Death Valley

This used to be a submerged lake about 23 million years ago, when ancient horizontal layers of sediment and rock were pushed and folded by the movement of the earth's crust, lifting the Andes mountain range and leaving some layers in a vertical position. It has been shaped throughout time by wind and rain, giving rise to spectacular natural sculptures of various colours due to the minerals here, mainly salt, gypsum and clay.
