This volume will help readers read the Yosemite National Park's landscape the way a geologist does. The authors tell the park's history and describe the origins of its hundreds of little known but surprisingly accessible features. They illustrate it all with illuminating color photographs, maps and clear diagrams. Readers will discover things like why many of Yosemite's domes shed rock shells like onion layers, what happens when a volcano erupts under a glacial lake, and why rocks seem to be almost continually tumbling from the region's cliffs.
