Figure A-4. The top photo shows a 65-meter-high bluff (behind profile 

 station 25) which is composed primarily of sand, but was 

 protected from wave attack during the study period by a 

 narrow beach and foredune that survived this period of 

 erosion. The lower photo shows the highest dune under- 

 mined by wave erosion. By 1976, the unstable slip face 

 extended almost to the top of this 37-meter -high dune at 

 profile station 19.
