Sedona Through Time

Sedona Through Time (3rd edition), by Wayne Ranney, is the third book in what I like to call Ranney's Rock Trilogy. Book One, Ancient Landscapes Of The Colorado Plateau (co-written with Ron Blakey), takes us step-by-step through the landscape changes in the Four Corners area, beautifully illustrating each geologic occurrence with Paleogeographic maps. Book Two, Carving Grand Canyon, zooms in on the most breathtaking landform in North America, delving into a lesser-known feature called the Mogollon Highlands, which turns out to be one of the major forces in the formation of the Grand Canyon and of Sedona, the focus of Book Three.

By the time you read Sedona Through Time, you've got a much better idea of how the layers in Sedona formed, because they are many of the same layers present in the Grand Canyon. But once you go Southeast to Sedona, those layers have changed a bit in character, and some unique features appear, like the Schnebly Hill Formation. The helpful diagrams, maps, and photographs that are present in Books One & Two of Ranney's Rock Trilogy are also present in Book Three, and they are very effective in illustrating the geologic events that created Sedona.

Anyone who visits Sedona and nearby Oak Creek Canyon is struck by their beauty and serenity. They possess a profound spirit that is as beautiful as what you can experience in the Grand Canyon, but is much more up-close and personal. Having some knowledge of what the rocks are and how they got there enhances that experience. For visitors whose curiosity is piqued, the book also includes a point-by-point road and trail guide. So take it with you when you visit – you'll see Sedona and Oak Creek Canyon as you've never seen them before.
