The Ozark s, also referred to as the Ozark Mountains and Ozark Plateau, is a physiographic region in the U.S. states of Arkansas, Missouri, Oklahoma, and Kansas.

A large plateau in North America is the Colorado Plateau, which covers about 337,000 km2 (130,000 sq mi) in Colorado, Utah, Arizona and New Mexico. In northern Arizona and southern Utah the Colorado Plateau is bisected by the Colorado River and the Grand Canyon. How this came to be is that over 10 million years ago, a river was already there, though not necessarily on exactly the same course.
