fine-grained deposits associated witti greatly sloping hills. Bedrock out- 

 crops are rare in this area. The Northern Section of the AFH Province is 

 characterized in its northern area by gently rolling terrain with occasional 

 isolated hills and in its southern area by rolling plateaus and low linear 

 mountains with broad east-trending ridges (Figure 4). The surficial geology 

 of the AFH is more complex than that in the ACP Province. The Aufeis Creek 

 study site is near a geologic contact between eolian silt deposits and 

 undifferentiated alluvial and co I I uv i a I deposits while the Kavik River and 

 Sagavan irktok River sites are flanked by remnants of moraines and associated 

 drift. The topography surrounding the Ivishak River site, near the border of 

 the ACP and AFH Provinces, is more typical of that of the White Hills Sec- 

 tion (Figure 5) while the Shaviovik River site is right at the interface of 

 the two provinces. The area to the south and west of the Shaviovik River 

 site is flat while that to the north and east is predominated by mildly 

 sloping hi I Is up to 360 m.
