pip. No^' 2lY' CORALVILLE RESERVOIR — CALDWELL 141 



Apparent spatial relationships lie with cultural manifestations to 

 the east and northeast. The major apparent emphasis lies with the 

 Effigy Mound Culture of northwestern Illinois and southern Wis- 

 consin, although closer ties with as yet undefined foci in Iowa are 

 suggested. 



In total, the aboriginal occupation of the Coralville Reservoir was 

 not intensive. An extended temporal range is indicated, but at no 

 time was population numerous. There is no reason to consider the 

 area more than peripheral to adjacent developments. Beaubien 

 (1953 a, p. 56) has noted that northeastern Iowa is "clearly marginal 

 to the primary growth of both cultures [Hopewell, and Effigy Mound 

 Aspect], and it is not evident that a 'pure' complex of either has 

 been strongly developed in the area." 



The Coralville data strongly reinforce this presumption. It is 

 evident that a generic tie to Effigy Mound and Hopewell exists, but 

 a detailed statement of areal-temporal relationship on a focus or 

 aspect level must await future excavation and mature synthesis.
