Geography

South Carolina is composed of four geographic areas, whose boundaries roughly parallel the northeast/southwest Atlantic coastline. The lowest part of the state is the Coastal Zone, which is divided into three separate areas(The Grand Strand, Santee River Delta, and the Barrier Islands), The second part going inland is the Coastal Plains, often divided into the Outer and Inner Coastal Plains, is also known as the Lowcountry. The land above the plains is known as the sandhills, which used to be South Carolina's fall line. above that is the piedmont, which contains many major cities and is hilly. The last region is the Blue ridge, which is the smallest region. It is mountainous. The Lowcountry is nearly flat and composed entirely of recent sediments such as sand, silt, and clay. Areas with better drainage make excellent farmland, though some land is swampy. The coastline contains many salt marshes and estuaries, as well as natural ports such as Georgetown and Charleston. An unusual feature of the coastal plain is a large number of Carolina bays, the origins of which are uncertain, though one prominent theory suggests that they were created by a meteor shower. The bays tend to be oval, lining up in a northwest to southeast orientation.

Just west of the coastal plain is the Sandhills region, also known as the Midlands. This region of the state is thought to contain remnants of old coastal dunes from a time when the land was sunken or the oceans were higher.

The Piedmont (Upstate) region contains the roots of an ancient, eroded mountain chain. It is generally hilly, with thin, stony clay soils, and contains few areas suitable for farming. Much of the Piedmont was once farmed, with little success. It is now reforested. At the southeastern edge of the Piedmont is the fall line, where rivers drop to the coastal plain. The fall line was an important early source of water power. Mills built to harness this resource encouraged the growth of several cities, including the capital, Columbia. The larger rivers are navigable up to the fall line, providing a trade route for mill towns.
