The primary result of this field study of beach changes on the eastern 

 shore of Lake Michigan concerned the movement of the bluff or the edge of 

 the terrace marking the landward boundary of the beach. Data collected 

 every 4 weeks from August 1970 to August 1972 indicated recession or no change 

 at each of 17 profile sites on a 250-mile segment of the east coast of Lake 

 Michigan. During this period, lake levels were rising from a mean of 578.9 

 feet above mean water level (MWL) in 1970 to 579.7 feet MWL in 1972. The
