Straddling the Arizona, Utah, Colorado, and New Mexico state lines, the Colorado Plateau spans a rugged expanse of canyons, desert vistas, and alpine peaks. It’s dry, colorful, and exceptionally rocky, encompassing iconic landscapes like the Grand Canyon, Zion, and Arches, along with millions of acres more of spectacular public lands. The Colorado Plateau holds a rich archaeological record of the Southwest’s earliest people, and it is home to 15 Native American tribes whose cultures, traditions, and teachings continue to infuse the region today.
Think of the Colorado Plateau as a layer cake of rock — sandstones stacked on shales, stacked on mudstones, stacked on sandstones. As geologic forces thrust these rock layers thousands of feet above sea level, they remained relatively unbroken. Then over millions of years, erosion sculpted the landscape into a maze of canyons, mesas, buttes, and a few isolated mountains.
The Escalante River and the Henry Mountains, both on the plateau, were the last river and mountain range to be mapped in the lower 48.
