Geologic History of Western North America with Paleogeographic Maps
This comprehensive geology book transports readers through deep geologic time, revealing when volcanic islands stretched from Mexico to Alaska and terranes drifted across the Pacific to dock on Western America's shores. The paleogeographic maps provide satellite-like views of ancient Earth, showing how landscapes were transposed thousands of kilometers along massive fault systems.
Award-Winning Geological Research
Winner of the 2021 John D. Haun Landmark Publication Award from AAPG-Rocky Mountain Section, this volume presents complex geologic history through detailed maps and scientific analysis. Each map represents 40-80+ hours of work, constructed from geological literature to accurately depict ancient Earth conditions.
Expert Authorship
Ron Blakey taught geology for over 37 years at Northern Arizona University, specializing in sedimentary rocks of the Colorado Plateau and Pacific Coast region. He has published over 50 papers in national and international journals and constructed paleogeographic maps for 25+ years. His maps appear in geological papers, books, museums, and educational materials worldwide.
Wayne Ranney has studied American West geology since 1975, beginning as a backcountry ranger at the Grand Canyon. He holds bachelor's and master's degrees in geology from Northern Arizona University and has completed over one hundred expeditions to the Arctic, Amazon, Africa, Siberia, and Antarctica as a shipboard geology interpreter. Currently a geology lecturer for Smithsonian Journeys and retired adjunct faculty member, he is an award-winning author of multiple geology books including Sedona Through Time, Carving Grand Canyon, and Ancient Landscapes of the Colorado Plateau.
Comprehensive Coverage of Western North America
The text unfolds the region's complex geologic history, explaining volcanic activity, terrane movement, and tectonic processes that shaped the modern landscape. Readers explore sedimentary rocks, fault systems, and the Pacific Rim's geological development through scientifically accurate reconstructions.
Educational Reference for Geology Students and Professionals
This hardcover volume serves as an essential resource for understanding Western USA geological formations, tectonic plate movements, and volcanic history. The combination of detailed paleogeographic maps and scientific text makes complex geological concepts accessible for academic study and professional reference.

About the AuthorRon Blakey taught geology for over 37 years at the university level, mostly at NAU in Flagstaff, AZ. His specialty is the sedimentary rocks of the Colorado Plateau and surrounding areas including the Pacific Coast region. He has published well over 50 papers, many as single author, in national and international journals and symposia and two books, one published by Springer (see below). For the last 25 years, he has constructed paleogeographic maps from regional to global scale - these maps appear in many published geological papers, books, monographs, museums, and are used extensively in general education at all levels. His maps are based on the geological literature and are constructed as accurately as possible to mimic satellite views of ancient Earth. Many individual maps represent 40 - 80 or more hours of work each.
Wayne Ranney has been studying the geology of the American West since coming to live in Arizona in 1975. His first residence was at the bottom of the Grand Canyon where he worked as a backcountry ranger. He claims this is where he got all of the rocks in his head. In 1978 he enrolled in the geology program at Northern Arizona University, obtaining bachelor's and master's degrees. It was here that took classes from his colleague Dr. Ron Blakey while working his way through graduate school as a river guide. He began working as a shipboard geology interpreter in 1989 and has traveled the world ever since, completing over one hundred expeditions to the Arctic, the Amazon, Africa, Siberia, and Antarctica. These far-flung adventures have allowed him to see and learn about many different kinds of landscapes but he always returns to the red rock cliffs and canyon country of his native southwest. Wayne currently works as a geology lecturer for Smithsonian Journeys and is a retired adjunct faculty member of Yavapai and Coconino colleges. He is an award-winning author of many books including Sedona Through Time, Carving Grand Canyon, and Ancient Landscapes of the Colorado Plateau. He lives with his wife Helen in Flagstaff, Arizona.
