At the eastern margin of the Canyon Lands is the Mesa Verde, a huge cuesta that has been deeply dissected by streams. Here in great recesses in the canyon walls are found the ruins of ancient cliff dwellings. East of the Little Colorado River are the brilliantly colored areas known as the Painted Desert.

Even though it is not the deepest canyon in the world (Kali Gandaki Gorge in Nepal is much deeper [16]), the Grand Canyon is known for its visually overwhelming size and its intricate and colorful landscape. Geologically, it is significant because of the thick sequence of ancient rocks that are well preserved and exposed in the walls of the canyon.

Sandstone exposed in canyons nearer to the Colorado River is typically from the Glen Canyon Group. The dark red cliffs of Coyote Gulch, for example, are composed of Navajo Sandstone.
