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 Lower Granite Gorge starts on the east side at the start of its due-south excursion around Shivwits Plateau.)
