alongshore erosion with seaward advance occurred between 1856/57 and 1875. 

 However, net change between 1856/57 and 1983 has been alongshore (550 m) and 

 landward erosion. A prominent spit extended southwestward in the late 1800 's 

 forcing Capers Inlet southwest. However, over 700 m (12 m/year) of alongshore 

 erosion removed the spit by the 1921 survey. Between 1934 and 1983, the pat- 

 terns reversed, and accretion occurred (240 m) to the southwest again, 

 although landward of its former position. This coincided with accretion on 

 Dewees Island resulting in a switch from a updrift offset inlet to a downdrift 

 offset inlet. The inlet throat, approximately 600 m wide in 1856/57, 

 increased to approximately 670 m in 1875 and then decreased steadily to 

 approximately 300 m wide by 1983. 

 Price Inlet (Maps 14 and 15) 



137. The 1856/57 survey for the southwest side of Price Inlet is incom- 

 plete, but it suggests approximately 1,400 m of northwestward spit accretion 

 by 1875. The 1875 survey shows a well-formed spit with a small bay behind. 

 Between 1875 and 1983, spit length remained constant, as did position of the 

 inlet. Inlet width decreased from 1875 (300 m) to 1934 (240 m) , but remained 

 constant between 1934 and 1983. However, despite alongshore consistency, the 

 seaward shoreline of Capers Island advanced and retreated considerably in the 

 inlet vicinity. The southwest shoreline eroded from 1875 to 1921, accreted 

 from 1921 to 1934, eroded from 1934 to 1962/63, and finally, accreted between 

 1962/63 and 1983. Northeast of the inlet, fairly stable alongshore shorelines 

 had a similar, although inverted, history of cross-shore shoreline change. 

 The shoreline accreted from 1875 to 1921, eroded from 1921 to 1934, accreted 

 to its maximum seaward position by 1962/63, and eroded slightly between 

 1962/63 and 1983. Observed 180-deg out-of -phase relationship of onshore/ 

 offshore erosion/accretion has been discussed by FitzGerald (1984) , who 

 attributes it to e~bb channel migration and associated welding of ebb delta 

 features onto adjacent shorelines. 



Bull Bay (Maps 15. 16 and 17) 



138. Northeast Point forms the southwestern boundary of Bull Bay. Bull 

 Island has been undergoing rapid erosion on its eastern end, driving it in a 

 landward direction since 1875. Losses resulting from erosion have ranged from 

 20,000 to 35,000 m 2 /year over the interval of data. Despite overall losses by 

 erosion, Northeast Point accreted alongshore approximately 790 m between 1875
