The Petrified Forest National Park, the desert area containing plant and animal fossils and archaeological sites, is located in the eastern part of the state of Arizona. It is 19 miles (30 km) east of Holbrook, Arizona. It was established as a national monument in 1906 and as a national park in 1962. The area within the park proper is 146 square miles (378 square km), but, since 2005, additional land parcels have been acquired and placed under park administration. Today, the entire protected area in the park totals 346 square miles (896 square km).

The park features extensive exhibits of petrified wood in several “forest” areas, which are the remains of ancient tropical groves. Some animal fossils have also been found, including those of dinosaurs and phytosaurs that date to the Triassic Period (252 to 201 million years ago). The park’s archaeological features are petroglyphs (e.g., Newspaper Rock). The Petrified Forest indeed has many features; it makes for a very great vacation.
