The Okefenokee Swamp is a shallow, 438,000 acre (1,770 km²), peat-filled
wetland straddling the Georgia–Florida border in the United States. A majority
of the swamp is protected by the Okefenokee National Wildlife Refuge and the Okefenokee
Wilderness. The Okefenokee Swamp is considered to be one of the Seven Natural
Wonders of Georgia. The Okefenokee is the largest "blackwater" swamp
in North America. The term Okefenokee in Native American is "land of
trembling earth". The swamp was designated a National Natural Landmark in
1974
