A fossilized piece of wood in Petrified Forest National Park (Arizona), where hundreds of petrified tree trunks, visible above soil level, can be seen. Iron, manganese, carbon and other minerals have imparted these unusual colors to the silica that was deposited in the wood as it lay buried under mud and water.
