The coal field is practically coextensive with the Appalachian Plateau south of the limit of carboniferous rock formations along the Pennsylvania-New York border. Colorado Plateau Resources The Colorado Plateau is a region of multicolored sandstones, shales, and limestones and of high plateaus, deep canyons, and flat-topped mesas, stretching from the Rocky Mountains to the Wasatch Range.
