The plaque says, "You'll count more than seven layers in the rock cliffs
around this cove. Yet, the cliffs are indeed a slice through
a sediment story that's 75 million years old. The layers
formed when this spot was 3,500 feet under the sea.


Mud and sand eroded from the shore. They flowed into the ocean, cutting a channel into the sea floor. These sediments spread out in layer after later. Over millions of years, the weight of all these laters compressed the sediment into rock.


Seismic action pushed this sedimentary rock above sea level.


Waves carved away at the shoreline, eventually they cut the slice of rock layers you see here today.
