Uniformitarians propose that the last major sea-level rise began with the close of the Wisconsin Ice Age 14,000 to 18,000 years ago. Approximately three to five thousand years ago sea level stabilized to its near-present-day level. According to uniformitarian archaeological estimates paleo-Indian cultures have existed in Florida for 10,000 years. Many paleo-Indian sites have been identified across the state with some found underwater, both on and offshore. Large offshore submerged sand dune fields are believed to have become drowned with the last rise in sea level. Many of these same subaqueous sand dune fields contain in situ tree stumps within the swales, reflecting once living maritime forests. These former forests existed on the continental shelf at various sea-level lowstands during the Pleistocene. We propose that the now submerged paleo-Indian sites, sand dune fields, and paleo-forests reflect former subaerial environments that were rapidly drowned with the last sea-level rise approximately three to six thousand years ago (associated with the close of the Young-Earth Flood Model–Ice Age Timeframe).
