Mammoth Hot Springs Panorama, Yellowstone, Wyoming Poster

"Mammoth Hot Springs Panorama, Yellowstone National Park, Wyoming" by Catherine Sherman. Mammoth Hot Springs shines white against the hillside in the view looking from the west in Yellowstone National Park, Wyoming. Mammoth Hot Springs is a large complex of hot springs on a hill of travertine in Yellowstone National Park adjacent to Fort Yellowstone and the Mammoth Hot Springs Historic District. It was created over thousands of years as hot water from the spring cooled and deposited calcium carbonate (over two tons flow into Mammoth each day in a solution). Although these springs lie outside the caldera boundary, their energy has been attributed to the same magmatic system that fuels other Yellowstone geothermal areas.
