Helton Phase

The latter part of the Middle Archaic period saw the rise of the Helton phase in the lower Illinois Valley. The artifacts discovered at the Koster site in west-central Illinois were remarkable because of the evidence of ground and pecked chert implements such as woodworking adzes, stemmed points, grooved axes, and improved weights for atlatls. Technological innovations possibly resulted from shrinking territory, climatic changes, or other unknown factors.

Evidence gathered from burial sites indicates a gradual movement from roving hunting bands to more settled peoples who engaged in some primitive agricultural practices and left behind camp debris, middens, and mounds full of lithic and bone remains. Some of those remains include antler hooks, handles, projectile points, stone atlatl weights, axes of at least three types, bone awls, and engraved pins. Most remains are those of women and children, with an occasional dog, leaving modern investigators with little more than intriguing bits and pieces of the picture of Helton phase life.
