BURIAL MOUND PERIOD: Penultimate period of eastern North American prehistoric chronology, from 1000 bc to ad 700. Formulated in 1941 by J. A. Ford and Godon Willey, the total chronology, from early to late, is Paleoindian, Archaic, Burial Mound, and Temple Mound. The Burial Mound I period (1000–300 bc) covers the transition from Late Archaic to Early Woodland ways of life and is associated especially with the Adena culture. Burial Mound II (300 bc to ad 700) is associated especially with Middle and Late Woodland groups, especially the Hopewell.
