Great American Desert
From Wikipedia, the free encyclopedia.

The Great American Desert is a somewhat archaic term that describes the area west of the Missouri River and east of the Rocky Mountains. A more modern definition of the term describes the arid region of the Southwest, which includes parts of northern Mexico and the four deserts of North America.
