Lanceolate shaped, the upper lateral edges of the most Plainview points are slightly rounded but on some they are straight. Lower lateral edges are ordinarily straight and parallel-sided up to about one-half or three-quarters the distance from the base to the tip. They are usually broadest at mid-section. A variation in shape may include a recurve, rarely marked, of lateral edges near the base; such specimens are broadest either at or somewhat above the mid-section (see also the description of Golondrina points). The base of Plainview points varies from slightly to markedly concave; the former is typical. Workmanship is quite fine. Direct or indirect percussion or possibly pressure action is employed in retouching. Initial flake scars may be at either right angles or slightly oblique to the point long-axis. Though individual initial flake scars may be parallel, they are more often irregular. Dimensions of Plainview points are: length about 4.5 to 8.0 cm., width 1.8 to 2.8 cm. Bases of these points were sometimes thinned by the removal of the series of relatively large, longish flakes parallel to the point long-axis in a technique reminiscent of fluting. Others however, were basally thinned by the removal of flakes from the lower lateral edges at right angles to the point long-axis. Basal edges are usually smoothed. Plainview points are considered by most archaeologists to date around 9,000 to 10,000 years ago. At both the type site and at the Lone Wolf Creek Site in Texas, they were associated with the remains of extinct bison. MILNESAND POINTS Milnesand points were first recorded at a site near Milnesand, New Mexico. [Illustration: _Milnesand_] Lanceolate in shape, Milnesand points are broadest either at mid-section or somewhat above. Upper lateral edges are slightly to markedly rounded, while the lower edges are straight and taper a little towards the typically straight base. Bases on some may be slightly rounded or concave. Average dimensions are: length 5.0 to 8.0 cm., width 2.0 to nearly 3.0 cm. Workmanship is generally quite fine, and has been achieved with either direct or indirect percussion, or possibly pressure. Secondary thinning of both lateral and basal edges often occurs and is by pressure. Initial flaking of point faces is patterned: transverse flake scars are approximately parallel to one another and at right angles to the point long-axis. These scars terminate at the point mid-line; some specimens may have a distinct median ridge on one or both faces. Horizontal basal thinning, accomplished primarily during initial flaking may be accompanied by the removal of small flakes vertical to the point long-axis. Both the lower lateral edges and base are carefully smoothed.
