Petrified Forest National Park, Arizona
Here in the Late Triassic Chinle Formation are widespread deposits of petrified logs. Some are nearly 2 meters in diameter and 60 meters long (6.5 by 197 feet). Preserved in bright colors of opal and other minerals, the most common trees are relatives of the living monkey puzzle or Hawaiian star pine. Paleontologists believe many of the logs floated to the area in Triassic rivers and became stranded. In the museum are displays of various fossil plant species and animal fossils from the same deposits. Mailing address: P.O. Box 2217, Petrified Forest National Park, AZ 86028.
