The province covers an area of 337,000 km (130,000 mi) within western Colorado, northwestern New Mexico, southern and eastern Utah, and northern Arizona . About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado . Most of the remainder of the plateau is drained by the Rio Grande and its tributaries . </P> <P> The Colorado Plateau is largely made up of high desert, with scattered areas of forests . In the southwest corner of the Colorado Plateau lies the Grand Canyon of the Colorado River . Much of the Plateau's landscape is related, in both appearance and geologic history, to the Grand Canyon . The nickname "Red Rock Country" suggests the brightly colored rock left bare to the view by dryness and erosion . Domes, hoodoos, fins, reefs, river narrows, natural bridges, and slot canyons are only some of the additional features typical of the Plateau . </P>
