Painted Desert. Hiker walking through part of the Painted Desert in Petrified Forest National Park,Arizona,USA. This badlands landscape was produced by erosion of the soft sedimentary rock,which consists mainly of sandstone,mud and volcanic ash. Mineral deposits colour the rock. Petrified remains of trees are visible,created when fallen trees became covered in sediment,slowing their natural decay process. Over millions of years,silica deposited from groundwater replaced their tissues,creating perfect mineral replicas | |
