Looking north at the painted desert, the red, gray, and blue mud and sandstone of the Chinle formation forms a series of beautiful but forbidding badlands. On a clear day, the Jurassic and Cretaceous age rock units of the Navajo and Hopi lands would be visible in the distance.

The Chinle is rich in fossils. Not only trees, but fossil vertebrates, invertebrates, and smaller plants from this unit make the Chinle an especially informative source of information of life in the Late Triassic.
