A wide beach was present at the start of the surveys, but beach erosion 

 occurred during August 1970. An alternation of monthly accretion and 

 erosion preceded ice formation. After ice breakup, the beach appeared the 

 same as it had during initiation of the study. There was minor erosion in 

 June and essentially no change throughout the remainder of the first year. 



Although the beach remained the same through the summer, significant 

 beach erosion occurred about 500 feet to the north such that the profile 

 line crossed a marked beach protuberance. No significant change occurred 

 through the fall, but there was apparent accretion during December, fol- 

 lowed by minor bluff erosion before ice formation. Minor accretion fol- 

 lowed ice breakup but erosion prevailed throughout the rest of the year, 

 resulting in almost no beach. 



After modest accretion in August 1972 there was slight erosion. Much 

 bluff recession occurred in late fall. Accretion followed ice breakup in 

 the spring and there was erosion again in June 1973. 



1. Profile Site 12 . This profile is located near a marked change in 

 coastal geology. There are high bluffs of glacial drift to the south and 

 large, stabilized dunes to the north. A rather broad terrace was present 

 at initiation of the study. Like site 11, this site is highly developed 

 with residences. 



A wide, well-developed beach was present during the first survey. 

 Swash marks indicated that the entire beach was covered before the 

 September 1970 survey, but erosion was slight. There was significant beach 

 and terrace erosion in late fall. Modest accretion occurred in March 1971, 

 but erosion prevailed in April. 



There was little change during the fall of 1971 except for minor ero- 

 sion in September. Much beach and terrace erosion took place before ice 

 formation, and substantial accretion occurred after the spring ice break- 

 up. This led to a wide beach through the summer. 



The fall of the third year was one of continued erosion. Spring of 

 1973 was a period of net erosion, although there was beach accretion just 

 after shore- ice breakup. 



m. Profile Site 13 . High clay-till bluffs dominate the coast for 

 several miles in either direction. The active beach abuts against the 

 bluff with no sand terrace. This is the only profile line which is near 

 a small natural barrier to sediment transport, a coastal protuberance 

 composed of Pleistocene till a few hundred yards to the south. This 

 location has been monitored since June 1968 as part of another study 

 (Davis, 1972) . 



A wide beach present at the beginning of the study remained stable 

 until September 1970 when continued fall beach erosion began. Much accre- 

 tion followed and then substantial beach erosion.
