Overview

This book provides a new interpretation of the formation of Yosemite Valley and the entire Sierra Nevada range. Whereas previous interpretations said that the Sierra Nevada was a relatively young mountain range and that most of its deep valleys were carved by glaciers, this new view indicates that the Sierra is an old range and that most of the canyons and valleys owe their existence to mass wasting, or "rockfall." Contrary to what most of us learned as the truth about the formation of the Sierra, Schaffer presents evidence that glaciers performed very little erosion.

Jeff Schaffer is a naturalist and Yosemite climber who started exploring the Sierra Nevada in 1962. He has hiked more miles and explored more Sierran terrain than any other past or present naturalist or geologist, including John Muir and François Matthes.

Editorial Reviews

Booknews
Reads (& looks) like a monograph of the American Geologic Society, but is published by a hiking-climbing house. It is an inviting work with illuminating photos and a text that, in part, presents Schaffer's revision of standard geomorphology. Annotation c. by Book News, Inc., Portland, Or.
