ABSTRACT
The second epoch of moundbuilding centers took place during the Woodlands Period, a millennium dated roughly from 500 B.C. to A.D. 500. The centers first appeared among peoples of the Adena culture (about 500 to 100 B.C.) in what is now central and southern Ohio, along tributaries that flow into the Ohio River. While the Adena culture was flourishing and spreading up and down the Ohio River, peoples throughout much of Eastern North America began to manufacture pottery. Around 200 B.C. a second moundbuilding culture, the Hopewell, emerged in Ohio, and soon thereafter corn-cultivating, Hopewellian-style centers appeared throughout the region. These centers were all part of an interaction sphere that merged the various exchange zones of the Late Archaic Period into a single network and created the cultural continuities that characterize the moundbuilding region.
