Profile Line 13 . The till bluff at profile line 13 retreated the least of all 

 17 profile lines. The stability of the area is primarily a result of the com- 

 position of the bluff but may also be due to a coastal protuberance composed 

 of till located to the south. The major cliange between October 1973 and 

 December 1974 was a small amount of bluff recession of the bluff crest (0.3 

 meter) and a steepening of the base of the bluff. This steepening was accom- 

 panied by erosion of the beach. By May 1976, the area appeared to be seri- 

 ously eroding. There was almost no beach, and the property owner had placed 

 large concrete blocks just offshore in hopes of dissipating some of the wave 

 energy.
