Figure 3-8. Depth difference comparison displaying the sediment deposits formed during 

 the 1991-92 disposal season. Gray shading represents sediment placed prior to 

 mid-December 1991. Yellow shading represents sediment deposited from mid- 

 December to mid-January 1992. It is likely that many of the smaller areas of 

 apparent accumulation surrounding the central deposit are the result of survey 

 artifacts and are considered artificial.
