Shell Bluff, Burke County, Georgia
is an extremely scenic and noteworthy bluff overlooking the Savannah River.
It is located in the inner coastal plain just south of the Fall Line in
Burke County, Georgia, and has a nearly vertical face that rises over 100
feet directly above the river. This cliff-like face is chalky white (due
to material weathered from limestone) and has an eastern to northeastern

The combination of the northern and northeastern exposures of the bluff, the steep topography, the limestone-derived soils, the absence of frequent fires, and the temperature buffer and humid conditions due to the Savannah River below, have led to the development of Southern mixed hardwood forest supporting a number of species characteristic of more northern lines of latitude. Species present such as green violet (Hybanthus concolor), wild ginger (Asarum canadense), sweet cicely (Osmorhiza longistylis), black cohosh (Cimicifuga racemosa), ravine grass (Brachyelytrum erectum), starry campion (Silene stellata), tall bellflower (Campanulastrum americanum), and black walnut (Juglans nigra) are found primarily in the Ridge & Valley, Blue Ridge, and upper piedmont of Georgia. At and near the crest of the bluff, an altered longleaf pine-turkey sandhill community is present and supports a very different, fire-adapted flora when properly managed.
