Square 411, level 12, horizon 4B, 1.23-1.31 m depth, north of the macroblock excavation area, considered intrusive in this stratum because it is much younger than the Archaic period context (Conard et al. 1984:445, Table 1).
This date has been reported in the Canadian Archaeological Radiocarbon Database (CARD) (Morlan and Betts 1999).
