- BbGu-?, Deavitt (7Yk10): This Late Palaeoindian site is considered to represent the Madina Phase of the central Ontario sequence, with an age between 10,400 and 10,100 BP (Dibb, 2004: 117). Like many such sites, direct dating of the site is complicated by shallowness of the deposits, the integrity of which may be compromised by ancient and recent tree throws and root penetration. Feature 4, recognized at Deavitt, provides an example. More than 1 m in length, it contained abundant Late Palaeoindian artifacts, and three pits could be recognized within it (Dibb, 2004: Fig. 5.5). Conifer charcoal from Pit III yielded a mid-Holocene age, and "it is felt that the feature is a tree and/or root stain that overlies a Late Palaeo-Indian hearth or pit, which is preserved in Pit II" (Dibb, 2004: 130).
