LATE STAGE BIFACE
This is the largest biface in the McKinnis cache and the best representation of a recognizable Clovis shaped artifact in the cache. The lanceolate shape and "classic" Clovis flaking pattern suggests that this is a late stage preform for a Clovis point. It was made with edge-to-edge percussion flaking. Several large percussion flakes extend nearly across one edge to the opposite edge. A large thinning flake was also struck from the base. This late stage preform was made of Burlington chert and it measures 5 5/8 inches (14.3 cm) long, 2 1/8 inches (5.3 cm) wide and 9/16 inch (1.4 cm) thick.
