Faults crossing the Reserve are most easily seen in the beach cliffs and in the Torrey Pines grade on old Route 101. The Carmel Valley Fault hits the beach about 500 yards south of Flat Rock. The Delmar Formation dips below the sand at about 100 yards south of Flat Rock but is raised up about 26 feet into view again by the fault. In thin-bedded rocks another 100 yards south, even very small faults which offset the rocks by only a few inches can be seen.
