Pap.No!"2lT' CORALVILLE RESERVOIR — CALDWELL 129 



in southeastern Minnesota. A similar situation is noted for the Mille 

 Lacs Aspect, Kathio Focus (Wilford, 1955, p. 135). 



Lithic and Other Materials 



Plotted distributions within the site are based upon a small sample : 

 typological groupings are small, and obviously are not a suitable basis 

 for a detailed comparative attack. 



Projectile points. — The relationship or association of specific point 

 types with temporal and regional pottery assemblages in Iowa is cur- 

 rently unknown. Further, the situation is by no means entirely 

 clear throughout the upper Mississippi Valley. Only local associa- 

 tions are known in some detail. Despite the obvious inadequacies in 

 the current sample and in the comparative data, the following gen- 

 eralizations are offered (figs. 20, 22). 



Projectile points or pointlike knives occur only in the upper por- 

 tions of the deposit. The vertical distribution is entirely above the 

 2.5-foot level. Within this stratigraphic range, stemless projectile 

 points with regular or notched margins are slightly more frequent 

 than stemmed forms. Further, the stemless forms exhibit a discon- 

 tinuous but considerably longer continuity than do the stemmed 

 examples. With three exceptions, the point inventory can be related 

 to a generalized middle to late Woodland category. Specific an- 

 alogues are frequent in Illinois, southwestern Wisconsin, southeastern 

 Minnesota, and in northeastern Iowa (see Rowe, 1956, figs. 23, 25). 

 Three small, triangular points, two with side notches (Cole and 

 Deuel, 1937, type 4), suggest a Mississipian tie. Two examples 

 were excavated from the 0.0-0.5 foot level, the other from the 2.0- 

 2.5 foot level, the latter in an area of rodent disturbance. It seems 

 probable, in the light of other associated data, that all three can be 

 attributed to the most recent horizon of the deposit. Bennett (1945, 

 p. 91) notes that similar points, lacking side notches, are associated 

 with Lake Michigan pottery in a late context from Wisconsin. A 

 similar association is present in Minnesota (Wilford, 1955) and in 

 Jo Daviess County, 111. (Bennett, 1945, p. 75). 



Knives-scrapers. — Knife or scraper forms are discontinuously dis- 

 tributed throughout the ceramic horizon of the occupation. Spe- 

 cialized varieties (A, B above), however, are restricted in number 

 and do not occur below the 2.0-foot level. It is unfortunate that the 

 knife-scraper sample is not sensitive in terms of available compara- 

 tive material. 



Oelts, choppers, hammer stones. — Chopping tools are restricted to 

 the upper portion of the ceramic horizon, but only one distinctive or 

 specialized form was recovered — a "Woodland" grooved ax of non- 

 specific comparative value. Hammerstones, while relatively abun- 

 dant, are limited to the lower half of the ceramic occupation.
