of years, with the terraces constantly growing and changing. Visitors can explore Mammoth Hot Springs via a series of boardwalks and trails. The Upper Terrace Drive offers scenic views of the terraces from the comfort of your car. The boardwalks allow for closer inspection of the formations and provide opportunities to learn about the geology and ecology of the area. Be sure to visit both the Upper and Lower Terraces to experience the full range of features. The Albright Visitor Center, located in the historic Fort Yellowstone, provides information about the park's history and geology.
