Timeline

The Early Woodland period is indicated with a green circle; Middle Woodland with a blue triangle; and Late Prehistoric with an orange rectangle. Click and drag the timeline either left or right to view it in its entirety. A selection of contextualizing world history dates are indicated with a black triangle. Only a selection of important sites have been entered for each culture in order to maintain readability and interest. 

For many of the dates, the grey line indicates either the range of suspected dates or the entirety of its lifespan as a known useful site (i.e. the beginning and end of material which can be radio-carbon dated and affirmed.) As with many eras in history dates are far from exact and must be treated with due caution.
