Ever wondered what’s going on beneath your feet? Join California State Parks staff, where we’ll explore how the San Andreas Fault quite literally ‘rocks the bay’ at Tomales Bay State Park. Get ready to uncover Earth’s layers, crack into rock types, and explore how shifting plates and earthquakes have shaped Tomales Bay over millions of years. This program touches on geology, earth science, environmental studies, and natural history.
