MIDDLE WOODLAND POTTERY TYPOLOGY FROM SOUTHWEST IOWA

This paper presents a typology for Middle Woodland pottery from the vicinity of Glenwood, southwest Iowa. It shows that the Glenwood materials have their closest Plains affiliation with Valley Cord Roughened and their closest Eastern Woodland affiliation with Havana tradition pottery of the Illinois River Valley. The main source of influence for the Valley Focus seems to have come from the Eastern Woodlands and not from the Hopewellian instrusion at the Renner site. Finally, it is argued that the Valley Focus and related materials originated in the Middle Woodland period, were composed of generalized Woodland traits, and were imposed onto the life styles of indigenous peoples on the Central Plains.
