Significance
Late Archaic; Archaïque supérieur
Context
Zone C, a Late Archaic component, 20-23" depth, with 4 projectile points. Zone C. Assoc with 4 proj pts, all with low Zea mayser/side notches. Appear to be poorly made, but hard to tell from the photo. The humic acids were NOT removed, so the date may be inaccurate even though it was consistent with what this Zone was thought to represent in terms of time.
