Deep is the Coastal Plain

The shoreline reflects the regression that resulted from the last significant glacial advance of the modern ice age. Throughout the Cenozoic era, the Coastal Plain extended 400 kilometers (250 miles) into the Gulf of Mexico, with sediment deposits 15,000 to 18,000 meters (50,000 to 60,000 feet) thick.

A coastal plain is a flat, low-lying piece of land next to the ocean.
