Coastal Plain Georgia

Cobb County, GA is the perfect location for Southern charm. However, many newcomers to Georgia find that it isn’t quite clear how to step into the culture. A visit to landmarks like The Carter Center may provide a sense of history, but it doesn’t tell you much about the southern lifestyle. It’s time to hit the books (and the streets) to really understand the city.



Georgia is, there's no denying it, a beautiful state. From the pines to the coasts, it's well worth taking the time to explore. It's also got great barbecue, but that's a different matter. In terms of its geography, Georgia can be divided into five major regions. The largest of these is the Coastal Plain, a relatively flat zone along the Atlantic coast. The Coastal Plain makes up about 60% of Georgia's landmass, making it the largest region in the state. To many people, to miss the Coastal Plain is to miss Georgia, and that's something you certainly wouldn't want.

The Coastal Plain region makes up roughly the southeastern half of the state, and thanks to its history, has some pretty clear borders. The Coastal Plain is the part of Georgia that was once under water and part of the Atlantic Ocean. That's what made it so flat. So, the northern inland borders of the Coastal Plain represent the ancient shoreline, where the land was no longer under water. The result is a sharp increase in elevation at this point, where the land become less smooth and uniform. We call this point the fall line. The elevation change means that rivers flowing across this point don't gradually decline; they suddenly fall. In fact, the numerous waterfalls along this border is why we call it the fall line.

Just off of the eastern shore are a series of islands that make up the furthest eastern parts of the Coastal Plain. Running parallel to the shore, they form a break between the major ocean currents and the shoreline itself, which is why we call these barrier islands. Thanks to these barrier islands, collectively called the Sea Islands in Georgia, the continental shoreline itself does not get massive waves. Georgia's 14 Sea Islands are basically massive sand dunes, larger than the ocean is deep at those spots, and are covered in dune grasses. Some are wildlife preserves as well, where sea turtles arrive annually to lay their eggs.

Sand dunes are a prominent feature on Cumberland Island, one of the barrier islands lining the coast of Georgia. Facing the ocean on the eastern side of the islands, the sand dunes are formed by wind and waves and stabilized by such plants as sea oats and morning glories. (Source: www.georgiaencyclopedia.org)
