History and Geography

Sea Island was developed in the 1920s by the Rockefeller family, while Auburn University was chartered in 1856. The route crosses the Altamaha River, one of the largest undammed rivers in the East, and passes through the historic city of Macon, founded in 1823 on the Ocmulgee River.

Natural Landscapes

The route crosses four distinct landscapes: salt marsh and barrier islands near Sea Island, the flat pine barrens of the Coastal Plain, the Altamaha River floodplain, and finally the red clay hills of the Piedmont. The transition is gradual, with the most dramatic change near Macon where the fall line creates rapids on the Ocmulgee River.
