Today we have Andrew Alden on the show. Alden is a geologist and geoscience writer who has worked for the US Geological Survey and reported for KQED and Bay Nature. Long fascinated with rocks and landscapes, Alden found inspiration for his debut book, Deep Oakland, in the 1989 Loma Prieta earthquake, which, as he writes, “ripped the city open and revealed to us its heart and character.” Through his writing Alden raises awareness for what he calls the deep present: the appreciation of the ancient underpinnings that shape the modern-day surroundings of daily life.
