Mammoth Hot Springs - Travertine Terraces and Parade Ground
Yellowstone is a place of change, and this view highlights a place where change is constant and evident—the travertine terraces of Mammoth Hot Springs. Terraces form when water rises through limestone, which then allows the water to carry high amounts of dissolved calcium carbonate. At the surface, carbon dioxide is released and the calcium carbonate is deposited, forming travertine, the chalky white rock of the terraces. In the foreground are the parade grounds for historic Fort Yellowstone—the focal point of daily life at the fort.
