"A virtual road trip through geologic time that opens ancient windows on how the West was made. Meldahl is the ideal tour guide, blending history and geology to explain the rocks and topography of the American West and how geology shaped its settlement"--David Montgomery, author of Dirt: The Erosion of Civilizations

"The geology of the western United States is as fascinating, yet as enigmatic, as that of any region in the world. Keith Meldahl not only makes it comprehensible, he makes us want to hit the road to see it for ourselves. If you are curious about how our unique American West got to be the way it is, read this engaging book."--James Lawrence Powell, author of Dead Pool and Grand Canyon

"This book is far and away the most readable and geologically informative about the West. A real tour-de-force."--William R. Dickinson, University of Arizona

"Meldahl effectively integrates human history with the much longer, and still active, geologic history."--Eldridge M. Moores, coeditor of Bedrock: Writers on the Wonders of Geology
