Where - boundaries

You can draw the boundaries of the Colorado Plateau based on geology, box it by the Colorado River Basin, or delineate it by climate and precipitation. Among Colorado Plateau afficionados, determining its boundaries can turn into a heated debate.

Here at the Trust, we use natural features to bound our area of work — the Uinta Mountains to the north, the Rocky Mountains to the east, the Mogollon Rim to the South, and the Basin and Range province to the west — with most of our work focused in northern Arizona and southern Utah.

Where - CO plateau geology

Geologically speaking

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.
