Travertine Pools, Mammoth Hot Springs
This is an active hydrothermal area, which means that the terraces and pools are constantly growing and changing. It starts with water from rain and snow that sinks into the earth and meets a geothermal heat source like a magma chamber. The liquid boils and rises to the surface, mixing with carbon dioxide, which dissolves calcium carbonate from the limestone. The water bursts forth above ground, transplanting the mineral to the surface. As the water cools, it deposits the calcium carbonate in thin layers that build up over time in the form of terraces.
