Petrified Forest National Park in north eastern Arizona, between Gallup and Holbrook, features one of the world's largest and most colourful concentrations of petrified wood. Also included in the Park's 93,533 acres are the multi-hued badlands of the Painted Desert, archeological sites and displays of 225 million-year-old fossils.

Ranger talks and tours are scheduled most of the year and March is set aside for Archeology Month.
