was removed. Sites such as Aufeis Creek on the North Slope and Penny River 

 on the Seward Peninsula each included 8 of the 12 specific site locations 

 that were possible (Table I). This complexity made it difficult to identify 

 any specific floodplain changes with specific gravel removal locations. For 

 these sites, the overall effect on the floodplain resulted from the total 

 gravel removal operation and specific effects were masked. The problem of 

 sites with multiple Gravel Removal Area Characteristics was unavoidable 

 because almost all of the over 500 sites originally considered reflected the 

 same situation. The major result is that, in some cases, generalities are 

 discussed with little or no reference to specific material sites. If none of 

 the sites clearly exhibited the relationship being discussed, none were 

 cited as examples. However, the generalities discussed are considered ac- 

 curate because of the analyses and conclusions reached in the preceding 

 disciplinary chapters.
