6E <br />Simple bifaces: symmetrical forms, Type IC. Nlne specimens (Fig. 6d, h). <br />Description: bilaterally symmetrical about the longitudinal axis, gen- <br />erally with biconvex cross section, a convergent silhouette which tapers <br />from the fracture to the end giving a somewhat triangular appearance to the <br />fragment. <br />Materials: chert and quartzite. <br />Edge angles: 45°-60°. <br />Flaking patterns: overlapping oval to overlapping elongated shapes. <br />Where pressure flaking is present, they take the form of overlapping <br />elongated shapes. <br />Edge wear: ranges from step flaking on the three narrowest specimens, <br />to gouging wear (Judge 1973:155) on the widest. A single specimen ex- <br />hibits polish on its working end. <br />Size range: length, 59 mm. for the single specimen for which length <br />was obtainable; width, 25-41 rnrn.; and thickness, 4-9 mm. <br />Special notes: five of the nine specimens are fractured transversely <br />and provide no clue as to the original silhouette. Only one specimen <br />is complete enough to determine the true outline. This has slightly <br />rounded ends, one broader than the other; and the one complete longi- <br />tudinal edge is relatively straight. <br />The symmetrical biface fragments exhibit several characteristics <br />which might otherwise serve to differentiate them more finely than has <br />been done here. The major criterion is symmetry about the longitudinal <br />axis, rather than the actual shape. Complete artifacts of a similar <br />nature illustrated in Breternitz (1970) and Wormington (1955), for <br />example, show that a given biface type in many cases has both pointed <br />and rounded ends, squared and rounded, or even squared and pointed. <br />Thus, on the basis of fragments alone it would be difficult to assign <br />any to a particular category of "rounded-end bifaces" or something <br />similar. The consequences of such sorting are obvious, as both pointed <br />and rounded fragments are present in the symmetrical forms category. <br />A larger sample of complete specimens is needed in order to obtain a <br />more definitive typology. <br />Generally, the fragments represented here exhibit fairly uniform <br />and well-defined flaking technique. Whether or not these are fragments <br />or tools of similar size is debatable, but the inference could be drawn <br />that a fairly wide range of size exists. Edge angles are confined to <br />a narrow range, which could suggest similar kinds of usage. Abroad <br />spatial distribution exists for these tools. <br />Correlations with other sites: similar items have been recovered from <br />sites in eastern Colorado in Cedar Point Village and other related sites <br />(Wood 1971), the Front Range at the LoDaisKa site (Irwin and Irw-in, <br />1959), northwestern Colorado in Dinosaur National Monument (Breternitz <br />197~~), the Turner Lake site in Utah (Worming ton 1955). This is a <br />small sample of the distribution, but serves to illustrate the spread <br />of tools which would produce fragments of this nature. <br />r 1 <br />L.J <br />
