TO PAGE 2
This is the largest biface in the McKinnis cache and the
best representation of a recognizable Clovis artifact. Its
lanceolate shape and 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 from 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.
