Query: Who Knew California Came From Central America?

Very readable book, despite the complexity of the topic. Not as simplified as McPhee, but fascinating enough I got through the science. My particular interest was where the little slip of California that is Pacific Plate came from--Central America? Some ocean island? I found lots of hints in this book, though as with everything that is pre-historic, it's impossible to say for sure. Overall, if you read this book because of an interest in geology, you'll enjoy the ride.
