Detailed topographic form of the inner shelf off Panama City, Florida, a region of clastic deposition (depths given in feet). A smooth-sloping gradient extends to a depth of 40 feet; pre- sumably this is a near-shore marme profile of equilibrium. But greater depths are marked by a rough relict topography. A submerged forest is located at the point marked X having a radiocarbon date indicating an age in excess of 40,000 (after Dietz, 196

However, sub-bottom acoustic profiling (Moore. I960) has demonstrated many wave-cut terraces partly hidden beneath a thin veneer of late Holo- cene sediments. These terraces are separated from BAY SILT^ PEAT . 1\ - V ^^^^77777777777/ BEACH RIOGES ICMENIERS) ^-^ytv* \ ^^^ PLEISTOCENE ^'^'^'^^^^^^^^^ ^^^77777) MOOERN ACTIVE PARALIC WEOOE '/77; W777/W77?77/M CONTINENTAL TERRACE -V ^^^^^^^ CONTINENTAL BLOCK.
