Rocks and Minerals of California

Rating:
Summary: Review by a professional geologist
Review: Good luck on finding mineral sites using this guide. While the minerals may be in the areas indicated, the maps are so crude that the likelihood of your finding the sites is very poor. I have tried using the guide for several years with almost no success.

Summary: Rocks and Minerals of California
Review: Well worth what I paid for it. This book has lots of information and would make a good reference for the Geology of California.

The maps though, don't say what the major highways/roads are, so you'll need another map. I have the book Roadside Geology of North/Central California, and this book goes really well with it.

In some ways, Rocks and Minerals of California I think is more useful, despite the missing road ID. The book has sections of counties (not all but most) and minerals found in those areas. Also, quadrangle information, township/range locations of minerals is listed.
