This report describes, in general terms, aspects of the regional and local geology of the Coastal Engineering Research Center's Field Research Facility (FRF) in Duck, North Carolina. The FRF is located on the Outer Banks which form the seaward margin of the Atlantic Coastal Plain province in this region. The beach and dunes of the barrier island at the site of the FRF are composed of fine to very coarse sand mixed with some granule and pebble-sized material. This lithology remains essentially unchanged beneath the barrier to a depth of more than 15.2 m (50 ft) below present sea level where finer grained sediments predominate. The inner continental shelf in the area is marked by irregular bottom topography with four large shoals interrupting seaward inclination of the shelf floor. The inner shelf is mantled by fine to very coarse sand with the coarser material occurring primarily on the shoals.
