Best known for globally significant Late Triassic fossils, Petrified Forest National Park was designated a national monument in 1906 to preserve and protect the petrified wood for its scientific value. Scientific studies are on-going at the park; paleontologists find new fossils, biologists study living plants and animals, and geologists study the multi-hued Chinle Formation.
Petrified Forest National Park doesn't allow camping, though backpacking is permitted and there are plenty of campgrounds just outside the park. A world of science is waiting to be discovered.
