Archaeological Investigations in Jefferson County, Mo. 205 
VI. CULTURAL RECONSTRUCTIONS 
AND AFFILIATIONS 
The Woodland Pattern sites were indicated mainly by 
the following traits: Herculaneum Cord Roughened grit tem- 
pered pottery, one pottery shape, predominance of coarsely 
chipped stemmed projectile points, no evidence of agriculture and 
a lack of burial goods with bodies flexed or partly articulated. 
The Mississippi Pattern sites were indicated by Imperial Plain 
shell tempered sherds, comparatively small numbers of flint 
projectile points, small well-chipped isosceles triangular projec- 
tile points, polished celts, extended bodies usually with grave 
turniture and evidence of extensive agriculture. 
A third Pattern is represented by the discovery of the long 
projectile points and curved blade without pottery associations 
from the lowest levels at the Hidden Valley rock shelter. It is 
too early to define this pattern clearly but pottery is scarce if 
present at all. It appears to have been entirely a hunting mani- 
festation and is probably very old. Typologically the artifacts 
are by no means crude so that the pattern is in all probability 
post glacial but the conditions under which they are found re- 
flect considerable age. 
Evidences of three or four phases of the Woodland Pattern 
have been definitely discovered. Two of these are represented 
at the Pittsburgh Landing site and in the middle occupations at 
the Hidden Valley shelter. A third is represented at the St. Jo 
mound and village. 
All of the objects from the Pittsburgh Landing village site 
indicate a Woodland group that had not come into contact 
with Mississippi groups. There were good indications that much 
of the original habitation level had eroded away. Only Hercu- 
laneum Cord Roughened pottery was found next to small 
irregular fireplaces. A crude flat pottery disc with a 
perforation for holding a drill, contracting stemmed projectile 
points, oval flint knives and a thin limestone ax with flaring bit 
complete our cultural inventory. This component certainly be-
