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.
1
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.
2
Seismic action pushed this sedimentary rock above sea level.
3
Waves carved away at the shoreline, eventually they cut the slice of rock layers you see here today.
