EASTERN IOWA PALEOENVIRONMENTS AND CULTURAL CHANGE: INTRODUCTION AND PALEOECOLOGICAL BACKGROUND
Summary
This paper provides an overview of the results of archaeological and paleoecological research at the Gast Farm and Gast Spring alluvial fans along the western side of the Mississippi River Valley, in southeastern Iowa. Archaeological survey and test excavations were undertaken to examine the impact of changing ecological parameters on local cultural groups. Most alluvial fans in the Project area contained small surface deposits of Woodland material, but one large fan, the Gast Farm site, contained substantial Middle and Late Woodland communities, as well as buried Archaic deposits. Preliminary analyses suggest a process of nucleation from the surrounding region after the Early Woodland period. Paleoecological investigations established a record of Holocene vegetation changes, beginning with late Pleistocene spruce-larch forest, giving way to deciduous forest, followed by a period dominated by grass and chenopods. The timing of prairie establishment is uncertain, however, and the subject of future research.
