Join docent Larry Modell, a long-time advocate for public open space, and and our co-sponsored/co-hosts Sonoma Mountain Preservation, to explore Lafferty Ranch Open Space on upper Sonoma Mountain and get a view from the perspective of deep time and the flow of water. Learn how the San Andreas Fault is connected to the formation and shape of Sonoma Mountain, from which water flows to San Pablo Bay and the Pacific Ocean.
