67 <br />Simple bifaces: asymmetrical forms. FOUrteen SpeCimenS (Fig. 6e-g). <br />• Description: asymmetrical about the longitudinal axis, possibly sym- <br />metrical on the lateral axis, but indeterminate due to the condition <br />of the specimens. With one exception, fragments are wide compared to <br />estimated length. Generally, they include a straight edge opposed by <br />a curved edge, suggesting a "D" shaped or semicircular silhouette. <br />Materials: chert <br />Edge angles: 45°-60° <br />Flaking patterns: irregular oval and expanding flake scars covering <br />both faces, edge retouch and generally elongated or expanding scars. <br />Edge wear: two specimens exhibit gouging on the straight edge with <br />limited grinding on the curved edge. Two exhibit gouging and step <br />fracturing on the curved edge and no discernable wear on the straight <br />edge. <br />Size range: length, unknown; width, 23-78 mm.; and.thickness, 6-8 mm. <br />Special notes: considerable range in size is evident but no special <br />morphological characteristics show up to differentiate between items <br />of different sizes. <br />The asymmetrical fragments are much like the symmetrical forms <br />in manufacturing technique, material, and apparent wear. The dis- <br />tribution appears to be similar as well, considering the possibility <br />that these could be fragments of similar tools, only derived from <br />different locations on those tools. These biface fragments provide <br />~~~ little diagnostic information other than affirming the fact that <br />such tools were utilized in the Williams Fork Mountains as well as <br />in a wide area surrounding the surveyed acreage. <br />Correlations with other sites: see symmetrical forms above. <br />Simple bifaces: tip fragments. Eleven specimens. <br />Description: generally sharply convergent margins, bifacially worked <br />and relatively thin. These represent complete items having a marked <br />taper in at least one direction. <br />Material: chert. <br />Edge angles: 30°-58°. <br />Flaking patterns: overlapping elongated oval with dissimilar treatment <br />of opposite edges, three specimens in this group; parallel elongated, <br />two specimens; irregular, six specimens. <br />Retouch orientation: most are irregular to perpendicular with respect <br />to edge. One has flake scars at an ob]ique angle. <br />Edge treatments: three serrated edges, eight unserrated. <br />Edge wear: several show gouging wear and step flaking. Five have light <br />grinding or smoothing; one specimen has longitudinal impact fracture. <br />.. <br />
