Additional information
This date represents either a forest fire or an occupation by people using Plains side-notched points.
DgPl-42: Three main occupation levels were distinguished at this site. The lowest, Level 1, consisted of at least four living floors in Unit B alluvium, the latest in the surface of the alluvium, 25-30 cm depth, and the earliest at the base of the alluvium on top of underlying red clay. Level 1 yielded mainly Pelican Lake corner-notched points along with a few other varieties and represents the local Blue Slate Canyon phase. Level 2, assigned to the local Crandell Mountain phase, yielded Avonlea points in the base of Unit C colluvium, but this level was badly disturbed and contained few artifacts. Level 3, in the Ah horizon, represents the local Pass Creek Valley phase with Plains side-notched and Plains triangular points. GX-1272 and GX-2049 were collected from the top of the Unit B alluvium, but the matrix was difficult to distinguish from the overlying Unit C colluvium (Reeves, 1972: 64); these dates might pertain to the Avonlea points. GX-2014 may date a forest fire that burned the upper surfaces of the bones in Level 3 (Reeves, 1972: 70). The site had been heavily disturbed, especially in the upper 30 cm, by rodent burrowing, aspen roots, and a historic wagon road. As a result, "a Pelican Lake Corner Notched point was found 10 cm below the surface, and resharpening flakes from the same biface were recovered from depths of 20 and 50 cm in the same unit" (Reeves, 1972: 66).
