Summary:
Barrier sand deposits exposed near Smith Gut and at the Pine Cliff Recreation area in the Neuse River valley, Pamlico Co., NC, are here named the Arapahoe Sand Member of the Flanner Beach Formation, following the informal usage of Mixon and Pilkey (1976). The Member consists of cross-stratified, fine to coarse sand, sandy mud, and pebbly sand with clay laminations and cylindrical burrows. Gradationally overlies the Smith Gut Member of the Flanner Beach; intertongues to the west with the Beard Creek Member of the Flanner Beach and is truncated to the east by the Suffolk (Grantsboro) Scarp. Thickness is up to 7.5 m. Age is middle Pleistocene.
