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. Photo: © NPS
