Analysis of 58 closely-spaced bathymetric and seismic profiles of the Carolina continental slope from the northern Blake Plateau to the vicinity of the North Carolina-Virginia state line (latitude 32• 30 'N to 36• 30 'N) indicates sharp contrasts in quantity of slumping and outcrop ledge continuity.

Terrestrial progradation and a relatively gentle slope characterize the area south of Cape Lookout, especially between Cape Romain and Cape Fear where sediment mantling is the greatest. Submarine canyons, slumps, and a steep slope are characteristic Between Cape Lookout and Cape Hatteras. North of Cape Hatteras, canyons and slumps are also common, though sediment mantling lowers the slope declivity.

Upper Cretaceous through Quaternary rock samples have been dredged from the area. However, only one laterally consistent outcrop ledge, an Eocene limestone unit, is evident in the area. This ledge extends from 1500 m depth off Cape Lookout to 2000 m depth off Cape Fear.
