The Friends of Sausal Creek (FOSC) invite the community to attend their environmental education presentation, "Sausal Creek Rocks!"

Oakland geology writer Andrew Alden will talk about the geology of the Sausal Creek Watershed. Geologically, Sausal Creek is a microcosm of Oakland, cutting across numerous rock types and layers. Find out how the ground we walk on every day relates to the vegetation that grows on top of it, the likelihood of landslides and earthquakes, and what mysteries lie under our feet.
