Sedimentary Rocks on the Colorado Plateau
The Colorado Plateau is one of the World's great show places for sedimentary rocks. Precambrian and all Phanerozoic periods except Ordovician and Silurian are represented. Especially well exposed are Permian through Jurassic sedimentary rocks that were deposited in mostly tropical desert sedimentary environments. These sedimentary rocks provide the focal point for the greatest concentration of National Parks in the World. The Grand Staircase, the southwestern escarpment of the Colorado Plateau, exposes one of the finest and most complete sedimentary sections anywhere!Studies on the Plateau involve numerous NAU Geology faculty and their students. Hundreds of publications and dozens of MS theses have resulted from these studies.

Global Plate Tectonics and Paleogeography
Paleogeography and Geologic History of North America
These maps centered on North America are arranged into 41 time slices from Late Precambrian to Present. During times when Africa and Europe are close to North America, their history is also shown. This is a stand-alone presentation and is not linked to other parts of this web page. (NEW FOR 2005)
Detailed global paleogeography
These large globes are arranged into 27 time slices from Late Precambrian to Present and are presented in spherical, rectangular, and mollewide projections. This is a stand-alone presentation and is not linked to other parts of this web page.

My Research Activities
Presented here 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.Middle Jurassic Page Sandstone
