5.0 out of 5 stars Roadside Geology of Northern and Central California, April 6, 2000

This review is from: Roadside Geology of Northern and Central California (Paperback)

Once again, David Alt provides a very useful guide to California's roadside geology in this updated and expanded version of his "Roadside Geology of Northern California". It will be especially useful to teachers as a resource for planning lessons and field trips, amateurs who wish to learn more about geology or simply impress their friends, parents with the desire to get their children interested in the subject, and even professional geologists who want to enhance their knowledge.

The book provides a plethora of information for those who wish to see the many interesting and complex geological features of the northern and central areas of California. However, in order to make the best use of this book and fully appreciate the physical and historical geology presented, the reader should have a basic background in geology. This book will even refresh the memories of those folks with a somewhat oxidized recollection of rocks, minerals, geologic structures, and the like.

This book is not aimed at rock hounds, as its emphasis is not on collecting. The educated collector will find it interesting, though.

There are only two "problems" with this book. First, it will lengthen the trips you take as you look for the geologic features it discusses. Second, you may endanger your life as you stop to look at the road cuts discussed in the book or divert your gaze from the road to rocks while driving.

4.0 out of 5 stars Vastly improved update and handy field reference, July 5, 2001

By 

Roger Edwards (Norman, OK United States) - See all my reviews

This review is from: Roadside Geology of Northern and Central California (Paperback)

In 1975, the original "Roadside Geology of Northern California," with the same authors, presented a new way for the amateur rock enthusiast to learn about the complicated geology of northern California. Unfortunately, it was painfully vague, missing important information found in other books of the series, such as significant insight into how formations developed and their ages (e.g., Cretaceous, Devonian, etc.). By in large, this Y2K update solves the problem, and expands the original's spatial coverage southward to San Luis Obispo and the San Joaquin Valley. The improvement in information is phenomenal -- partly because of the increased knowledge gained in 25 years as alluded in the preface, but mostly because of better writing and attention to detail. For example, the Chapter 4 (Coast Range) discussion on how different rock types develop from different areas of ocean sediments may be the best I have ever seen in any forum -- concise (4 pages) and non-technical, yet stuffed with information. Like several other areas of the book, it includes interesting insight into how geologists have handled the difficulties in classifying and sorting California's wild assemblage of rocks; for example: "During the late 1960s, geologists finally accepted that large parts of the Franciscan complex are almost hopelessly scrambled. They agreed to call these chaotic jumbles melanges....Recognition of melanges was, in a way, an admission of defeat." Other chapters contain similar nuggets of "inside" information into the processes of rocks and the way they are studied.

Of course, the foundation of this book, as in the whole series, is in its sequential descriptions and explanations of the rocks one encouters while driving various roadways. The improvement in detail here is vast as well. There are still a few ambiguities in rock age (e.g., Paleozoic/Mesozoic schists of the northern Klamath region...aren't the actual ages more precisely known?). A few typos or fragmented sentences appear to have escaped the proofreaders. But overall, this is a well-composed and thorough look at northern and central California geology for the layman. Residents and vacationers who want to know about the rocks they see must have this book. It has greatly helped me to understand the processes behind rocks I have gathered there.

4.0 out of 5 stars A must-have field reference, August 11, 2002

This review is from: Roadside Geology of Northern and Central California (Paperback)

As an owner of the original 1975 edition, I was both impressed and dissapointed by the scope of this edition. In the expanded text, modern geologic theory is covered in plain-English in a manner that makes this a must-have for any geology student or enthusiast. An incredible amount of information lies within the covers in easy to digest segments.
The new road maps themselves however suffer from trying to cover too many miles in too few pages. Compared to the 1st edition, the geologic "points of interest" are fewer and farther between and many notable geologic features are missed or ignored. (It's almost as if Alt and Hyndman rushed a couple of weekend trips along various highways while dictating notes as they whizzed by obvious rock formations.)
Still, it's an excellent reference that does a credible job of covering a 100,000+ square mile area full of some of the most varied and complex geology on the planet.
Good reading both at home and on the road and perfect by itself for the casually curious. Students, teachers and rockhounds will find it to be a valuable "companion book" to more detailed texts as this volume presents only "the big picture" as viewed from the roadside.
