Orange Island
By the Early Oligocene, sea levels rose almost as much as during the late Eocene. Parts of the platform remained above water creating Orange Island, a low relief island just 150 km (93 mi) south of the Oligocene Georgia coastline and Bainbridge Subsea with a shallow channel, the Gulf Trough or Suwannee Strait, separating the two.
