A total of 106 flake knives was found at the site. This class is divided into the following two types: Type I: These are flakes struck from a prepared core surface—the Levallois Technique. Fifteen examples were recovered from the site (Fig. 61, a-g). The shape of the flake was predetermined by removing smaller flakes from the surface of the core and by preparing a striking platform. The more classic examples of the Levallois Flake tend to be somewhat oval in shape (Fig. 61,/and g). Type II: These are random flakes and pieces of shatter with retouched edges. A total of 88 of these tools was found (Fig. 62, a-o). All types of flakes were represented in this collection, including expanding, contract- ing, and irregular flakes, as well as both primary and secondary decorti- cation flakes (White, Binford, and Papworth, 1963, p. 5). The flakes varied in length from to cm., and in width from to cm. The frequencies of occurrence of the length and width dimensions are shown in Figure 63.
