BIFACE This is the fourth largest biface in the cache. Both sides were thinned by striking off large percussion flakes. This picture illustrates a long percussion flake that was struck off at an oblique angle diagonally across the center. This flake was originally over 3 inches (7.6 cm) long. The other side has three large percussion flake removals that cover over half of the surface. This biface was made of Burlington chert and it measures 4 11/16 inches (11.9 cm) long, 2 11/16 inches (6.8 cm) wide and 3/4 inch (1.9 cm) thick.
