Mines of the American West - Alameda County, California Ivan Herring

This is the Second Edition of Alameda County, which was the seventieth book in a series of books on Mines of the American West and the fiftieth on counties in California. This book contains over 230 entries covering mines, historic mining companies and mining districts in Alameda County. (That's about 5% more mine entries and 25% more data than was contained in the First edition.) The books are intended for the use of small miners, "rockhounds", metal-detector enthusiasts, hikers, campers, off-roaders and others. Modern GPS coordinates, most of which are from USGS records, have been associated with the majority of the records to allow the reader to do a little "prospecting from their computer", using available on-line tools. In this book many of the locations have been reviewed using on-line tools, especially when attempting to locate the mine through the use of the coordinates. This allows the locations of the coordinate points to be visibly identified; and, in many cases the best ways to access them. Where I have been able to find a reference as to the "location accuracy" of the coordinates, I have included it. On-line mapping tools allow the reader to pursue their interests and review locations when the weather is bad or they only have limited blocks of time. It also will allow the reader to maximize their use of time when they can physically visit the areas, after getting permission of the Owners, when necessary. Also, as a benefit to physical site visitors, some of the mines have been grouped by Mining District, where such existed. Some of the entries for these Counties have been developed while I was working on other projects ranging from developing data for other book series to various consulting assignments.
