Below are a few candid photos taken during this educational outing.  These rocks formed in a deep ocean trench between 170 and 30 million years ago. Their diversity is astonishing. Meet north of Cayucos at the parking area on the west side of Hwy 1, 1.7 mi. north of the Hwy 1/Cayucos Drive interchange. (Active) 4mi., 3 hrs.
