ridges in the northwestern part of the county where he located 
aboriginal flint quarries.1_ Mr. Fowke also placed a trench in 
the famous bone bed at the union of Rock Creek and Little Rock 
(Black) Creek.? 
The Academy is carrying on investigations here also with 
a view to determine whether or not man lived at the time of 
the mastodon.* 
The author and Frank Magre carried on a surface survey 
over the county before the present investigation started. This 
survey served as the groundwork for our present investigations. 
The results were published in The Missouri Archaeologist.* 
PURPOSE OF INVESTIGATION 
This area in Jefferson County was chosen for investigation 
because of its nearness to the Mississippi River which served as 
a highway for primitive migration. It was selected also to con- 
serve the rapidly disappearing evidence since all of the mounds 
in this area either have been pitted or destroyed, and the plow 
each year is removing much of the superficial village deposits. 
Two kinds of terrain, the high hills and the low bottom lands, 
also afforded us the possibility of obtaining cultural contrasts 
valuable for reconstructing the life of the past. 
Our basic problems are fourfold: 
(1) to determine, if possible, when man first arrived in the area, 
(2) to define and compare cultural complexes with those of other 
areas, (3) to determine culture sequences through typological
