9 May 1976 - View 

 from edge of road- 

 way toward profile 

 line (see diagram 

 on facing page). 

 Profile line runs 

 next to the first 

 tree from the left. 

 Note narrow beach 

 and shoreline off- 

 set. 



23 April 1974 - Relatively wide 

 beach with extensive band of 

 heavy mineral sand. 



Profile Line 8 . As mentioned in the text, profile line 8 proved to be one of 

 the more interesting lines. Recession of the steep sand bluff had occurred 

 more or less sporadically during the first 3.5 years of surveying. Then in 

 1974 the beach and bluff eroded significantly. The bluff retreated 10 meters 

 as the active erosion moved upward 4 meters. The dramatic increase in erosion 

 caught the surveyors by surprise and the bench mark was lost in April 1974. 

 The close proximity of the profile line to the reveted roadway may help to 

 explain this severe erosion, which has continued. In May 1976, the bench mark 

 was found lying on the bluff face. This is an indication that an additional 2 

 to 3 meters of bluff had eroded in the 1.5 years after December 1974.
