A literature review as well as a consultation with a geomorphologist, Dr. Christopher P. Williams, at the Florida Geological Survey (FGS) were both performed in order to understand the state of knowledge on relict shorelines in peninsular Florida. This knowledge was compiled into a map, Figure 1, that shows the locations and relative ages of geologically confirmed relict shorelines in the Florida peninsula. A number of additional required areas of research in order to “complete” the map are then discussed. The project highlights both the rapidity of Florida’s Pliocene-Pleistocene coastal evolution and the relatively high amount of incompleteness still present in the current state of knowledge on Florida relict shorelines.
