It seems appropriate, particularly in the light of the recent radiocarbon dates for an Old Copper site, that the accumulated information about the Old Copper complex be summarized for the use of those interested in the prehistory of the Northeast. While some of the data presented here have been previously published in greater descriptive detail, they are briefly reviewed because they represent the factual basis for the definition of the complex as a local cultural variant in the Archaic period. The radiocarbon dates and certain new data add materially to the basis for the interpretation of the remains of these early inhabitants of Wisconsin. We use the term “Archaic” to refer to a time period rather than a cultural assemblage, although we shall discuss the cultural traits that appear to fit into this time period in the locale under discussion.
