Petrified Forest National Park (Arizona). This portion of the Chinle Formation has a great concentration of 225-million-year-old petrified wood. The surrounding region, the Painted Desert, has eroded red-hued volcanic rock called bentonite. There are also dinosaur fossils and over 350 Native American sites.
One of the world's largest and most colorful concentrations of petrified wood is found in Arizona's Petrified Forest National Park.

I remember that my parents purchased a beautiful set of bookends made from polished petrified wood - I wonder what ever happened to them?
