    Introduction

    The Colorado Plateau encompasses some of the most scenic regions on Earth. This scenery exposes magnificent outcrops of sedimentary, igneous, and metamorphic rock across the states of Arizona, Colorado, New Mexico, and Utah. Perhaps most spectacular are outcrops of colorful, flat-lying sedimentary rock, especially Permian, Triassic, and Jurassic redbed and eolian deposits that form the centerpieces of the greatest concentration of Parklands in the World.
