Bone-antler. — Bone and antler remnants evidencing human altera- 

 tion occur throughout the ceramic horizon, but definitive tools 

 (splinter awls) occur only in surface levels. They have limited 

 comparative value. 



European Materials 



European materials are concentrated in the upper portion of the 

 deposit, with one exception noted at the 2.5-3.0-foot level. The latter 

 lies within a locus of extreme rodent penetration. The object, a 

 china cup handle, obviously represents a later intrusion. 



ANALYSIS OF SITE 13JH202 



The aboriginal occupation of 13JH202, as expressed in terms of 

 stratigraphic depth, was a relatively long one. The lower levels 

 (stratum A) cannot be equated accurately to any particular cul- 

 tural manifestation or temporal range. The physical transition from 

 stratum A into stratum B is not markedly abrupt ; however, a slight 

 disconformity is present within the northern and northeastern por- 

 tions of the deposit. Currently, there seems no reason to attribute 

 substantial age to stratum A. In terms of subsistence orientation, 

 A is identical with B, but with the latter suggesting a greater in- 

 tensity of occupation. Stratum A contains a much heavier accumula- 

 tion of rock fall than does B. It seems necessary to assume that 

 there was somewhat heavier precipitation, at least seasonally, during 

 the span of stratum A. The occupation of stratum A must have been 

 seasonal. Winter and spring frost action would have rendered the 

 site untenable. Stratum B indicates much more stability and hence 

 presents the possibility of long-term, annual occupations. The defini- 

 tive occupation of the latter stratum falls within the middle to late 

 Woodland range, possibly very late, in the terminal phases. 



The local miconformity separating strata A and B suggests only 

 a slight and local stabilization of surface. Therefore it seems rea- 

 sonable to consider the deposits of A as representing Archaic or early 

 Woodland seasonal camp debris with no necessary connotation of 

 extreme age. 



The overwhelming dominance of a single ceramic type within 

 stratum B suggests the presence of only a single component. In 

 terms of the published data, this horizon most closely resembles the 

 occupation of Minott's Rock Shelter (Keyes, 1943), situated in Linn 

 County, Iowa, appromixately 12 miles northeast of 13JH202. Al- 

 though the Minott presentation is lacking in detail, the major ceramic 

 and lithic remains appear to be quite similar. Cord-marked Lake 

 Michigan ware is dominant at both sites. In addition, the ashy, 

 shell-and-bone-bearing cultural stratum in the Minott shelter (ibid., 

 pp. 23, 31-32) appears substantially similar to stratum B (above).
