The Okefenokee Swamp is the most extensive of Georgia's natural wonders in terms of area. This wildlife refuge in southeastern Georgia covers about 700 square miles and makes up part of four counties. The Okefenokee (from the Seminole, meaning "land of trembling earth") includes a wide variety of ecological features, ranging from sandy ridges to wet, grassy savannahs and marshes to narrow water channels and small islands, all of which support a vast range of flora and fauna.
The Tallulah Gorge in northeast Georgia is a canyon formation 3 miles long and 1,200 feet deep. It was created by a series of waterfalls that were dammed by the Georgia Power Company in 1912. Named after a Native American word for "terrible," Tallulah Gorge was traditionally feared as a home for evil spirits. It was among the most visited tourist destinations in the state in the late nineteenth and early twentieth centuries.
