BIFACE CACHE The ten bifaces in this picture are casts of the original bifaces that were found on the Lamb site and identified as a cache. Two fragments of one additional biface was also found. Most of these bifaces are described as fluted point preforms. The two examples at top right are described as blocky ovate biface knives. All of the bifaces were made from light and dark gray and bluish-gray colored non-local cherts. The material is identified as coming from the Pennsylvanian geological formation either from Ohio or Indiana. The longest biface measures 4 1/4 inches (10.7 cm) long. Two of the widest bifaces both measure 1 3/4 inches (4.4 cm) wide.
