Great sourcebook to read when traveling; what's the land here, and here, and how did it get this way? What are we seeing? How cool is it that Twin Peaks in SF are made up of very different things, bonking into one another? Great car reading. ( )

I'd love to say that I have the fortitude to just sit down and read through this book. It is knowledge that I would love to have... but have a hard time getting. It is arranged as a serious of surveys along various highways in Northern California. One problem is that "Northern" California always tends to start right in my town as far as books are concerned. So many of the areas I would be interested in get split into another volume. But to the best of my knowledge, "Roadside Geology" doesn't exist for Southern California. I read through the introduction and a couple of the areas that I am very familiar with, but I leave to rest as reference sections for road trips that I'll take some day.
