coastal plain

Coastal plain is used especially in the Carolinas and eastern United States to refer to the land between the Piedmont and the ocean, from New Jersey all the way around to Texas’s Balcones Escarpment. The term is understood to mean the belt of flat or almost flat land made of sand- and sea-deposited minerals reaching from the shore to the fall line. The coastal plain is characterized by pine forests, shallow lakes, white sandy soil. Cities such as Richmond, Virginia; Fayetteville, North Carolina; and Columbia, South Carolina, are set at the edge of the coastal plain where navigation was halted by rapids on the rivers and where the hill country begins. “At intervals, the Atlantic has advanced and retreated across the Coastal Plain,” writes Michael A. Godfrey in Field Guide to the Piedmont.
