placement in 1970 of an additional 635,000 cubic meters of beach material 

 between Oriental and Illinois Avenues (see Figs. 31 and 32). The fill mate- 

 rial in each case was similar to the natural beach material, with a mean grain 

 size of 0.3 millimeter. Again in 1970, profile line 3 indicated a trend to 

 maintain much of the fill for an extended time period (Fig. 33). Although 

 surveys were not conducted after 1973, it can be assumed that some of the fill 

 migrated down the beach to the other profile lines as did some of the 1963 

 fill. Some information supporting this assumption is shown by comparing the 

 photos in Figures 34 and 35 (taken in November 1970) with the photos in 

 Figures 36, 37, and 38 (taken in March 1979 at profile line 2). Note the 

 considerable amount of beach after the beach fill in 1970, compared to the 

 practically nonexistent beach in 1979. Also, note the wide beach in Figure 39 

 (taken at profile line 6 in March 1979) compared to the lack of beach in Fig- 

 ures 36 and 37 .
