Petrified logs scattered about a vast pink-hued lunarlike landscape resemble a fairy-tale forest turned to stone at Petrified Forest National Park. The park's 218,533 acres, which include portions of the Painted Desert, are covered with petrified tree trunks whose wood cells were fossilized over centuries by brightly hued mineral deposits—silica, iron oxide, carbon, manganese, aluminum, copper, and lithium. The park holds plenty of other fossils; remnants of humans and their artifacts have been recovered at more than 500 sites in the park.
- Terrific timber Be mesmerized by the clusters of petrified (fossilized) wood. The trees look like they're made of colorful stone.
- Walls with words Don't scratch the surface, but see how others did. Ancestors of the Hopi, Zuni, and Navajo left their mark in petroglyphs cut, scratched, or carved into stone.
- Route 66 kicks A section of the fabled road is preserved in the park, the only section of the highway protected in a national park.
- Triassic treasures Find an oasis of water in the desert, or at least evidence that it once existed. Clam fossils in the park indicate that waterways once prevailed where sand, stone, and trees now define the land.
- Corps creations The Painted Desert Inn, a National Historic Landmark, was modernized by the Civilian Conservation Corps (CCC) during the throes of the Great Depression. It is now a museum and bookstore.
