Petrified Forest is best known for its ancient trees that have crystallized over 225 million years into rainbow colors. The park also features fossils from huge 18-foot crocodile-like creatures known as Phytosaurs, as well as remnants from 13,000 years of human history, including the remains of villages, tools, and grinding stones. A 28-mile road runs through the park, offering a number of short hiking trails into the diverse landscape of wild grasslands and Painted Desert vistas and colorful badlands.
