8 May 1973 - Major 

 feature is width of 

 beach. 



8 May 1976 - Similar view 

 as above but 3 years later. 

 Beach is narrow or non- 

 axistent; bluff is steep 

 and recently eroded. 



Profile Line lb . As mentioned In the text, line 16 Is probably the most Interesting profile line In 

 terms of changes between October 1973 and 1974. During this time period, the entire profile (both 

 beach and bluff) eroded, losing more than 85 cubic meters per meter of sand. The sequence of events 

 was for severe beach erosion In November and December 1973 followed by recession of the bluff begin- 

 ning in January 1974. Except for a period of bluff stabilization and beach building In May 1974, the 

 erosion continued through all of 1974. Field trips in May and October 1976 found narrow beaches and 

 an assortment of concrete and sandbag shore protection devices along the shore southward from profile 

 line 16. The cause of this erosion is discussed In Section V, 4 and in Birkemeier (1980).
