| Carving Grand Canyon:
Evidence, Theories and Mystery
Fourth Printing!
Best Arizona Science Book - 2007

The Grand Canyon is one of earth's most recognizable landscapes, yet a definitive answer for how or when it formed has proved elusive — even though geologists have studied the canyon for almost 150 years! The one thing that scientists do agree upon is that the Grand Canyon was carved by the erosive power of the Colorado River. This is known even though the river itself has carried away the evidence for its earliest history.
This is the first book in almost five decades that explains in layman's terms the possible sequence of events that may have given rise to this stupendous landscape. The text reads like a good mystery novel, as well it should since there is much intrigue and many unknowns concerning the canyon's history. Readers will find chapters on how rivers actually carve canyons, a listing and discussion of the various theories that have been proposed through the years (and the geologists who developed them), and a plausible sequence of events that created the canyon landscape of today.
The book is filled with color photographs by the author as well as other well-known southwestern photographers, paintings by Grand Canyon artist Bruce Aiken, numerous original illustrations and maps, and views of the canyon from space. A concise summary of the most likely set of events that gave rise to Grand Canyon is included at the end of the book. A glossary, index, and scientific and popular bibliographies are included.

The Verde Valley: A Geological History
Volcanoes erupting on a primeval ocean floor, tropical coral seas, sand dunes blowing along the coastline of an ancient supercontinent...these are some of the colorful scenes that geologists have reconstructed from the rocks contained within the Verde Valley. The oldest rocks, exposed near Jerome, are about 1.82 billion years old, when the Verde Valley was unrecognizable as we know it today. Published in 1989, this is Volume 60, Number 3 in the Museum of Northern Arizona's Plateau series. $7.00 [How to order] |

Sedona Through Time: Geology of the Red Rocks
Visitors to the towering red rock spires of Sedona seldom suspect that the area was once a broad river floodplain that lay beyond the Ancestral Rocky Mountains. This same place was later buried in a vast, Sahara-like desert, still later to lie beneath the waters of a warm tropical sea filled with ancient life forms. Sedona Through Time is an eminently readable story of the evolution of this fantastic landscape through the eons of geologic time. $14.95. [How to order] |
