This Petrified Wood is found in the Chinle Formation and comes from the Triassic Period around 220 million years ago.
The "Petrified Forest" was made a National Park in 1962. In 1988 the Arizona state legislature designated petrified wood the Arizona state fossil.
Petrified Wood formed when a tree died and is quickly buried by sediments. Minerals in the groundwater then permeated the wood, replacing the original organic matter and turning it to stone. The main mineral is silica, but trace elements in the silica create a variety of colors.
