Geological Evolution of the Colorado Plateau of Eastern Utah and Western Colorado

Robert Fillmore’s clear, easy-to-read text documents spectacular features of the eastern Colorado Plateau, one of the most interesting and scenic geologic regions in the world. The area covered in detail stretches from the Book Cliffs to the deep canyons of the San Juan River area. The events that shaped this vast region are clearly described and include the most recent interpretations of ongoing geologic forces. The book also includes mile-by-mile road logs with explanations of the various features for most of the scenic roads in the region, including Arches National Park, Canyonlands National Park, and the Natural Bridges area.

Robert Fillmore is professor of geology at Western State College of Colorado in Gunnison. He is the author of Geology of the Parks, Monuments, and Wildlands of Southern Utah.
