Colorado Plateau of eastern and southern Utah, and northern Arizona
The Colorado Plateau is a geographic area roughly located on the Four Corners region of four states: northern Arizona, southern and eastern Utah, western Colorado and northwestern New Mexico. Most of the Plateau is drained by the Colorado River. Ten national parks and seventeen national monuments are within its boundaries. Red Rock Country is a descriptive nickname because of the bright colored rocks sculpted by erosion from water and wind. The crown jewel of the area is the Grand Canyon National Park in northern Arizona.
