California’s Amazing Geology by Don Prothero is an amazing book about — wait for it — California’s geology!
California is one of the most geologically interesting and complex geopolitical units in the world. But so is Minnesota, and Minnesota is boring, geologically, for most people. Why? Because Minnesota is all eroded down and flattened out and covered with glacial till, so most of the interesting geology is buried, while California is actively engaged in its own geology in a spectacular and visually appealing way!
Lots of places have volcanoes. California has volcanoes that blow up, or that have erupted recently enough (geologically speaking) that you can still see the stuff laying all over the place they spewed out. Lots of places have rifting. Hell, one of the most interesting and important rifts in global geological history is right here in Minnesota. But, do people go to Duluth to see that rift, or to see Bob Dylan’s house? The latter, I think. In Califonria, there are three or four different kinds of major tectonic activity, including lots of plate tectonic movement, some spreading, and a big chunk of the amazing Basin and Range extension phenomenon. (That was where what is roughly Nevada and big sections of Utah and California stretched out to several times its original size. In the old days, Reno and Salt Lake Cities wold have been in the same Congressional District!)
California doesn’t’ just have mountains. It has several different kinds of mountains, most of which are currently actively forming right before our very eyes, or so recently formed they still have the tags hanging off them.
California’s Amazing Geology begins with several chapters on basic geology. If you know basic geology you can skip quickly through this and refer back later when you forget something. Then there are several sections each dealing with a different geological region. Then, there is a chapter that literally puts it all together (“Assembling California”). Following this is a compendium of information on California’s main geological resources (gold, oil, water, etc., including fossils!)
There are three things you need to know about this book. First, it covers everything pretty completely, considering the vastness of California and the fact that the book is 480 pages long. Second, it is very up to date. There aren’t any up to date books about California Geology. Third, it is written by Don Prothero, which means that complicated and nuanced scientific topics are explained in a way that a reasonably educated non expert can totally understand. Books like this all too commonly fall into jargonistic language either because the author has no clue it is happening, or because they are written for a highly specialized audience (and maybe the author is even a bit insecure). Don Prothero does not do that. He simply gives you the information in a respectfully, clear, understandable, but not watered down manner. A lot of people will tell you that is not possible. They are wrong, and Prothero does it all the time.
The illustrations, many by Don’s son, are excellent and numerous.

This is a bit of a specialized book unless you frequently visit or live in California. It is suitable as a textbook in college, but also, in just the right California science elective class. If you you are a modern student of natural history and California is in your catchment, this is a must-have book.
I am a little confused about its availability. The publication date is 2017, I got a pre-publication review copy, but it looks like you can actually buy it on Amazon now. But, I’m not sure what happens if you click through, maybe they tell you it will be delivered in January.
