Ages of the Navajo Sandstone

The real Jurassic Park was as an ancient landscape home to a vast desert covered mostly in sand dunes as far as the eye could see, where dinosaurs and small mammals roamed southern Utah. The Navajo Sandstone is known for its beautiful red and tan crossbedded sandstones that grace many of the national parks and monuments in the southwest USA — for example Arches, Canyonlands, Capitol Reef, and Zion national parks.
