Join a volunteer Robert Irons on a 1-mile, 1-hour adventure to observe the great forces that have been manipulating Cove Beach long before humans were ever here. Uncover evidence of the hard-to-see forces that shape Año Nuevo’s beaches and cliffs and gain a perspective of California’s geological future while walking along active faults, ancient fossil beds, forgotten shorelines, and a mysterious river of sand. Suitable for all ages. Rain cancels. Event is free, parking is $10 and supports the park.
