[1] The Rocks, as it is referred to locally, consists of a series of cracks, pools, damp cliff walls, a 10-foot (3.0-meter) waterfall, and rugged outcrops up to 20 feet (6.1 meters) high, all carved into a shallow gorge over many centuries by Rocky Creek.

Part of the Atlantic coastal plain, Broxton Rocks' sandstone layers were created by the slow erosion of the Altamaha Formation, dating from the Middle Miocene era.

The preserve lies in an area of longleaf pine ecosystem which once stretched from the Atlantic Ocean to the eastern reaches of Texas.

Other animals include the armadillo, the woodrat, the flying squirrel, the vulnerable* gopher tortoise, and the threatened* indigo snake.
