Geology Underfoot in Yosemite National Park

Few places in the nation rival Yosemite National Park for vertigo-inducing cliffs, plunging waterfalls, and stunning panoramic views of granite peaks. Many of the features that visitors find most tantalizing about Yosemite have unique and compelling geologic storiestales that continue to unfold today in vivid, often destructive ways. While visiting these more than twenty-seven amazing sites, you'll discover 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. With a multitude of colorful photos and illustrations, and prose tooled for the lay reader, Geology Underfoot in Yosemite National Park will help you read the landscape the way a geologist does.

Allen Glazner is the Kenan Distinguished Professor of Geological Sciences at the University of North Carolina at Chapel Hill. A native Californian, he holds a PhD from the University of California at Los Angeles and has done research in the Sierra Nevada and Mojave Desert since his undergraduate days at Pomona College.Greg Stock was born and raised in the Sierra Nevada just north of Yosemite, and he has explored the region by climbing on and caving in the region's unique geology. These interests led him to pursue a bachelor's degree in geology at Humboldt State University and a PhD in earth science at the University of California at Santa Cruz, where he studied the uplift and erosion of the Sierra Nevada. Greg is presently Yosemite National Park's first-ever park geologist. He lives in Yosemite Valley with his wife, Sarah, and daughter, Autumn.
