Ancient Landscapes of the Colorado Plateau by Ron Blakey & Wayne Ranney

Over the winter break, I read the new book Ancient Landscapes of the Colorado Plateau, by Ron Blakey & Wayne Ranney. This is an excellent read, and a terrific introduction to the geologic history of one the world's most dramatic landscapes. Blakey's maps have been featured on this blog before, and he has been kind enough to allow me to modify some for use on my field course websites (like here and here and here). The book goes through geologic time and makes extensive use of beautiful paleogeographic maps to reveal the story of mountain-building, transgression, regression, sand-dunes, faulting, volcanism, and erosion that characterizes the Colorado Plateau. It's not just paleogeographic maps, by the way: there are also plenty of shots of fossils, Colorado Plateau landscapes, and comparable modern depositional environments to enliven the story. It's a graphic story, well told with excellent graphics. I recommend you get yourself a copy if you've ever been to the Colorado Plateau, or if you ever plan on going there.

Find the book: On Amazon ... At the NOVA library
