Cumberland Island Feature
During the last Ice Age (10,000 years ago) this area was part of the ocean floor. As the ocean receded, a dune line formed, which acted as a dam, forming today's refuge. The Seminole Indians named the area Land of the Quivering Earth. And if you have the good fortune to walk one of the many bogs, you can find the earth does indeed quiver like Jell-O in a bowl.
