Only one national park in the country includes and protects a section of historic Route 66: the Petrified Forest National Park with one of the world’s largest and most colorful concentrations of petrified wood, multi-hued badlands of the Painted Desert, historic structures, archeological sites, and displays of over 200-million-year-old fossils.
Giant Logs is part of Rainbow Forest in Petrified Forest National Park. Once an ancient log jam in a Late Triassic river, Giant Logs was the heart of the original national monument set aside in 1906 by President Theodore Roosevelt.
