To quickly assess the difficulty of the text, read a short excerpt:
It will be noted that its presence in the pollen profile is correlative with a layer of sandier sediment. I consider it quite possible tliat the increased percentage of cheno-am pollen reflects nothing more than the immense amount of sediment disturbance which may have resulted from the construction of mounds at Cahokia--perhaps Monks Mound which is only a couple of hundred tneters distant. The dating of the Zone Ill-Zone IV boundary is an unresolved matter, as is the dating of the base of this... pollen profile. I can only say at present that the chronology is no older than the oldest date that can be assigned to Old Village pottery. According to archaeological esti- mates now prevalent this would be about 700 A„D. In summary, the oldest date that can be as yet assigned to the pollen chronology from the American Bottoms is in the neighborhood of 700 A. D. , thus- the chronology goes back, roughly, 1500 years at most. All pollen zones show a primarily non-forested, or prairie, ecology though this is recognized as having undergone changes through time which may have had significant effects on the cultural phases of the area.
