Arizona is home to the Petrified Forest National Park.

Petrified Forest National Park, located in northeastern Arizona, is famous for its stunning collection of fossilized trees, some of which are over 200 million years old. The park is known for its colorful and well-preserved petrified wood, along with its beautiful desert landscapes. In addition to the petrified wood, the park features significant archaeological sites and ancient petroglyphs, making it a fascinating destination for both geology and history enthusiasts.
