McKINNIS CLOVIS CACHE
ST. LOUIS COUNTY, MISSOURI
DONNIE McKINNIS COLLECTION
RETURN
TO PAGE 1
This biface is impressive for its large diagonal percussion
flakes that were struck off on one side. Striking off very large
flakes from all angles across the surface of a biface is a Clovis
manufacturing technique. The intended purpose for this early
stage preform was probably to make a fluted point. This
biface is made of Burlington chert and measures 4 3/4 inches
(12 cm) long, 2 5/8 inches (6.7 cm) wide and 3/4 inch (1.9 cm)
thick.
