was infrequently flooded by tides and supratidal vegetation had been able to 

 expand onto the salt marsh. In 1978 Spartina patens occupied only a narrow 

 band 50 meters wide at the back of the barrier; Spavtina alt ermi flora was not 

 present at belt C (Fig. 113). The Ammophila bveviligulata duties were 9.5 

 meters high and 110 meters broad. The center 100 meters of the belt was 

 occupied by a well-developed dune-heath community dominated by Hudsonia 

 tomentosa, Cladonia spp., and declining and dying Ammophila bveviligulata. 



Belt E is located at a wide section of Old North Beach in the approximate 

 location of the 1626 inlet (Fig. 90). In 1868 a washover was evident, backed 

 by a continuous dune line and a broad creek with salt marsh to the west (Fig. 

 114). Between 1868 and 1886 the area was overwashed, filling the creek and 

 extending the subaerial barrier about 335 meters landward. Dune and salt- 

 marsh vegetation covered this washover by 1886. 



Although the dune line at belt E has not been disturbed by overwash since 

 1886, the salt marsh has been affected by overwash several times. In 1938 

 belt E consisted of a continuous dune line backed by a washover deposit on 

 part of the marsh. This washover, which crossed the dune line north of belt 

 E, must have occurred first prior to 1938, since dunes were already evident 

 at its outer margin, and scattered dune remnants probably would not have 

 rema ined.
