Abstract

New evidence invalidates the former concept that Pleistocene shorelines are "terrace" cut and fill structures. Comparison of Pleistocene and Holocene sediments with morpholo gy of the shoreline indicates that Pleisto cene deposits accumulated in barrier island environments and that the "ter races" are former lagoon-salt marshes. Stratigraphic evidence supports six ma jor Pleistocene shorelines below an elevation of 100 feet (30 meters).
