This limestone bedrock is Pleistocene in age and highly vegetated. The outcrop was heavily influenced by iron staining. This accumulation represents young sediments deposited at the shoreline. These ridges are thought to represent paleo-shorelines and to be possible sites of future barier reefs during future sea level transgressions. These ridges parallel the present-day barrier reef.
