In 1978 the dune line at belt F was 140 meters wide and 5 meters high 

 (Fig. 117) o Small areas of senescent Ammophila breviligulata with Chrysopsis 

 falcata (sickle-leaved aster) and Artemisia caudata were located behind the 

 foredunes. The salt marsh was broad and clearly divided into high and low 

 marsh.

In 1978 a narrow but high (5 meters) dune line separated the pond from the 

 ocean (Fig. 119). Small stands of Spartina patens, remnants of the earlier 

 salt marsh, lined the eastern pond margin except where shrubs were present. 

 TypTia latifolia (cattail) had filled much of the pond. Below Nauset Heights 

 the dune community was sparsely vegetated and dominated by Artemisia caudata 

 and Ammophila breviligulata.
