The known human history of the Grand Canyon area stretches back 10,500 years, when the first evidence of human presence in the area is found. Native Americans have inhabited the Grand Canyon and the area now covered by Grand Canyon National Park for at least the last 4,000 of those years. Ancestral Pueblo peoples, first as the Basketmaker culture and later as the more familiar Pueblo people, developed from the Desert Culture as they became less nomadic and more dependent on agriculture. A similar culture, the Cinchona, also lived in the canyon area. Drought in the late 13th century likely caused both groups to move on. Other people followed, including the Paiute, Cerbat, and the Navajo, only to be later forced onto reservations by the United States Government.

Hualapai Valley is a valley in Mohave County, Arizona.
The Shivwits Plateau is a large plateau in northwest Arizona, and in the northwest of the Grand Canyon region. Just like the Kaibab Plateau in the east Grand Canyon forces the course of the Colorado River encircling it, the Shivwits Plateau is the major course changer of the Colorado in west Grand Canyon. The Colorado River goes due-south on the east perimeter of the plateau, goes west, then northwest to its outfall at Lake Mead. The southwest of the plateau borders the Colorado, but a lower elevation section is directly riverside; it is lower elevation hills and small canyons, called Sanup Plateau, and bordering the section of the Colorado called the Lower Granite Gorge.
The Grand Wash Cliffs extend south-southeast from the Grand Canyon-Parashant National Monument in northwest Arizona west of the Shivwits Plateau south through the Grand Cliffs Wilderness and into the Lake Mead Recreation Area. The Grand Wash Cliffs cross the Grand Canyon where the Colorado River enters Lake Mead. To the south of the Grand Canyon the Grand Wash Cliffs continue past the east side of Grapevine Mesa and then southeast above and east of the Hualapai Valley forming the southwest margin of the Music Mountains.
