A modest beach was present at the beginning of the study. After an 

 initial period of beach erosion, some accretion occurred in October 1970, 

 followed by more erosion up until shore-ice formation. After the shore- 

 ice breakup, the beach was similar to that at the start of the study, and 

 a swash bar was present. Growth of the beach continued although there was 

 some erosion in May and July of the first year. 



Late summer of 1971 was characterized by modest erosion followed by 

 accretion. Erosion was dominant during the late fall high-energy period, 

 and minor beach erosion and bluff recession followed the melting of shore 

 ice. This continued through the remainder of the second year. 



Early fall was a period of much beach erosion although there was accre- 

 tion in the usually high-energy month of November 1972. The spring of 

 1973 was marked by erosion to the extent that by June there was no beach 

 and about 1 foot of water at the base of the bluff. Slumping and some 

 recession of the bluff also occurred in this period. 



p. Profile Site 16 . Although small vegetated dunes occupy the coast 

 adjacent to the profile at this site, there are extensive bluffs of gla- 

 cial drift which begin less than 1 mile north of the profile site. A 

 narrow and somewhat discontinuous foredune terrace was present in this 

 area until the summer of 1969. This location was also the site of a time- 

 series study (Fox and Davis, 1970a). During that study an extremely sev- 

 ere summer storm ,was monitored (Fox and Davis , 1970b) which provided some 

 insight to beach and coastal erosion. 



A fairly well developed beach with heavy minerals in the backshore 

 area was present at the beginning of the study. After initial beach eros- 

 ion there was much accretion in October 1970. Severe storms in November 

 1970 drastically reduced the beach, but by the next month it was back to 

 its original condition although the dune had eroded 4 feet. After ice 

 melting there was accretion, followed by minor terrace erosion in May and 

 July 1971. 



Late summer and fall of 1971 were periods of modest erosion. Accretion 

 followed the breakup of shore ice. The summer of 1972 was characterized 

 by stability. 



September 1972 was a period of much beach erosion, followed by slight 

 accretion. The beach remained rather narrow immediately after ice breakup, 

 followed by much accretion during the next few months. The beach was much 

 wider at the end of the study than at its initiation. 



q- Profile Site 17 . The coastal area at this site is comprised of 

 high bluffs of glacial till with sand terraces between the bluffs and the 

 active beach. About 1 mile to the north, dunes dominate the coast, con- 

 tinuing for several miles. Nearshore profiles were surveyed at this site 

 the summer of 1963, a time of extremely low lake level (Davis and McGeary, 

 1965) .
