MOUND NO. 7 



The length of mound No. 7 is 50 feet, the width 17 feet, and the 

 height 1.0 feet (fig. 14). The mound was sampled via a 20-foot 

 trench oriented to parallel the apparent long axis of the structure. 

 A second trench, deriving from a sterile platform to the southeast, 

 intersects the first to form an L-shaped excavation (pi. 19, h). All 

 trenches were based upon a 5-foot square unit with a 0.5 foot vertical 

 control. 



STRATIGEAPHT 



Two strata are present (fig. 16) : 



4. A basal structure of friable loessic clay similar to the indigenous soil 

 pattern. 



B. An overlay of loosely compacted brown clay separated from stratum A by 

 a visible unconformity. No other evidence of an old soil surface is pres- 

 ent. It seems probable that the latter was removed prior to the con- 

 struction of stratum B. 



ARTIFACTS 



No artifacts were recovered from mound No. 7. 



ANALYSIS 



Mound No. 7 is summarized below: 



Linear form 



Turf probably removed prior to construction 



Constructed as a single component 



Mound No. 7 suggests a much simplified Effigy-linear pattern as 

 outlined by Bennett (1945, p. 101; cf. Rowe, 1956; below). Logan 

 (1955, p. 128) groups conical and linear mounds in northeastern 

 Iowa as a potential but apparently as yet undefined unit. It should 

 be noted that the simple conical mounds of the Chapman Site in Jo 

 Daviess County, 111., may be most closely related to the linear struc- 

 tures (Bennett, 1945, p. 104). Both linear and conical mounds are 

 definitely associated with the Effigy Mound Culture of Wisconsin 

 (Rowe, 1956, table 1, p. 15, passim) . 



ANALYSIS AND RECAPITULATION (13JH3 AND 13JH4) 



A total of only five artifacts were collected from the three mounds 

 sampled at Site 13JH4. Only two of them possess comparative value. 



The conical pipe, by no means as omnipresent as the elbow or 

 platform varieties, is nonetheless present in the literature (McKern, 

 1928, pi. LIII, 2), occurring in an Effigy Mound context. 



The single comer-notched point (type 1, Cole and Deuel, 1937, 

 pp. 53-55) is conventionally described as "Woodland." It is similar 

 to but not identical with examples occurring in the Effigy Mound 

 Culture of Wisconsin (Rowe, 1956, figs. 23, 25).
