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.

The Geomorphic Evolution of the Yosemite Valley and Sierra Nevada Landscapes
A very, very, detailed exposition of the evidence and reasoning behind Mr. Schaffer's theories on the geomorphology of glacial valleys, theories that put him severely at odds with the accepted 'wisdom.' Written for the dedicated amateur geologist. I learned a lot about geology and a good bit about the importance of received wisdom in the scientific process.
The author is not always clear in where he is going conceptually with his evidence and arguments despite extensive initial argumentation but he admits that he is mixing argument with extremely detail field observations.
I greatly appreciated having read this book.
