Andrew Alden, author of Deep Oakland

I'm a longime writer intensely focused on geology. I like to turn Oaklanders on to the secret beauties of our landscape in talks and walks. Since the 2023 publication of Deep Oakland: How Geology Shaped a City, I've been expanding my repertoire of walks. Some are simple, some are strenuous, all are interesting.
