Located in northeastern Arizona, Petrified Forest National Park is a park about the span of time. Within its 221,391 acres area, it contains surreal landscape famous for its expansive deposits of petrified wood and the vibrant, eroded badlands of the Painted Desert. The high-desert environment preserves a remarkable record of the Late Triassic Epoch, featuring 225-million-year-old fossils of fallen trees that have been transformed over eons into solid quartz and colorful minerals embedded in the Chinle Formation. Beyond its geological wonders, the park is home to over 1,200 archeological sites, including Puerco Pueblo and ancient petroglyphs, which tell the story of human inhabitants spanning more than 13,000 years. More recent in time is the historic US Route 66, which the park preserves a small section.
