 The cemetery is located in the center of Sapelo Island, towards the south end, 1‑1/4 miles west of Hog Hammock.
 It was originally associated with a former community named "Behavior" and slaves of the Thomas Spalding Plantation.
 An example of African-American burial grounds, the cemetery's grave markers include short posts at either end of the graves with epitaphs on wooden boards nailed to the surrounding trees and personal items included with the deceased.
 More recent tombstones are cement, granite or metal.
