80 <br />• portion of the blade. The nature of the wear visible on the shorter ed~le, <br />and the lack of wear on the opposing edge, supports the former supposition. <br />It is difficult to determine whether or not this is the result of use or <br />intentional smoothing for some other purpose. <br />Perforators and graving [oo1s: eccentric, Type IL. Dne Specimen (Fig. 9n). <br />Description: a roughly triangular fragment of a bifacially worked flake. <br />It is flaked over all of one face and retouched on the other. Four inten- <br />tional indentations are visible, near the intersection of the edges. The <br />original outline is unknown, as the item has a transverse fracture on one <br />side. <br />Material: chert. <br />Flaking patterns: irregular overlapping oval and elongated flake scars <br />visible. <br />Edge wear: both remaining edges show step flaking. <br />Size range: length, 34 mm.; width, 29 mm.; and thickness, 4 mm. <br />Special notes: there is little that can be said regarding this item as <br />it has readily apparent function and is incomplete. There has been much <br />speculation as to its use, but nothing concrete can be said of the object. <br />Correlations with other sites: none. <br />• Unifaces. The sample is very small, comprised of only a few complete <br />specimens and a handful of fragments. Thus, it appears that the typology <br />has been finely divided, but there is little comparable material from <br />other sites, and it is difficult to determine the extent of internal <br />variation when only a small sample is available for study. <br />unifaces: transverse edge. Type 77A. Three specimens (Fig. 9a, b). <br />Description: tools consist of heavy flakes with unifacial retouch on one <br />end, perpendicular to the long axis of the flake. The shape of the tools <br />vary, but the working edges are consistently convex. <br />Edge angles: 70°-80°. <br />Materals: chert and quartzite. <br />Size range: length, 33-40 mm.; width, 17-33 mm.; and thickness, 5-17 mm. <br />Edge wear: limited step flaking. <br />Variation: two of the three specimens have working edges extending the <br />full width of the flake. The third specimen has a very limited area of <br />steep retouch and use, although some minor utilization of an unmodified <br />side is visible. <br />Correlations with other sites: Frison (1967) reports similar triangular <br />end scrapers from 48J0312 in northern Wyoming; comparable nosed and pris- <br />matic end scrapers have been found at the Magic Mountain and LoDaisKa <br />• sites (Irwin and Irwin 1959, Irwin-Williams and Irwin 1966). <br />
