If you’ve ever traveled Georgia Highway 107 between Jacksonville and Snipesville, you’ve undoubtedly noticed these large outcrops near the Coffee/Jeff Davis County line. They’re an extension of the better-known Broxton Rocks, a natural area protected by the Nature Conservancy of Georgia. The area, known as Flat Tub, is accessible as a Georgia Wildlife Management Area (WMA) and recent covenants have led to further protections of this fascinating resource.
Long thought to be Altamaha Grit, different hypotheses suggest that it could be of Altamaha Formation, but not as “gritty” as other such areas previously identified. Another thesis suggests this may be a more specific “Ocmulgee Formation”, the result of a meteorite impact which may have created the Big Bend of the Ocmulgee.
Whatever the specific geology, it’s certainly an amazing environment, almost alien in comparison to adjacent lands.
