The bluff is a wave cut terrace from the Pleistocene and contains lots of shells, most of species still which are alive. A ladder is useful. Capitola, near Santa Cruz, on the beach. Clams, snails and sand dollars. Fossils can be found sandstone sea cliffs and in the talus rubble that falls on to the beach.
Low tide is the best tune to go.
Go a few hundred yards south of the Esplanade at Capitola past the sewage outfall. Valmar becomes Old Topanga Canyon Road. Turn left and proceed up Old Topanga almost a mile, past the point where the road switches back upon itself. From this point until the top of the hill, you will encounter fossiliferous road cuts on your right. The first embankment contains a massive oyster reef.
