Mammoth Hot Springs tourists boardwalk from Upper Terrace 4K. Mammoth Hot Springs is a large complex of hot geyser springs and pools on a hill of travertine in Yellowstone National Park near Fort Yellowstone and the Mammoth Hot Springs Historic District. The most famous feature at the springs is the Minerva Terrace a series of travertine terraces. Due to recent minor earthquake activity the spring vent has shifted rendering the terraces mostly dry. The War Department in August 1886 sent a company of cavalry to Mammoth Hot Springs to build a cavalry post. U.S. Army management of Yellowstone was so successful that by 1891 they were also managing Sequoia Yosemite and Kings Canyon National Parks in California. Tourist from throughout the world come to Yellowstone. At least 3 million tourists have visited the park almost every year. 4K UHD HD video footage. Don Despain of Rekindle Photo.
