The roughly 348 Nautical Mile, NM² of this hardbottom region lies south of the Salient (geography), panhandle coast and northwest of Tampa Bay between 28° 10' and 28° 45' N and 084°00' and 084°25' W Geology The ridges consist of unconsolidated marine calcareous muddy sand, about 12 meters (40 feet) thick, overlying a weathered, fossiliferous limestone of Miocene age (between 5 and 22 million years old) and capped by a carbonate rock composed primarily of the sessile vermetid gastropod Petaloconchus sp.
