Mammoth Hot Springs mineral terrace in the Yellowstone National Park,Wyoming,USA. The terraces form at the outflow of geothermal springs. The water is heated under pressure deep underground. This dissolves large amounts of minerals from the surrounding rocks and then deposits them at the surface as it cools. The white material on the terraces is the mineral travertine (calcium carbonate) | |
