Wonders of Nature
Red mountains, AKA rainbow mountains are located in Zhangye Danxia Landform Geological Park. The Rainbow Mountains are cretaceous sandstones and siltstones that were deposited in China before the Himalayan Mountains were formed. The sand and silt was deposited with iron and trace minerals that provided it with the key ingredient to form the colors we see today.
