Fig. 4. The Rouge River-West Duffins site sequence of the successive Draper, Spang, and Mantle sites modeled as an ordered sequence of sites as indicated by the ¹⁴C data (see text) and existing archeological assessments (3, 14–16) with intervening trapezoidal boundaries (49) to allow for some overlaps.

(A) The site sequence uses the data from Fig. 3 with analysis using OxCal (32, 35), including the Charcoal Outlier model for dates on wood charcoal (35) and using IntCal13 (34). The A_model and A_overall values of 65.7 and 64.8 are above the satisfactory value of 60. (B) Details on the modeled dates for the Draper, Spang, and Mantle sites—contrasted with the currently accepted dates for the sites (3, 14)—and for the transitions between Draper and Spang and between Spang and Mantle (see also Table 2).
