About this map

The Okefenokee National Wildlife Refuge dominates this section of Charlton County, revealing the intricate water and land patterns of the Okefenokee Wilderness. This environment is defined by an expansive mosaic of open water and aquatic prairies, including Carters Prairie, Redbird Prairie, and Durdin Prairie, which are interspersed with isolated landforms known locally as hammocks and islands. Notable elevations like Floyds Island and Grassy Island rise above the surrounding Okefenokee Swamp, providing critical dry ground within the wetland complex.

Along the eastern margin, the Trail Ridge forms a distinct geological boundary, where human infrastructure begins to meet the wilderness. This transition is marked by a network of local connectors such as Swamp Perimeter Rd and Mizell Rd. The map illustrates the preservation of this unique ecosystem, highlighting the scale of inland water bodies like Sand Lake and the various prairies that fluctuate with the seasonal water levels of the Georgia wetlands.
