The California Geological Survey, previously known as the California Division of Mines and Geology, is the California state geologic agency. Although it was not until 1880 that the California State Mining Bureau, predecessor to the California Geological Survey, was established, the "roots" of California's state geological survey date to an earlier time.

Only recently has the astonishing modern theory of moving crustal plates enabled us to understand fully how the picturesque landscape of the San Francisco Bay Region and its surrounding areas has come into existence. In this book Howard tells the dramatic story, illustrated by clear, graphic sequential drawings: the continual remaking of the earth’s surface on a time scale so immense human minds can scarcely grasp it.

The maps are fantastic, and really give you a good idea of how this part of California came together. We learned that Santa Cruz's Ben Lomond Mountain, plus the Gabilan range plus the Big Sur/Santa Lucia range were at one time part of the channel island chain. They were part of the Pacific Plate that crashed into the North American Plate. At first the Pacific Plate was slipping under the NA plate, creating a chain of volcanoes in the Sierra Nevada mountains. Then the Pacific Plate started moving to the Northeast, at which point subduction slowed and uplift began. It was during this uplift period that the three islands crashed into North America and formed the Central Valley, Salinas Valley, Monterey Bay, and the San Francisco Bay.

I also discovered that the Sand Hills of the Santa Cruz mountains were once the river bed of an ancient outlet for the Central Valley, probably exiting through the Pajaro Valley, before uplift closed off that part of the coastline.

The maps are extremely well drawn and the only drawback is that the book is so small, you need a magnifying glass to really appreciate the author's artwork.

I find the entire study very comforting for the future, because it gives you an idea of how our present geography is just a brief snapshot of a vast process by which the state of California is gradually being carried away by the Pacific Plate, and will one day form an Island or Isthmus-- breaking away from the continent at the Eastern Sierra, from the Gulf of California at least up to Lake Tahoe. One day, Lake Tahoe will be the northernmost bay of an inland sea reaching up from Baja California, and Reno will be beachfront property! Best of all, there is NOTHING we humans can do to either stop the process or even slow it down.

If you live in any part of Central California, this book is essential to understanding our geography.

This book is easy to understand. The illustrations make it easier to understand the changes that have happened in middle California for the past 200 million years.

This brief introduction to the geologic history of the Bay Area and beyond is impressive. The
author is a distinguished geologist and geomorphologist, retired from Stanford. He writes in a clear, direct style, avoids professional jargon, and clearly knows the area in detail. One of the best features is a series of hand-drawn block diagrams illustrating the landscape of the study area as it changes over time. These are marvelously-detailed, old-fashioned maps, and their only flaw is being presented in a reduced format that's hard for these old eyes to read.

The guide, published in 1979, is out of print, but readily and inexpensively available. Fits comfortably in a jacket pocket or car door. My expertise in California geology is limited, but I don't think anything here will seriously mislead you, even 30+ years on. And there's nothing else available that covers this whole region: Geology of the San Francisco Bay Region (California Natural History Guides) covers just the immediate Bay Area. Recommended.

Google Books has an extended preview; link in first comment.

Happy reading--
