TO PAGE 2
This biface illustrates a classic break pattern that is often
found on Clovis camp and manufacturing sites. These over
shot flakes represent a fracturing pattern that is generated
from an edge-to-edge or "outre passe" style of percussion
flaking. This flintknapping technique represents an
important diagnostic element of Clovis stone tool
manufacturing technology. These unique flakes help
archaeologists identify a Clovis site. This biface is made of
Burlington chert and it measures 4 5/16 inches (11 cm) long,
1 11/16 inches (4.3 cm) wide and 7/16 inch (1.1 cm) wide.
