Comments
DjPn-9: Citing Quigg and Reeves (1975), Driver (1978: 100) notes that Level 1 contains Bitterroot side-notched, Oxbow, and Pelican Lake corner-notched points in one component which may be mixed or disturbed. Level 2 yielded Bitterroot side-notched, Kootenay side-notched, and Pelican Lake corner-notched points, prompting Driver (1978: 104) to suggest that it is a mixed assemblage. Level 3 contained Plains side-notched points. In Driver's view, all of the dates from DjPn-9, except RL-418 on Level 3, are anomalously young. Driver (1985) considers this site to have served as a winter camp during all three occupations.
