[close] As an explainer, John McPhee is a national treasure. The longtime "New Yorker" staff writer has taken us inside the world of art museums, environmental groups, fruit markets, airship factories, basketball courts, and atomic-bomb labs the world over. Here he covers the complex geological history of California, the source of much news today. As Californians daily await the inevitable great earthquake that will send their cities tumbling down like so many matchsticks, McPhee piles fact on luminous fact, wrestling raw data into a beautifully written narrative that gainsays a sedimentologist's warning: "You can't cope with this in an organized way," he told McPhee, "because the rocks aren't organized." As always, McPhee enlarges our understanding of the strange, making it familiar--and endlessly interesting. [close]
