- EcKx-4, Sinnock: This is a single component bison kill and butchering station assigned to the Plano horizon of the Palaeoindian tradition. It cannot have been occupied much earlier than the age given by OxA-116 due to the presence of glacial lake Agassiz. The modern age found for OxA-115 is not unexpected given the shallowness of the deposits at the site. This bone occurred 5-10 cm below the surface and could have been trampled to that location. The Palaeoindian occupation level occurs 15-20 cm below the surface. Although found on the surface, the bone dated by OxA-116 had previously been shown to be of great antiquity by a flourine test performed by R. Callaghan. Beta-4868 and OxA-508 consisted of 800 g of fill from a pit feature containing fine organic sediments with charcoal inclusions, and it is presumed to have been contaminated with carbon younger than the Palaeoindian occupation. The pit feature was filled with soil and contained dispersed charcoal, together with heat-treated chert. This feature, possibly a burial (but preserving no bone), was suspected to be younger than the rest of the site, but in the absence of diagnostic artifacts no firm statement could be made.
