I knew that Oakland is a compelling city when I moved here in 1989, but I had no idea how much fascinating geology there is here. Because my work on this site doesn’t earn me anything, I gratefully accept PayPal donations to support it. As I get deeper into our remarkable geology I expect to consult specialists and archives, requiring more time and local travel (which I do by bus, BART and Zipcar). I plan to field-check previous mapping and dream of adding data of my own, which would require a professional-quality field logging tool. I also have in mind the possibility of a website for the greater Bay area. I have no premiums or tchotchkes to offer, just the thanks of a guy being offered a shoestring of support for a long-term effort.

My book Deep Oakland: How Geology Shaped a City, was published in May 2023, and donations were a significant help in the funding drive I was asked to do for that project.
