9 May 1976 - View to 

 north showing wide 

 sand beach. Note 

 offset between beach 

 and seawall (to left 

 of white tower). 



12 August 1974 - Narrower beach than 

 shown in photo above; well-vegetated 

 dune crest. 



Profile Line 4. Davis (1976) speculated that this sand dune profile line may 

 be affected by a seawall located about 100 meters to the north. This is not 

 unlikely as the dune at this profile line retreated more than any of the other 

 profile lines during the study. Only 0.6 of the total 19.5 meters of reces- 

 sion occurred between October 1973 and December 1974. The beach was very 

 active with evidence of both overall beach accretion and erosional scarps 

 appearing in the 4-week interval between surveys. There was a net increase 

 in beach volume between October 1973 and December 1974.
