Travertine Terraces are seen at Mammoth Hot Springs in the northwest corner of Yellowstone National Park, Wyoming. Travertine is a form of calcium carbonate that is dissolved from limestone beneath the ground, and is then carried to the surface by hot water. The colours represent a variety of bacterial algae that survive at various temperatures.
침전물로 된 테라스들이 옐로우국립공원의 북동쪽에 있는 Mamth Hot Spring에 있다. 침전물은 땅속 석회암이 녹아서 만들어진 칼슘 탄산염의 형태이다. 지금은 온천수에 의하여 지표로 올라온 것이다. 색이 다양한 것은 다양한 온도에서도 살아남는 박테리아조류의 색 때문이다.
