Stratigraphy, Sedimentology, Geologic History of Colorado Plateau

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. Explore the various topics below:

The following material is a collection of technical data from my research activities including isopach and facies maps, stratigraphic cross sections, paleogeographic maps, outcrop photos, and references. Most of the material has been published although many of the graphics here are in a more artistic and colorful format than those previously published. See my list of publications for reference citations.
