Thousand Islands (Cocoa Beach) deposit include the existence of a layer of plain sand (often containing terrestrial vegetation debris) sandwiched between sediments containing numerous small bivalve mollusc shells that are indicative of deposition in a normal lagoon environment.

The relatively low topography and rising water
