This is Cerro de los Siete Colores, the Hill of Seven Colors in English. You'll find it in the Andes, in Argentina's Jujuy province. Tectonic movement revealed the earth's many layers of sediment and their amazing colors. The dark brown is rich in manganese and is about two million years old. The red layer is a mixture of red clay and sand laid down three to four million years ago. The brown and purple layers are around 90 million years ago and are colored by the ratio of lead and calcium carbonate. The yellow is also from that period, with a layer heavy in sulphur. The white layer is limestone, at least 400 million years old.
The legend of the hill is that the children of the village of Purmamarca at its base decided to paint the hill one day, and snuck away for seven nights to leave it as you see it today. Read more about Cerro de los Siete Colores and see more gorgeous pictures at Kuriositas.
