The penultimate period of eastern North American prehistoric chronology, from 1000 BC to 700 AD. Formulated in 1941 by J.A. Ford and Godon Willey, the total chronology, from early to late, is Paleo-Indian, Archaic, Burial Mound, and Temple Mound. The Burial Mound Period I (1000-300 BC) covers the period of transition from Late Archaic to Early Woodland ways of life and is associated especially with the Adena culture. Burial Mound II (300 BC-700 AD) is associated especially with Middle and Late Woodland groups, especially Hopewell.
